Billy perrin, our publisher, and my mentor, who has more than twenty years’ worth of experience in the publishing industry and a nose for great ideas, established Trademax

Publications with its flagship title, SA Roofing magazine, in May 2008. five years later, the company’s stable of publications includes another two titles, Sa affordable housing magazine and Timber iQ, and is poised to expand its product offering further.

Being involved with a publication such as SA Roofing, which is an established mouthpiece for an industry that is concerned about the end-user as much as it is about the bottom line, is truly inspiring, and I can safely say that we, at the SA Roofing magazine, are proud to showcase the excellent products, services, systems and projects the South African roofing industry has to offer.

although I have not accompanied Billy from the start of this wonderful journey, I am so proud of how far we’ve come, of what we’ve all achieved, and to be here now.

My colleagues at the SA Roofing magazine are always brimming with ideas, excited about every new issue, and are supportive beyond measure. you can read more about them on page 10.

Congratulations, Trademax Publications and SA Roofing, the magazine that started it all, on your fifth anniversary. Here’s to the next five years and the next fifty issues!

The SA Roofing team thanks our advertisers, editorial contributors and readers for their continued support over the past five years. It is because of you that we have the privilege of celebrating this significant milestone.

welcome to our special 5th anniversary issue of the Sa Roofing magazine. Enjoy the read.

why arE INspEctIoNs NEcEssary?

In terms of the National Building Regulations (NBR), the owner is responsible for his roof structure, regardless of the type of building (house, office, hospital, etc.). In fact, the rule is that where a rational design is used, a professional competent person must be appointed by the owner to carry out that design. The roof inspection is an important part of the design process, and therefore the engineer (or his qualified appointee) must inspect the completed roof.

whIch rooFs NEEd to BE INspEctEd?

all rationally designed roofs need an inspection by the design engineer or his competent appointee. Roofs built in accordance with the ‘deemed-to-satisfy’ rules of the NBR should be checked for compliance by the architect/owner/building inspector. No engineer is required. The short answer therefore is: “all roofs need to be inspected.”

who pays?

The owner is responsible for payment, either as part of his roof supply invoice or his fees payable to the professional team.

who caN INspEct?

The designer or his qualified appointee, provided that the designer is a registered person with ECSa (Engineering Council of South africa) who is competent by virtue of his/her education and experience. for example, a registered lift inspector cannot inspect or sign off a roof, and neither can a registered chemical or electrical engineer.

timber roof inspections: why, when, by whom?

There are a number of questions that are regularly posed regarding roof inspections, mostly because they cost money. In this article, ITC-SA Board

Member, Roly Adams provides answers to a few of these.Words: Roly Adams Pr Eng and Board Member of the ITC-SA

The appointment of an engineer for the whole project means that the connection between the roof (designed by a specialist) and the walls can be monitored and checked. The roof in this picture failed, because the connection was not installed as intended by the roof designer, and he was

never called to site to check (money saved upfront on inspection fees spent x 100 on repairing the roof!).

who caN sIgN oFF?

It is the designer – not his appointed inspector – who takes full responsibility for the design and who should, in his own interest and that of the client, have professional Indemnity Insurance.

shoUld thE FaBrIcator INspEct hIs owN rooF?

yes, in order to save time and money and to help train the erector. This is an ideal situation, but does not happen often. Once the fabricator is satisfied that the roof is right, he can call the engineer to arrange the formal inspection and ‘sign-off’ (refer to ‘who pays?’ above).

A builder who tried to save money building his own trusses ended up costing his client a fortune when the un-triangulated frames failed and insurance would not pay out as the design was faulty.

The leaks in this roof were not caused by poor construction or structural defects in design, but by the owner trying to hide irrigation pipes (routed over the roof instead of underground) in the

concealed gutter, thereby blocking it. He then stuck ‘flash harry’ waterproofing membrane over the valley to try and solve the leaking problem.

caN a FaBrIcator INspEct aNothEr FaBrIcator’s rooF?

Yes, unofficially. Professional ethics, as used by engineers and enforced by ECSa, require that an engineer who inspects another engineer’s work should first inform that engineer of his appointment and give that designer the opportunity to co-inspect. The same standard of ethical behaviour would suggest that any fabricator inspecting another’s work should make every effort to ascertain who the designer or other fabricator is and inform him of the situation.

who Is UltImatEly rEspoNsIBlE For thE complEtEd rooF?

The person responsible is the engineer who signs the completion certificate – the appointed designer. Often, in the case of public buildings, the system engineer is not the appointed engineer, but by signing off the roof and supplying the fabricator with a certificate, he/she accepts that the appointed engineer will look to him/her as being responsible should anything go wrong with the roof. This is why the ITC-SA System Members certificates carefully note the date of the inspection and also note that other trades working on site after the inspection, who may interfere with the trusses, would cause the certificate to be voided (managing this aspect would be the responsibility of the appointed, overall engineer, if there is one, or of the owner who retains overall responsibility).

The lines of the tiles viewed either straight up the roof or at an angle, as in this photo, should be straight; the waviness tells us the roof is not correctly braced and rafters are buckling.

This photo shows signs of imminent sagging; any concave roof plane indicates trouble within (unless it is a pagoda roof in China!).

De Beer says that many of the major South african client companies have introduced a policy known as ‘best country sourcing,’ which means they buy from the

cheapest international supplier, which, in many cases, turns out to be China.

“These companies say that they simply cannot be competitive with other global players if they do not continue with this practice. Many of them have gone to the extent of setting up purchasing offices in China, and other countries, to take advantage of what they call a ‘massive’ price advantage. “But this, in my opinion, is a misperception,” says de Beer. “They haven’t made the right comparisons and they certainly haven’t taken into account the full hidden associated costs of the practice. For example, China typically needs full and final drawings to proceed and they tend to not process variations very effectively and, even if the work is done well, the costs end up high. Many buyers also ‘forget’ the 15% import duty payable on imports of fabricated structural steel on entry into South africa. a number of instances have been found where importers use fraudulent codes to try to avoid paying these duties.”

“also, almost every major company buying from these foreign sources needs a full time resident quality assurance (Qa) team on the premises of their suppliers and, often, a second team to fix the poor quality of the work. As technical communications are also a very real problem, major quality and scheduling issues are not uncommon. These issues have made countries like australia move away from China as a cheap source of supply,” says de Beer

he adds that while it is true that delivery times are generally quick from these Eastern countries, he is convinced that delivery from South african fabricators is just as quick, particularly when taking into account the six weeks' shipping needed to bring foreign supplies. Most buyers also fail to account for the time and effort needed to repair paint and other damage before steel structures can be erected. “Our quality and speed of delivery is on a par with anything in the world and, taking into account the extraneous costs when buying from the East, we are also much closer to being competitive from a price perspective. and the weakening rand has made South african prices even more competitive of late,” de Beer says.

Importing of fabricated structural steel significantly impacts South

African economy

JUNE 2013

The large quantities of fabricated structural steel coming into South Africa from China, Saudi Arabia, India, Turkey, Thailand and others continue to have a

significant impact on the South African economy. This is the opinion of Kobus de Beer, the Southern African Institute of Steel Construction (SAISC) industry

development director.

Kobus de Beer.

“The fact that South africans have managed to export 75 000 tons and more of structural steel per year for the past ten years does indicate a reasonable degree of competitiveness in spite of the many domestic constraints, such as relatively low volumes and the inability to specialise. To give a perspective on this number, it comprises about 15% of the total South african capacity. a medium sized South african structural steel fabricator will employ some 210 people to produce 500 tons a month or 6000 tons a year,” says de Beer.

he says that it’s time the industry took a holistic view and understood that, given South africa’s relative overall competitiveness, buying fabricated steel locally is not only beneficial to them in terms of the overall efficiency of trade, it is also good for the country’s economy as a whole.

“a lot of government and private sector effort goes into creating new jobs and incentivising productivity improvements at South african companies. against this background it is totally counter-productive to allow existing decent jobs of well-trained people to be wiped out while big buyers pay lip service to social compacts and local industry developments while continuing to import fabricated steel and other things.”

“perhaps the best illustration of how the country is affected by these decisions is to examine the losses on a few current jobs as calculated using the ‘multiplier effect,’ which, in essence was developed to describe the knock-on benefits of fabricating steel for construction locally,” says de Beer.

SA Roofing magazine is the only publication in South Africa dedicated entirely to the residential, commercial and industrial roofing and re-roofing industries. The magazine

reports on current issues and topics relating to both inner and outer roofing systems and is widely subscribed to by key players in the roofing and construction industries, as well as the public and private property development sectors.

Main and Sub-contractors (levels 3 – 9 as per the CIDB Register of Contractors), Installers, Manufacturers and Suppliers that serve the construction/roofing/built industry, Developers, Industrial & Commercial property Owners, as well as Building/property portfolio Managers form an integral part of the title’s readership.

Says, Billy perrin, publisher at Trademax publications, “It is heartening to bear witness to the growth and development of a company that began its trade in 2008 during an especially trying time, even for existing concerns. we started out during a tough period for our industry, and for our general economy, and I think this ‘baptism by fire’ has made us more resilient and better equipped to serve our clients as a media partner of choice.”

In 2009, Trademax publications expanded its product offering with the launch of its second trade title, the Sa affordable housing magazine, and, as of March 2012, their stable of publications grew further to include the well-received Timber iQ – Design & Construction.

SA Affordable Housing magazine followed SA Roofing magazine’s unique contribution to the industry by offering stakeholders a novel perspective on the very relevant and pervasive subject of affordable housing in South africa today.

The publication addresses issues relating directly to rural and urban infrastructure planning and development, and sheds light on the delivery of affordable housing. The publication does not support any view that lends itself to the construction of new shacks and slums and is grounded in the conviction that every South african must have access to a home, and that this home, and its supporting infrastructure, must be of a standard that is reflective of the needs and dignity of our citizens.

Trademax publications’ newest title, Timber iQ, celebrated its first anniversary to a warm reception at WoodEX for Africa in March 2012. This glossy bi-monthly has rapidly made a name for itself and is well supported by the industry at large. from saplings and sawmilling to timber homes and objets d’art, Timber iQ features every aspect of timber in all its forms and applications. already having won the hearts of professionals within the timber and related industries, Timber iQ is steadily gaining a loyal support base among consumers as well.

Looking back on Timber iQ’s first year, Billy Perrin says, “We are proud to have celebrated our anniversary in the same fashion that our launch took place. Timber iQ represents an important sector in the South african construction and design industries and has become a well-loved and sought-after magazine for the trade and the consumer. we look forward to many more years of showing off what timber has to offer as both a practical and beautiful resource.”

“I’ve been with Trademax publications for ten months and what a wonderful experience to be part of such a dynamic team. SA Roofing has become such a passion of mine and really has so much to offer, being the only national magazine where all aspects of the roof are reported. I wish Trademax publications, Billy, and our whole team a prosperous and successful journey going forward. Go, SA Roofing!”Jacqui Marsh, Sales Executive, SA Roofing

“Before I started working on SA Roofing, I thought a roof was, well, just a roof. But as I began to learn about the industry and better understood the inner workings and the different aspects of roofing styles and structures, it has all become so fascinating to me and I have learnt so much. I enjoy working on SA Roofing because it is the only magazine dedicated to the entire topic of roofing; it gives our clients a unique opportunity to showcase their products and services on a platform that no one else has to offer in this industry. SA Roofing has definitely made an impact on the industry in this way and I feel that we bring manufacturers, suppliers and even consumers together in a way that no other publication can – and with SA Roofing, they will be in the right place at the right time.

My anniversary wish for SA Roofing is that the next five years will be just as great as the last!”Bradley Williams, Sales Executive, SA Roofing

The house was designed by the talented duo Johann and friedrich Strey of Strey architects. Called the Barn house, it is built in the contemporary farm-style vernacular and

is far more than just an architectural masterpiece; it also sets a new standard for sustainable living.

Southdowns is an eco-estate that forms part of the Irene Dairy farm, where vast areas of pastures were retained for agricultural use by the original farm landowners.

The house itself is a contemporary interpretation of the local farm-style vernacular, incorporating elements and structures found on a farm as an analogy. The main structure is an insulated ‘barn’ clad in timber decking, with rigid polyurethane board insulation, using glass wool or foil insulation under the concrete floors, the walls and roof, where appropriate. The windows are all double-glazed which, although more expensive initially, will ensure a huge cost saving on the long run by regulating interior temperatures.

ancillary structures on the property, such as the garage, are all corrugated clad to resemble structures on a farm.

“The lap pool is an analogy of a drinking trough for cattle and is positioned upwind in order for a breeze to gather the cooled evaporated air in summer and blow it through the house, thus passively cooling the house,” says Strey. The structures are ‘placed’ around a cylindrical brick stair shaft and entrance hall, resembling grain silos found on farms in the free State. The surrounding landscaping consists of an indigenous garden to the north framed by a very old stinkwood tree. Careful landscape planning ensures that different plants will be in full bloom throughout the different seasons, with little need for irrigation.

The role of metal roof sheeting and its use in the harvesting of rainwater has made a major comeback in green design and architecture. water shortages in the near future are a fact, and careful consideration was given to the harvesting of rainwater and the recycling of water in this project. Rainwater can only effectively be harvested using steel roofing, and the sophisticated paint coating used on Colorplus (Safal Steel) or Clean Colorbond™ (BlueScope Steel) sheets is self-cleaning, ensuring the minimum water contamination.

In keeping with the farm-style theme, corrugated water tanks collect rainwater, which are used for domestic water use, the garden, flush toilets and the swimming pool.

South africa has an abundance of sunlight. The company embraced this by using renewable energy sources for domestic use as well as under-floor and pool-water heating.

Rodney harber, chairperson of the Kwazulu-Natal Institute of architecture (KzNIa) heritage Committee, cites the prime reasons for the renaissance of corrugated roof sheeting. One key reason for using the sheeting is the effective use of metal roof sheeting in the collection of rainwater. according to harber, there is no doubt that corrugated steel sheeting is an excellent material for rainwater harvesting purposes, particularly in rural areas where the technology is understood. “The second reason for using corrugated renaissance is the architectural benefits, as seen in the vernacular of Southdowns Estate.”

harber explains that corrugated metal sheeting had a major impact on colonial architecture in South africa. It could be readily transported on wagons, stacked tightly and securely, was quick and easy to erect on a timber framework, and offered excellent protection from break-ins. “Rainwater harvesting was the norm and roofing materials that facilitated harvesting became entrenched in the architectural style of these times.”

he adds that another major advantage of steel was that it could be reused (or repurposed) if necessary, as a platform for ripening pumpkins, forming rainwater tanks and even for boundary walls. “It is ironic that, in order to preserve precious resources, we are returning to the way things were done before.”

The Department of public works now requires architects to design new public buildings to conform to the guidelines of the green Building Council. for example, toilets need to be flushed with waste water, generally augmented by rainwater.

Strey says that they strived to set an example for South africans by experimenting with high-tech and low-tech solutions in order to minimise their impact on the earth, without compromising on aesthetics and lifestyle. “we hope this project will inspire others to push the boundaries of architecture, and motivate the public to seek out a like-minded and knowledgeable architect to help them fulfil their dream while doing their bit for the future users of the world, our children.”

“Building-integrated photovoltaic (BIpv) solar power systems not only convert solar energy to electricity, but these modules, which are considered to be multifunctional construction materials, also form part of the building envelope,” says Dr Ronald Lange, chief operating officer for ART Solar. “The new global trend is for photovoltaic (pv) modules not to be mounted as a separate item on a building’s roof or facade. In modern installations, BIpv materials are used to replace conventional building materials that include the roof, skylights and facades. These environmentally-friendly pv modules also act as a solar energy system that generates electricity for the building.

“pv technology is gaining popularity as a high value, energy efficient way to generate electrical power at the place where it is needed. This is a reliable form of renewable energy that is clean, emission- and noise-free, sustainable, safe and cost efficient.”

“There is a perception that pv modules can be ‘unattractive,’ but with the latest designs, quality materials and manufacturing techniques, aRT Solar has given architects and designers the freedom to be creative with this flexible building material, with no compromise on performance.”

“pv, which is well integrated into the architectural design of a building, enhances the aesthetics of the building, but its fundamental role is to maximise energy efficiency within a building’s energy demand or load.”

The standard element of a BIpv system is the pv module. Individual solar cells are interconnected, encapsulated, laminated on glass and framed to form a module.

Modules are strung together in electrical series to form a pv array. Direct or diffuse light – usually sunlight – shining on the solar cells induces the photovoltaic effect, generating DC electric power.

This DC power can be directly used, stored in a battery system or fed into an inverter that transforms and synchronises the power into aC electricity. The electricity can be used in the building, or exported to a utility company through a grid interconnection.

an advantage of building integrated photovoltaics over non-integrated, or building added systems, is that the initial costs can be offset by reducing the costs of building materials and labour that would normally be used to construct the part of the building that BIpv modules replace.

aRT Solar’s locally manufactured semi-transparent pv modules are custom-designed, using locally sourced materials, to meet the exact architectural specifications of each project in terms of colour, size, textures, materials and electrical requirements.

pv can also be integrated into sunshade building components. Sunshades are used to minimise the direct solar gain into a building, which also reduces the building cooling loads. The angle of the sunshade can also be set to optimise the output of the pv/sunshade system.

although aesthetic design features play an important role in BIPV, a further benefit of semi-transparent modules compared to traditional light filtering systems, is that high quality natural light is provided inside the building, improving living and working comfort.

Cost efficiency and aesthetics of BIPV systems are optimised when pv is integrated into the building during preliminary design stages. like standard construction glass, cladding and roofing materials, these modules can be easily integrated into the building envelope. It is important that BIpv products match the structural properties, dimensions, features and life expectancy of the materials they replace.

an autonomous or off-grid building may require a large pv system with battery storage capabilities to provide 100% of the building’s electricity requirements. a building owner wanting to reduce demand charges will require a small system that produces electricity during peak utility charge hours.

as architects, designers and builders gain experience in building integrating photovoltaic systems, this environmentally-friendly technology is becoming more popular throughout the world as a reliable, safe, cost efficient and aesthetically pleasing way of generating electricity for industrial, commercial and domestic buildings. aRT Solar is guiding the way in South africa.

zinc electro-plating is an electrolytic process whereby carbon steel has a thin zinc coating deposited by means of passing an electric current between an anode (zinc) and the carbon steel (cathode). It is analogous to a galvanic cell acting in reverse.

a typical process is shown in the diagram below:

• product immersed in a coating solution • DC current passed between the product (cathode) and an

electrode (anode) • Coating governed by:

• Current• Temperature• Chemical composition • process time

• Metals used for electro-plating:• Copper • Nickel• zinc• Chrome

The characteristics of zinc electro-plating are summarized as follows:

• Uniform smooth coating with a bright lustre• Coating thickness usually between 6 to 10 microns • The coating consists of approximately 99% pure zinc• zinc is deposited by means of a cold process• The adhesion of the coating to the steel consists of

‘mechanical bonding’• The process is carried out at normal room temperatures• Product profiles can affect the uniformity of the coating

due to what is known as the ‘faraday Cage effect’

as the name implies the application of the zinc coating is a hot process whereby cleaned steel is immersed in molten zinc usually at a temperature of between 445˚C and 450˚C. when perfectly cleaned steel is immersed into molten zinc, a metallurgical (chemical) reaction results, forming a thick coating comprising mainly of iron zinc alloy layers usually over coated with pure zinc. The adhesion of the resultant coating to carbon steel is therefore determined by means of metallurgical laws and forms a chemical bond to the substrate. Chemical bonding is considered to be far superior to that of a mechanical bond.

The characteristics of a hot dip galvanized coating are summarized as follows:

• Relatively uniform and can range from a bright silver to a dull grey surface finish depending on the chemical analysis of the steel being processed.

• Coating thickness usually between 55 to >100 microns, depending on steel thickness, as well as the chemical composition of the carbon steel being processed.

• The coating consists of a series of of iron/zinc alloy layers, the formation of which is influenced by the chemical composition of the steel being processed.

Note: The metallurgical reaction between molten zinc and carbon steel is a function of the silicon and phosphorous content of the steel being processed.

Corrosion control provided by a zinc coating in a given environment is generally a function of the coating thickness, i.e. the thicker the zinc coating, the longer the service life of the carbon steel component. It therefore follows that a hot dip galvanized coating, by virtue of its thickness, will provide greater corrosion control when compared to that of a zinc electro-plated component. This factor is illustrated by the fact that in most cases, zinc electro-plated components are generally less than 10 microns, whereas hot dip galvanized coatings normally range between 55 to considerably more than 100 microns.

Shield Technologies’ range of surface protection solutions includes the premium Spatter guard hT plus, the entry-level Spatter guard C and Spatter guard Nozzle gel. Shield

CEO, wayne holt explains that Spatter guard hT plus is a high quality liquid product that creates a heat absorbing film barrier to protect weld surfaces from weld spatter in high temperature applications.

"The product creates a double action protective film preventing adherence of weld spatter in high temperature applications by cooling down the particle before it can fuse with the material. It is ideally suited to carbon steels, stainless steels, 3CR12 and aluminium, and can be used in gas metal arc welding, flux cored arc welding and shielded metal arc welding processes."

Holt highlights the fact that one of the most important benefits of Spatter guard is the fact that it is entirely silicon free. "Most products in the local market are silicon based, which proves to be a challenge during the painting or powdering process, due to the fact that when the silicon is exposed to high temperatures, it creates a glass-like silicate on the weld surface also known as silicon islands."

according to holt, these silicon islands either chip away during painting process, causing an uneven coating, or in the worst case scenario, contaminate the primer bath. "If they fall into a primer bath, the entire batch will have to be discarded, and this could cost a company millions of Rand. what's more, silicon is hazardous to the health of workers, who very often suffer from serious lung diseases from prolonged exposure. Spatter guard entirely eliminates this health risk.

a further concern around safety when using aerosols is the risk of fire or explosion due to the use of propane as the propellant. we have even seen products containing dichloromethane as a solvent which is a known carcinogen," says holt.

Due to the fact that Spatter guard comes in liquid form, holt points out that it is more environmentally friendly when compared to industry standard aerosol products. "The disposal of aerosols is a major environmental issue that is also expensive to enforce. another advantage of a liquid product is that it works out to be more cost-effective per litre. This is due to the fact that aerosols are typically comprised of around 25 per cent atomised propellant, such as propane, which is discharged into the atmosphere when utilised," he continues.

holt notes that the entry level Spatter guard C can be used in similar applications to the premium Spatter guard hT plus, only at lower operating temperatures. "Spatter guard C is designed for the same applications, only at significantly lower welding temperatures. These applications include truck and trailer, automotive, transformer, agricultural, fabrication and armoured carriers."

further, holt points out that Spatter guard Nozzle gel, which is a mineral oil based wax, can be used to prevent spatter build up on the tip of the welding torch.

"On the welding torch, there is a copper contact tip and a wire that comes through it, which both become exceptionally hot during welding, thereby generating spatter. These spatter particles stick to the nozzle and tip and block the gas flow through the nozzle," holt continues.

Shield Technologies, a specialist distributor of products designed specifically for welding and industrial applications, can assist companies in dramatically improving welding efficiencies

through its range of innovative Spatter Guard products.

In these situations, the welder then has to clean the spatter away using a file or other abrasive tools. This process wears the nozzle out and ultimately decreases its lifespan. "Spatter guard Nozzle gel is simply pushed into the tip of the nozzle when it is hot. It then melts, forming a protective film, thereby preventing the unnecessary build up of spatter, hence improving productivity and ensuring product quality" he adds.

Shield has exclusive patents on its entire range of Spatter guard products, which are all manufactured entirely in house.

The company is one of Sa’s most experienced Solar pv providers, operating throughout sub-Saharan africa and Romano elaborates that his company’s pv systems enable

its clients to generate electricity at a lower cost than purchasing from their utility.

pv stands for ‘photovoltaic’ and Solar pv systems use solar panels to convert sunlight into electricity. Solar pv is therefore a renewable energy technology and is typically installed on rooftops, carports or on the ground. a Solar pv system is made up of one or more solar panels, one or more DC to aC power converters (inverters), a racking system that holds the solar panels and electrical interconnections. Optionally, it may include a battery system and charge controller, to provide energy security where there is no electricity grid or during power black-outs. “In these instances, Solar pv is far more economical and greener than diesel generators,” adds Romano.

The Romano group was recently awarded the engineering, procurement and construction (EpC) contract for a 360 kilowatts peak (kwp) pv system to be installed on the roof of Eskom’s Megawatt Head Office in Johannesburg, South Africa.

Eskom is the country’s electricity public utility company and is the largest producer of electricity in africa.

“we are very proud to be involved with this prestigious project, which we understand was awarded on the basis of our technical capability and track record, as well as the cost-effectiveness of our offer. This will push our installed capacity of rooftop pv projects to more than a megawatt, which is not too bad as South africa’s pv industry is still in its infancy,” continues Romano.

So far in 2013, the Romano group has commissioned four rooftop pv projects in South africa: in Cape Town 300kwp and 10kwp, and in Johannesburg 35kwp and 10kwp. Most of the Solar pv systems provided by the company are grid-tied systems, meaning that they are connected to either the client side or the utility side of the on-site electrical sub-station. In the former case, the electricity generated is used on the site by the client. In the latter case, the electricity generated is exported to the national or municipal electricity grid.

“The cost of Solar PV technology, solar panels in particular, has dropped dramatically over recent years, while electricity tariffs have risen steeply relative to inflation, and this is expected to continue for several years to come – and because Solar PV systems are

designed to last more than 25 years, the technology has become more affordable than ever as an alternative energy source,” says Alexi Romano, CEO at the Romano Group.

28

alexi Romano is also the chairperson of the South african photovoltaic Industry association’s (SapvIa) Rooftop pv sub-committee, whose purpose and aims are: to create a sustainable rooftop pv industry that benefits all South Africans; promote an ethical, sustainable and environmentally-friendly industry; set standards for the industry; influence government and municipalities to support the industry; and finally to create awareness in the market of the benefits of own-use pv.

“South africa is among the highest carbon polluters in the world and yet the country has one of the richest solar resources. Investing in proven Solar pv technology is both beneficial to the environment and a great hedge against rapidly rising electricity tariffs. a Solar pv system sized to a client’s daytime electricity load will typically achieve a payback of between 4 and 6 years, after which period the electricity generated by the system is free, and because Solar pv systems are designed to have a serviceable life of at least 25 years, this translates to a massive reduction in your future electricity costs,” Romano concluded.

The first of the range of plant being introduced is the SpS712 roof tiling machine, manufactured by Swedish-based roof tile expert aBECE, which was developed

specifically for the unique African market as part of a joint effort between the two companies, notes pMSa Marketing and Sales Manager, Quintin Booysen.

"Special considerations had to be taken into account, especially with regards to low skill levels, climate and specific requirements in africa. as a result, the SpS712 is equipped with special features, such as a dual stop/start function, which requires the operator to use both hands to start or stop the machine, thereby ensuring that hands are out of harm’s way at all times," he explains.

In order to ensure ease of maintenance and cleaning, Booysen points out that the extrusion head of the machine flips upwards. "The SpS712 roof tiling machine is also easily repairable, as all working parts are easily accessible and do not require any special tooling to remove parts," he adds.

The SpS712 roof tiling machine makes use of an aluminium palette to shape the tiles, and is capable producing between 3 000 and 5 000 tiles per nine-hour shift, depending on plant configuration."This machine is a baseline model, designed for small to medium sized businesses," says Booysen. "If production demands increase, however, the machine can be shifted into ridge production to produce the ridges that join roof tiles at the top of the roof, and then expand the main plant with a higher capacity machine."

although the SpS712 roof tiling machine was initially manufactured by aBECE in Sweden, Booysen indicates that pMSa will manufacture the model locally according to demand. “PMSA identified a gap in the local and Southern African market for roof tiling technology and expertise. having developed a tried and trusted reputation as a supplier of world class equipment and solutions for concrete product manufacturers in Africa, I am confident that the SPS712 roof tiling machine and SpS range of plants will complement our existing range, and add further value to our overall offering."

Pan Mixers South Africa (PMSA), the largest supplier of concrete brick, block and paving making machinery and technology in Africa, has extended its offering to the local industry after introducing a new range of concrete roof tiling machines into the

Southern African market in April 2013.

30

The relationship between aBECE and pMSa dates back to 2005, and Booysen reveals that the two companies decided to form a strategic partnership. "In addition to introducing the purpose built SpS712 machine to the local market, pMSa will also offer the full range of aBECE associated machinery and technology as part of the strategic partnership."

aBECE area manager fredrik Toftemo highlights the fact that the partnership with pMSa will help to ensure that the company expands its geographical footprint across africa. “I see tremendous growth opportunity for this machine in africa, especially with regards to the rapidly growing cement industry, in addition to the various government infrastructure projects planned in South africa and beyond. By working closely with an established partner such as pMSa, we can ensure that we remain at the forefront of a market that has unlimited potential."

looking ahead, Booysen is optimistic of the future outlook. "pMSa is constantly expanding its range of products in-house, and through strategic partnerships such as this one with aBECE, we plan to keep track of the market’s needs as it grows over the next few years, and to develop products and machinery to suit those needs,” he concludes.

Says, Alwyn Cronjé Jnr., National Sales Manager for Rayal, “Market research indicated that although the ‘Tuscan look and feel’ dominated roof design for so many years, the new generation South african architects and homeowners are ready for new, innovative and creative ideas that will stretch the imagination beyond style and comfort in roof covering materials and design.”

he continues, “This product has proven itself in Europe and the East alike with its quality, fresh colours, porcelain finish and affordability and is now manufactured by Rayal in South africa. The product has already brought excitement to smaller roof applications, specifically for the entry-level and low-cost residential markets.” Cronjé Jnr. continues to say that the product gives character, charm and definition to the sharpness of these smaller roofs.

Nowadays, porcelain tiles are more popular because of their unique advantages. Porcelain tiles are fully vitrified, glazed or unglazed and can be made using a white or coloured ceramic body composed of a mix of clays and feldspars.

They are shaped by pressing a powdered body and the fired product has water absorption rate of less than 0.5% (ISO 10545-3).

glazEd tIlEs

“glazed porcelain tiles appeared in the second half of the 1990s and these contributed to advancement in the overall quality of porcelain production,” says Cronjé. A key practical implication is that the low porosity of porcelain tiles makes them frost-resistant. In addition, the higher quality body composition and resultant surface enables the use of a minimal amount of glaze (enough to close surface pores).

Cronjé Jnr. Concludes, “It is clear from market reaction that the Rayal new generation porcelain roof tiles are setting new standards beyond style and comfort.”

The solution to the school’s problem of excessive and expensive electricity consumption by air-conditioners lay in reducing reliance on active temperature control

interventions during seasonal temperature extremes and also preparing for possible load shedding – very much part of the South african horizon, given the cutbacks on Eskom's planned infrastructure upgrade spend this year as the grid nears capacity.

The Durbanville school case history file is typical of many public infrastructure buildings in South africa. Originally built during times of cheap power supply, scant attention was given to thermal/energy efficient building under tight construction budgets.

Increasingly specified within the built environment, Eco-Insulation is ideally suited to working public buildings due to the following:

• minimum consideration of construction schedules: "a turnkey service in all sense of the word – delivery on time and on budget," says Richard Ellis, general manager of Eco-Insulation and principal installer in the Cape Town area.

• Convenience: The Eco-Insulation team worked in the background at the Durbanville preparatory School whilst classes were in session.

• minimal impact and disruption to roof infrastructure: Single tiles or roof sheets are removed to facilitate access, leaving minimal potential for damage. Delivery of Eco-Insulation in situ is via a simple pneumatic hose. From there, the product flows over the surface of the ceiling very efficiently and evenly distributes itself, sealing off the area close to 100%. The hose is fed from a pump that is operated from outside the building. Once installed, the material mats together and does not migrate around the roof space.

Ellis explains that decisions for retrofitting of energy efficiency measures are currently driven by the occupants/tenants/users of the building, since they are the most immediately affected by energy cost increases. They are also the most affected by disruptions of any kind.

an important part of Eco-Insulation's service is the removal and approved disposal of any existing non-performing insulation product from the roof space. Eco-Insulation has an approved method of removing and disposing of noxious glass fibre material, which traditionally presents a huge headache for property owners, due to the fact that many established municipal waste facilities will not accept hazardous waste.

"The insulation industry needs to provide easy, cost-effective solutions to retrofitting, and argue the case better for passive temperature control. In our case, Eco-Insulation is definitely the more cost-effective solution. as far as housing projects are concerned, our promise is energy efficient, on time and on budget. we save the project manager and ultimately the property owner money – and we are SABS-approved!" says Ellis.

falling objects from heights can cause serious harm or even kill workers below and can also damage property. The edges of working platforms must be protected with toe boards and with adequate double handrails.

Toe boards are to prevent materials, tools and equipment from being kicked off and falling from the platform.

Stairs found on access scaffolds must have correctly secured and positioned handrails. Only use access ladders that are secured and positioned on the inside of the access scaffold. Make sure that the platforms these access ladders lead up to are fitted with trap doors and be sure to keep trapdoors closed at all times. It is recommended to place ladders away from other trap door openings.

Sufficient, safe or unsafe signs must be strategically positioned on the scaffold. The date and time of last inspection must be recorded on the reverse of the scaffold tag.

as with most other scaffolds it is extremely important that the platforms from which you are working have sufficient platform boards, covering the entire platform, as well as the edges being protected with toe boards and adequate double handrails.

Remember: It is important to never climb on the outsides of any type of scaffolding. If you do you can fall and be killed or end up permanently disabled. Use only the stairs and access ladders that are secured and positioned correctly. This will ensure your safety while working on freestanding scaffolds.ladders leading to higher scaffold levels must be placed away from each other and platforms must have trap doors in place and these must always be kept closed. Ensure that safe or unsafe signs are placed on the scaffold – these will indicated whether or not it is safe to use the scaffold.

Check the reverse of the scaffold tag for information such as the date and time of last inspection. The scaffold inspector is responsible for the inspection and recording of this information.a scaffold can become very unstable is the height to base ratio exceeds 3:1. This means it can never be higher than three times its narrowest base side.

This scaffold must at all times comply with OhS act and Regulations, SaNS 10085 and the design criteria.

moBIlE scaFFold:

Due to the nature of mobile scaffolds, it is very important that mobile scaffolds are only used on sound and stable bases or where the floor conditions are adequate. Mobile scaffolds follow the same principles and requirements as freestanding and access scaffolds with regards to bracing, platform boards, handrails, toe boards, access ladders and trapdoors.

• Check that there is adequate bracing installed.• Check that there are sufficient platform boards in place.• Check the edges are protected with toe boards and

adequate double handrails.• In addition, an adequate number of access ladders must be

positioned and secured correctly.

working platform accessed by ladders must have trapdoors installed and these must be closed after use. also, check and make sure all ladders are positioned away from trapdoor openings. always check the scaffold tag before using the scaffold. It will tell you whether it is safe or unsafe to use.

Make sure the wheels or swivels are in good condition, fitted in position and suitable for the job.

Check that the brakes are in good condition. This is important, as a mobile scaffold should never move or be moved whilst persons are still on it; persons must first get off and then it may be repositioned to avoid any ‘out of control’ situations.

Before using a mobile scaffold it is essential to make sure it is reasonably level, stable and its height is no more than three times the narrowest base.

The installation and use of mobile scaffolds must comply with the OhS act and Regulations, SaNS 10085 and the design criteria.

sUspENdEd scaFFolds:

Suspended scaffolds require adequate out rigging as well as suitable components that are secured and correctly positioned. platform handrails must be of a substantial and correct height, secured, and installed around all edges of the scaffold.A valid test certificate must be available on site for the corresponding suspended scaffold.

swINg scaFFold:

Swing scaffolding also requires adequate out rigging. Make sure the out rigging complies with the scaffold design. The condition of the steel wire ropes must be checked and any potential defects identified.

winches, cable attachments and brakes must all be checked to be in good working condition and the corresponding test certificate must be available. Electrical controls on the scaffold must be accessible and functional at all times and all cables must be protected and in good condition.

Both suspended and swing scaffoldings must comply with the OhS act and Regulations, SaNS 10085 and the design criteria. all other scaffolds fall under the special scaffolds category. The following requirements must be met when erecting a special scaffold: The cantilever, jib and truss-out must be installed as per the design; scaffold material must be in good condition and adequate for the design; and there must be suitable, sufficient and substantial access to and from the scaffold.

The centre, which is being developed by the Moolman group, together with two polokwane-based businessmen, Jaco Nel and Sam Mabotja, is scheduled to open in six

months’ time.

already, some 90% of the space at Seshego Circle has been let – an indication of just how high the demand is for a quality retail centre Seshego. The centre will serve the local Seshego community, as well as provide a shopping amenity for some of the more outlying areas such as Makgofe, Mobokele and perskebult.

anchor tenants in the centre include Shoprite and Cambridge (a Massmart-owned supermarket chain). National retailers, such as Jet, Edgars active, pep, Total Sport, Exact, Markhams, Truworths, Identity, Mr. price and Rage have also taken space in the centre, providing shoppers with the kind of experience they would expect to find at most modern shopping centres. The likes of King pie, Debonairs, the fish & Chip Company and a KfC drive-through will provide shoppers with places to have a bite while they shop. Standard Bank, Nedbank, Capitec and african Bank will also have a presence in the mall as the need for banking facilities is high.

Seshego Circle is located at the junction of Nelson Mandela and polokwane Drive – the two main arterial roads connecting Seshego with polokwane and the north.

The development of the centre is very much in keeping with the move by developers such as the Moolman group to identify under-serviced areas – particularly peri-urban areas and former township areas – and meet the retail needs of local residents who often have little alternative but to travel long distances to do their monthly and bulk shopping. The development will also provide a number of temporary and permanent jobs to people in the area.

as far as possible, every effort is being made to ensure that people from the local community are being employed on the project. The main contractor, CMC Construction, is a polokwane-based company, and most of its employees come from the Seshego area.

as water resources decline and water quality and reliability of supply become suspect, more and more people and companies are looking at alternative sources of supply.

Rainwater harvesting is not a new concept, but because municipal water has been plentiful and of good quality, the modern generation has forgotten that many of our forefathers only had rainwater as a source of drinking water. we now have to rediscover the process of harvesting rainwater and apply modern technology and sophistication to supplement the dwindling water supply.

Rainwater has a number of positive and negative qualities that must be taken into consideration when deciding on a rainwater harvesting system. Before hitting any surface, rainwater it is virtually pure, contains no chlorine, is slightly acidic, contains very few trace elements, and is fantastic for human consumption but bad for certain metals if it is not treated correctly.

putting rainwater harvesting opportunities into perspective:

an average house with a surface area of 220m2 in a high rainfall area like Durban can harvest sufficient rainwater for the household to make it completely independent from the municipal supply for nine months of the year. The harvested water is treated and converted into potable water and supplied straight back into the house, as if it were municipal water.

a large warehouse with a surface area in excess of 4000m2 will allow the occupant to harvest enough water to support a small community, or keep a small factory independent from municipal water for an extended period of time.

Does this mean everybody should now buy a tank, modify their gutters, and start collecting rainwater? It might be the easy option, but effective rainwater harvesting requires good planning, design and construction principles for it to be a lasting water source and a good investment.

It was recently reported that South Africa, with half the global average rainfall, will run out of water as soon as 2015. Specialists estimate that South Africa will be short of three billion cubic metres of water by 2030,

which amounts to 17% of expected demand. Article supplied by Tizagenix

46

There are a number of critical factors to take into account when one considers setting up a rain harvesting system. The first is to look at the rainfall in the area; the higher and more frequent the rainfall, the greater the opportunity for water harvesting.

a second consideration is to look at the surface area where the water will be harvested. If one wants to harvest potable water, contamination should be minimized in order to reduce the treatment cost. The more contaminated the harvested water is, the greater the cost of treatment and installation required to get the water to a potable standard.

Many systems are designed to only use rainwater for non-potable applications, like washing, flushing of toilets, and supply of water to process equipment for cooling. a key success factor is to make sure that the water is consumed effectively, so one doesn’t just end up with tanks full of water that will not be consumed.

Once the rainwater harvesting area and level of potential consumption have been clearly identified, the transport system (gutters) and a good storage area must be designed. This is one of the biggest cost elements for an effective system and generally storage areas are always undersized, resulting in the loss of good rainwater during periods of good rain.

The treatment of rainwater will depend on the use, either for potable or non-potable applications. various water treatment principles can be applied, but if it the water is to be used for drinking, it is critical that in the last phase of treatment, the correct sanitization process is applied. This can vary from chlorination, ozonation, Uv light radiation or ultra-filtration. The potable water must meet the SaBS standards for potable water once treated.

generally the most cost-effective systems are conceptualised in the design phase of the building. Roofing design, material selection and guttering are critical elements that need to be considered and incorporated into the design of the structure. at the same time, it is often important that the installation is also aesthetically pleasing.

Existing building and structures can be converted to harvest rainwater effectively, and with a bit of creative design, changes to the roof and guttering, together with a professional rainwater harvesting company, the building’s roof can become an excellent surface for collecting rainwater.

Rainwater harvesting and water conservation should be on the agenda of every company or homeowner.

It is a cost-effective investment that can make a significant financial difference and also offers peace of mind for those environmentally concerned.

SS Profiling manufactures IBR, Widespan, Corrugated Iron, lipped Channel, Slit Strip, SS Tile and many other steel roofing-related products.

The SS Tile is an aesthetically pleasing product and solves many of the problems associated with clay and concrete tiles. It is an in-line pressed profile which can be produced in any length, just like an ordinary roof-sheet. It also has a standard cover-width of 762mm, which is similar to that of Corrugated Iron and widespan. It is not a singular steel pressed tile that has to be fitted individually, but it is fixed to the purlins, just like ordinary roof-sheeting and is used in upmarket estates, as well as on RDP housing. SS Profiling, on request, sends a team of experts to teach the contractors how to install the product properly, even though it is fairly simple compared to other pressed-tile products. This is often done on large RDp housing projects. with regards to upmarket installation, most contractors have managed proper installation at their first attempt.

SS Profiling’s slitting facility enables them to offer Slit Strip to a wide range of industries, as well as for their own in-house consumption. galvanised Slit Strip in thin and thicker gauges are being produced to narrow tolerances to suit customer needs.

lipped Channel and purlins are manufactured from hot Rolled, whereafter it can be painted on request. pre-galvanised lipped Channel and purlins are also popular, especially in the coastal areas.

Says Theunis Duvenage, CEO of SS Profiling, “To plough back capital and invest in human resources is the key to success in a highly competitive environment. your product simply has to be better, cost-effective and you need to deliver on time.”

SS Profiling has been actively involved in various forms of art, namely photography, song-writing and graphic design. This involvement is different from regular corporate social responsibility; it is not the all-familiar sponsorship approach, but personal, active participation.

Something important to most South africans is the slaughter of our rhino population, and, true to the spirit of the people of SS Profiling, they got involved, not by sponsoring money, but by creating awareness by photographing the subjects and designing a complimentary carry bag and bumper sticker that will be released, together with a children’s book, by the renowned author, Nico Moolman, in coming months.

In support of the arts, SS Profiling has recently released an Afrikaans and English CD, called ‘Just you.’ all of the songs on the album were written by an employee and performed by Bianca le grange, a former Idols finalist. The photography and some of the filming work, which is also included in the CD and video releases, were also produced by the people of SS Profiling. The videos can be viewed via the following links:http://www.youtube.com/watch?v=xj7ihQ0htzohttp://www.youtube.com/watch?v=kaBmb_QDpg0&feature=youtu.be SS Profiling will also be releasing a calendar soon, which will run from July 2013 to June 2014. The calendar comprises a unique artwork that combines graphic design and photography to teach the basics in astronomy. The principle represents a celestial photograph whereafter an overlay explains the different star-signs and honours the stellar and planetary constellations that are the ancient source of the zinc that we use in our industry today.

Datlink’s products are manufactured using recycled polyester and were the first insulation products to be verified 'green' by Eco-Specifier with no reservations.

Ownership of Datlink Insulation & acoustics changed in february 2013, with the goal of providing an upgraded insulation and roofing solution to all sectors of the industry. The four new owners of Datlink Insulation & acoustics have over 100 years of accumulative experience in the construction, project management, manufacturing and financial industries.

Recent legislation stipulates better thermal solutions within both heavily and lightly populated working and living environments and covers the full range from domestic through to industrial buildings. Recent educational drives, seminars and courses have helped make the legislation more understandable for both end-users and specifiers, but the knowledge of which products are the best ‘fit for purpose’ within this legislation still requires continuous input.

Datlink prides itself on supplying this input to professional architects and engineers across the construction and supply industry and to the end-user.

Just as important as choosing the correct product is identifying the correct details and fixing methods that ensure that the product choice is installed according to the specifications. The Datlink team is dedicated to making sure that the correct products are used in accordance with the client’s brief, the legislation and the allocated budget. This ensures that the client ultimately benefits from a ‘fit for purpose’ solution which conforms to best practice for the occupancy of the building.

MD of Datlink Insulation & acoustics, Craig fussell, has one major goal with regards to their ‘new’ company; that is to make sure that the company supplies both a full technical design support service at design stage, followed up by an efficient and cost-effective supply of the suitably specified material. This hands-on approach ensures that the client actually receives their originally designed ‘fit for purpose’ environment and avoids unnecessary disappointment if the original (correct) specification was changed without their full understanding of the implications.

Datlink Insulation & Acoustics has been supplying insulating and acoustic material for many years with successfully competed projects such as Gautrain, Cape Town

International Airport, Karl Bremmer Hospital, V & A Waterfront Clock Tower, Christel House and Herzlia Schools, each with a very specific design and specification need.

JUNE 201352

Recent examples of where good upfront design has resulted in clients enjoying the correct environment within their buildings are:

• V & A Waterfront Clock Tower, which benefitted from using over purlin ThermocousTex fibre, resulting in both a substantial reduction in rain noise and achieving the legislated R-value of 3.7.

• Christel House & Herzlia Schools benefitted from using exposed ThermocousTex plasterboard within the classroom. The most important benefit in this application (over and above the insulation benefit) is the substantial noise reduction from outside rain and the sound absorption within the classroom, both of which create a preferential teaching and learning environment.

a.b.e., part of the Chryso Southern africa group, signed an agreement with the Italian company, index, the world’s leading producer of bitumen membranes, in 1966.

lance anderson, a.b.e.’s Brand Manager: Waterproofing, says the two million rolls of index rolls would, in extent, have been sufficient to cover nearly 20 million square metres of waterproofing on a wide variety of structures ranging from domestic dwellings, commercial and industrial premises, as well as dams and reservoirs. “The bulk of the index waterproofing applications for which a.b.e. supplied the products took place in South africa and SaDC countries with a portion also used in other parts of the african continent,” he states.

“as partners with index, a.b.e. has access to on-going research and development to produce world class products that meet the needs of our customers and provide top performance for exceptionally long period in demanding environments.”

The index range distributed by a.b.e. covers a wide range of products that include:

• index defend antiradice (anti-root) p – a polymer-bitumen, elasto-plastomeric waterproofing membrane with anti-root additive, reinforced with a non-woven single strand spun bond extruded polyester fabric designed for waterproofing planter boxes and roof gardens;

• index testudo – elasto-plastomeric polymer-bitumen waterproofing membrane designed for waterproofing car parking decks, bridges, viaducts, etc. under hot premix asphalt, water works, foundations, below ground tanking, and industrial and commercial applications that conventional membranes have difficulty waterproofing;

• index fidia P & MS – polymer bitumen waterproofing membranes designed for continuous waterproofing on flat concrete decks, foundations, and tunnels;

• index helasta p4 - polyester 4mm thermoplastic rubber waterproofing membranes with high elasticity for waterproofing construction joints on decks;

• index indextene – self-adhesive bituminous membrane designed to waterproof structures where the use of open flame is prohibited by means of a high adhesive bonding strength based on the ‘peel-and-stick’ method;

• index selftene – self-adhesive waterproofing elastomeric membrane in polymer-bitumen with the lower face coated with a self-adhesive elastomeric mass for waterproofing structures where flaked flame is prohibited;

• index unigum biarmato & MS – reinforced polymer-bitumen waterproofing membranes ideally suited for waterproofing applications in hot climatic regions on flat concrete decks, tanking, tunnels, dams, etc.;

• index vIS p & vis p – reinforced plastomeric polymer-bitumen waterproofing membranes for general use.

Many of the index product variants are offered in a mineral slate (MS) version, which reduces long-term maintenance costs because of its resistance to Uv radiation.

index waterproofing membranes are manufactured by Index Construction products Spa of Italy, the largest producer of modified reinforced membranes in the world with a product range covering every aspect of the building and construction industries. The company – which operates in over 90 countries – has many decades of expertise in developing specific use bituminous waterproofing membranes and systems. Its products have been independently tested by over 25 respected testing institutions worldwide and conform to the most stringent global standards.

“index also offers insurance-backed product guarantees on all the membranes in its range. Technical solutions to installations are offered through a.b.e. Technical Representatives who are trained in all aspects of index/a.b.e. products. a.b.e. has had a long association with index and will continue to build the brand in South africa through the launch of new products in the index range later this year,” anderson adds.

ITW BUILDEX® THE INNOVATORSCan you trust roof fasteners imported into the South African market?ITW have been in business over 90 years & invented the self drilling Tek’s point used Worldwide. We were the first to

develop ISO Class 3, 4 and now the new Class 5 coating to combat corrosive environments . First to test in Outdoor “ Real World ” corrosive environments. First with Shank Guard® & Hi Grip® features . First to use Non Conductive EPDM seals &

First to give Warranties to roof owners.

Buildex® as the market innovator have been “ Real World ” testing since 1994 as part of AS3566-2002 section B not lab testing as that does not replicate the combined corrosive elements a steel building is subjected to such as Ultra-Violet light, Humidity, Salt spray, Chemicals, Galvanic cell corrosion from dis-similar metals in contact and the accelerating effect of high temperatures.

Buildex screws often last over 4000 hours in lab salt spray tests but our outdoor tests prove that other brands may not pass the realistic more harsh outdoor test as the samples of Asian made screws, (left) show after just 16 months of exposure.

Using proven Buildex® screws is cheap insurance against failure. Can you trust the others?The cost difference between cheap and Buildex® fasteners for an average house can be just R700. Compared to the total cost of an installed roof this is very cheap insuranceand assurance for the roof owner and installer alike.
