Stressline Limited manufactures a wide range of structural building products for domestic and commercial sectors. Stressline is the fi rst choice for builders, contractors & specifi ers across the UK because of its ability to deliver high quality products on time and at the right price, ensuring projects are not disrupted and work is completed on time.

Stressline also supply direct to site or through a supply chain of merchants across the country, making sure their products are always highly accessible. Stressline’s customers choose them over other structural product manufacturers because of the promise to always be competitive on price, the mixed order delivery capabilities and the high quality service.

Stressline’s in-house technical and manufacturing departments have worked hard over the last 12 months to deliver an extended range of steel lintels. The new lintel guide clearly lays out the extended standard range of steel lintels, and for the fi rst time the prestressed concrete lintel range, allowing the customer the utmost fl exibility and choice to satisfy their lintel requirements.

This extended steel lintel range perfectly compliments our other structural building products.

We manufacture a complete range of prestressed concrete products in addition to the prestressed concrete lintels; including fl ooring beams (suitable for concrete or insulation infi ll), hollowcore fl ooring, and walling panels. Precast items available include padstones, stairfl ights and landing slabs, although our extensive design and manufacturing resource enables special projects to be produced cost effectively. Our non structural range of products includes fencing and landscape walling products.

service DeLiverY OUR COMMITMENT TO YOUsALes & sUPPOrTOur area sales managers and sales technicians are able to assist you with your specification needs. Whether advice is needed for a single lintel, or a comprehensive take off and pricing schedule for a multi dwelling development, our team is here to help.

The brochure and website outline our ranges and offer tools to assist your selection.

In addition, our unique ability to manufacture a range of structural building components offers the specifier and the buyer a complete solution for structural flooring (both beam and hollowcore), steel and concrete lintels and structural precast products, including padstones, staircases and landings.

Our flexible design and manufacturing facilities enable your “special” lintel requirements to be produced quickly and efficiently.

OUr PrODUcTsOur comprehensive range of standard steel and concrete lintels offers design capability for all circumstances, designed to the relevant BS EN standards and with the reassurance of BS EN ISO: 9001 (2008) management standard.

The cavity lintel range is supplied with captive insulation to ensure that it is not displaced. The fabricated range is manufactured with a proven non-welded method creating a secure connection that has not compromised the galvanised protection.

Our range of prestressed concrete lintels is manufactured using machinery and processes designed by our own engineers. This has enabled the maximum strength to section available, whilst producing high volumes of consistent quality products.

DeLiverYAll our products are delivered on flat bed articulated or rigid lorries, with the option of either self offload or crane offload. Depending on the customer’s requirements both steel and concrete lintels are packaged in stock packs or in consignment loads (with the option of house plots and locations marked on the product).

As we are located centrally we are able to supply all our standard products nationally, with delivery typically three to eight working days.

OUr PrOmiseStressline understand the day-to-day challenges you face on a building site and the importance of working with a supplier you can trust. Our promise is simple – to deliver competitively priced products, on time, to the required specification.

AccreDiTATiOnsStressline has an on-going commitment to improving both product and management systems; • 1989: BSI Quality Assurance Accreditation

to ISO 9001• 2003: BS EN ISO 9001:2000 • 2009: ISO 9001:2008

envirOnmenTAL AnD sUsTAinAbiLiTY We recognise our responsibilities to the environment. We are committed to developing, implementing and reviewing our management and operational policies and procedures to minimise our environmental impact. Our IMS includes all our compliance policies and achievement targets.

From our ongoing environmental and sustainability commitments we have continued to achieve significant reductions in our impact as manufacturers and distributors. One major environmental benefit shared with our existing customers is the ability to source our complete range of products and for them to be delivered as a mixed load on one vehicle, instead of separate deliveries which creates wasteful and unnecessary movements.

ALWAYS CHECK LOADINGS AGAINST OUR LOAD-SPAN TABLE

insTALLATiOn nOTes See page 46 for general installation notes.

Additional requirements for composite extra Heavy Duty (cXHD) lintels• Ensure that the inner leaf channel is fi lled with

well cured masonry before work proceeds over. Masonry needs to be built tightly against the vertical section of the channel and a mortar joint added to the top of masonry, so that the loads from units above are spread evenly over the inner fl ange of the lintel.

• Composite lintels should be adequately propped during construction, at maximum 1.2 metre centres. Props should not be removed until the mortar has cured.

ADvAnTAGes• Easy to install and suitable for a variety of

applications• Galvanised coating ensures durability/longevity• Built-in plaster key: perforated base plate to

Additional requirements for rs and rsc type lintels • Lintels must be laterally restrained and

adequately propped during construction at maximum 1.2 metre centres. Props should not be removed until the mortar has cured.

• Minimum of 200mm bearing is required• RSC type lintels - channel MUST be fi lled with

masonry before the work proceeds over and needs to be built tightly against the vertical section of the channel using good quality, well bonded mortar joints.

mATeriAL Lintels are manufactured using 203x133x30kg/m UB or 230x90x32.2kg/m RSC with a 6mm welded bottom plate to BS EN 10025 – 2: 2004 of steel grade S275.

FinisHinGLintels are coated as standard in a red-oxide paint. However, they can be supplied, at extra cost, with a galvanised fi nish.

ADvAnTAGes• Available in 50mm increments with a maximum

length of 6600mm• Can suit a variety of cavity wall constructions• Availability 7-8 working days (red oxide fi nish)

Additional requirements for (TF) type lintels• To avoid excessive defl ection and possible

twisting, lintels should be secured laterally with restraining clips and should be adequately propped during construction at maximum 1.2 meter centres. Props can be removed after the mortar has cured.

• A tight fi tting timber batten (supplied by others) should be placed at mid span to help prevent any lateral defl ection.

• Restraining clips to be spaced at maximum 500mm centres, starting from mid span. Clips must be nailed to the timber frame.

ADvAnTAGes• Easy to install and suitable for a variety of cavity

walls• Galvanised coating ensures durability/longevity• Supplied with appropriate number of restraining

APPLicATiOnGalvanised steel box lintels are designed for use in 200-215mm solid walls and are available in three different designs: box with a lip/toe (SL200 BOX), inverted ‘T’ section (SL200 T) or back to back channel (SL200 CH).Designed to support:• Concrete fl oor loads• Tile hanging• Masonry loads• Timber fl oor joists• Attic truss loads and/or roof trusses• Point loads for example compound trusses,

steel beams etc• SL200 BOX is designed to support 19:1 load ratio• SL200 CH and SL200 ‘T’ are designed to support

1:1 load ratio



Additional requirements for sL200 cH and sL200 ‘T’ type lintels:• To avoid excessive defl ection and possible

twisting, lintels should be adequately propped during construction at maximum 1.2 metre centres. Props should only be removed after the mortar has cured.

• To achieve stated loading fi gures, SL200 CH lintels MUST be fi lled with well cured masonry before work proceeds over.

ADvAnTAGes• Easy to install• Inverted ‘T’ and back to back channel sections

can be used to carry fair facing brick walls on both sides

• Can be used in tile-hanging external walls• Galvanised coating ensures durability/longevity• Suitable for use under various loading

APPLicATiOnDesigned to support:• Masonry loads• Uniformly distributed timber fl oor loads• Uniformly distributed roof loads • Concrete fl oor loads• Attic truss loads• Point loads for example compound trusses,

steel beams etc



Additional requirements for lintels supporting concrete fl oor units• Check that the correct lintel has been installed.• Minimum recommended lintel depth is

140mm in order to absorb the shock loading of concrete fl oor. Precast fl ooring units should be laid on a mortar bed across the whole wall width and should not be dragged over supports.


applications: internal partitions, external cavity walls, garages, over services.

• We offer a wide range of lintels from 100 x 65 through to 220 x 140 catering for every circumstance, with both ‘Universal’ and ‘Hi-Strength’ derivatives where required.

• If required, Stressline can schedule and deliver in house plots.

imPOrTAnT nOTes• The loading fi gures published in the load-

span tables represent the Uniform Distributed Serviceable Load (UDL) in kN/m which can be supported by the lintel without the provision of structural brickwork/blockwork over. This is known as Independent Design.

• Lintel lengths shown greyed out within the load-span table are available in longer lengths than the maximum clear span would normally allow. These longer lengths lintels should be used over a series of openings (with intermediate supports) NOT exceeding the maximum clear span and NOT simply supported at each end (i.e. all 65mm/70mm deep lintels must not clear span more than 1800mm).

MATERIAL SPECIFICATIONStressline standard galvanised steel lintels are manufactured from DX51D grade steel to BS EN 10327: 2004, with a zinc coating type Z600, giving a minimum zinc coating of 600g/m² including both sides. All cut edges are treated with corrosion resistant paint. RS and RSC lintels are manufactured from structural steel plate of grade S275 to BS EN 10025-2: 2004.

INSULATIONLintels used in external walls are fully insulated with expanded polystyrene.

QUALITYStressline products are manufactured to the highest quality, under strict control, and comply with all relevant British

Standards. We are continually assessed by the BSI to ensure our quality assurance systems comply with BS EN ISO 9001: 2008.

COSHHProducts are considered non-hazardous to health under normal use. Material data sheets are available from our technical department upon request.

STRUCTURAL PERFORMANCEThe loadings published in the load-span tables were achieved in accordance with BS EN 845-2: 2003 and tested in accordance with BS EN 846-9: 2000. Stated fi gures represent the Total Serviceable Uniform Distributed Load (UDL) in kN.

‘CXHD’ and ‘CH’ type lintels have been tested compositely in accordance with BS EN 846-9: 2000 with the surrounding masonry built in accordance with BS 5628. The structural performance of our lintels is supported by continuous in-house testing.

Load Ratios are always expressed as inner leaf to outer leaf: 1:1 – lintels supporting masonry only 3:1 – lintels supporting masonry and timber fl oors 5:1 – lintels supporting concrete fl oors 19:1 – lintels for eaves applications

RECOMMENDATIONS FOR INSTALLATION • Minimum recommended bearing length is

150mm. The lintel should be bedded on mortar and levelled both along the lintel and across its width. Full bricks, blocks or padstones should be used as bearing areas. Do not bear lintels onto cut blocks!

• Prior to installation, the lintel should be examined carefully for any defects or signs of damage.

• All external wall lintels MUST be installed with a fl exible damp proof course (DPC) or cavity tray.

In the case of cavity walls the cavity tray should extend not less than 50mm beyond the cavity return.

• Inner and outer leaves supported by the lintels should be raised together to avoid excessive eccentricity of loading.

• Masonry must not overhang any fl ange by more than 25mm.

• Masonry above the lintel should be allowed to cure before applying fl oor or roof loads.

• Composite lintels (i.e. ‘CXHD’, ‘CH’ and ‘RSC’) should be adequately propped during construction, at maximum centres of 1.2 metres. The props should not be removed until the mortar has cured. Ensure that the composite part of the lintel (channel) is fully fi lled with well-jointed masonry and allowed to cure.

Additional recommendations for lintels supporting concrete fl oor units• Check that the correct lintel has been installed.• Avoid shock loading of lintels during the

installation of concrete fl oor units and any sideways loading while being fi tted into position. Precast fl ooring units should be laid on a mortar bed across the whole wall width and should not be dragged over supports.

If you are in doubt as to the structural performance or suitability of a lintel then please contact our Technical department before ordering/installation.

We offer a free scheduling service providing clear and concise schedules based on your working drawings (plans, elevations, sections, fl oor/roof layout, etc.). Structural calculations for local authority can be provided upon request to support our specifi cation.

We can design and manufacture ‘special’ lintels to suit a variety of innovative opening shapes and cavity wall constructions. State of the art production facilities and design expertise enable us to take an architectural idea and turn it into a functioning product.

TECHNICAL – STEEL LINTELS


sTrUcTUrAL PerFOrmAnceStressline prestressed concrete lintels are designed in accordance with BS 8110-1: 1997 with a concrete strength of 50 N/mm² or 60 N/mm² and utilizing strands to BS 5896. Lintels are manufactured to BS EN 845-2: 2003. Materials used in the manufacture of Stressline prestressed concrete lintels comply with BS EN 206-1: 2000 and BS 8500.

Lintels offer a minimum of ½ hour fi re resistance in accordance with Table 4.3 from BS 8110-2: 1985. This can be increased by additional protection as specifi ed in clause 4.2.4 from BS 8110-2: 1985.

The structural performance of our lintels is supported by continuous in-house testing.

imPOrTAnT nOTesThe 100 x 65, R15, R22 and RW22 lintels are ‘Universal’, which means that they can be turned either way round to suit the wall construction.

In accordance with good practice, 100 x 70 Hi-Strength, 140 x 65, 220 x 65 and 140 x 140 Hi-Strength lintels are stamped ‘TOP’ and this surface must be kept at uppermost at all times. Our 100 x 140 Hi-Strength lintels have a groove along the top to enable them to be differentiated from R15 ‘Universal’ lintels. In addition to this, the 100 x 70 Hi-Strength and 100 x 140 Hi-Strength lintels are sprayed with blue paint across the section at one end to avoid confusion with similar sections: 100 x 65 and R15 respectively.

QUALiTYStressline products are manufactured under strict quality control and comply with all relevant British Standards. We are

continually assessed by the BSI to ensure our quality assurance systems comply with BS EN ISO 9001: 2008.

cOsHHProducts are considered non-hazardous to health under normal use. Material data sheets are available from our technical department upon request.

recOmmenDATiOns FOr insTALLATiOn• The lintel should be bedded on mortar and

levelled both along the lintel and across its width. Full bricks, blocks or padstones should be used as bearing areas. Do NOT bear lintels onto cut blocks!

• recommended minimum bearings are:– 100mm both ends in structural openings up

to 1000mm– 150mm both ends in structural openings up

to 3000mm– 200mm both ends in structural openings greater

than 3000mm

This does not discharge the installer’s responsibility to ensure that the bearing pressures of the masonry are not exceeded.• Prior to installation, the lintel should be examined

carefully for any defects or signs of damage.• All external wall lintels MUST be installed with a

fl exible damp proof course (DPC).• Masonry must not overhang the lintel by more

than 25mm.

LiFTinG AnD sTAcKinG• When using mechanical plant, only 1 layer of units

should be lifted at a time and supported at or near ends.

• Units should be handled carefully as they will not withstand heavy blows, dropping or reverse bending.

• Lifting should be carried out with regard to weather conditions, particularly wind, adequate lifting capacity and lengths of chains.

• No lifting should be carried out over work areas.• Load weight should be checked prior to lifting.• Stacking should be the right way up on suitable

fi rm, level ground.• The bearers should be near to the ends and

vertically over each other.• Examine units (and infi ll blocks) for cracks and

damage and if present do not use.

Additional recommendations for lintels supporting concrete fl oor units• Check that the correct lintel has been installed.• Avoid shock loading of lintels during the

installation of concrete fl oor units and any sideways loading while being fi tted into position. Precast fl ooring units should be laid on a mortar bed across the whole wall width and should not be dragged over supports.
