SHU HEUNG GRATINGhttp://www.shge.co.kr


Manufacturing Process1. STRONG,

LIGHTWEIGHT

SUH HEUNG GRATING is

very strong and light in

weight. It consist of a lat-

ticework of bearing bars

and cross bars joined to

each other in a fixed con-figuration by projection

welding.

2. EXCELLENT LIGHTADMISSION AND VENTILATION

SUH HEUNG GRATING light

admission and ventilation

abilit ies are excellent

because of its large open-

ing area. It will keep thework surroundings clean

and light.

3. NON-SLIP AND SAFE

SUH HEUNG GRATING dis-

play non-slip ability in

every direction thereby

providing a safe working

surface.

4. BEAUTIFULAPPEARANCE

The latticework of bearing

bars and cross bars will

neatly match with any

types of flooring in the fac-

tory, ship, etc., and will

make a nice geometrical ensemble.

5. EASY INSTALLATIONAND REMOVAL

SUH HEUNG GRATING is

designed and manufac-

tured according to cus-

tomer s specification and

is easy to install. Because

of our grating configura-tion, it fabricate easy

removal of grating.

6. GOODMACHINABILITY

SUH HEUNG GRATING can

readily be pre-cut to the

customers specifications

just like plate, because the

bars are joined in a fixed

configuration.

7. ECONOMICAL

The price of SUH HEUNG

GRATING is very reasonable

through mass production

in our well managed plants

under careful quality-con-

trol.

8. COMFORTABLECLEANING

It is easier to clean inside

trench because SUH

HEUNG GRATING is made by

good design and careful

consideration.

ProcessSUH HEUNG GRATING have been fabricated in strict accor-

dance to N.A.A.M.M. (National Association of Architectural

Metal-Manufactures) specification and high quality governed

by our TQC system. The following is the work process:

It is important to note that when there is no lateral restraint provided by the support structure, a minimum of four clips per panel

must be used to restrain floor panels. Where larger panels are to be fixed it is advisable to use extra clips on any available intermedi-

Non Standard Requirement

S.H Gratings are manufactured in numerous combinations of bearing bar height and thickness, bearing bar pitch and cross bar pitch.

Facilities Coating By Hot-Dip-Galvanizing

Characteristics of Zinc Coating’s DurableProperty of Anti-corrosion

In the air, under the water, in the soil and even

within concrete mixtures, Hot dip galvanizing

displays magnificent and consistent anti-rust and

anti-corrosive characteristics.

Products coated by the hot zinc galvanizing method

possess ideal properties. They form an anti-rust film

for iron/steel and, is most economic when

compared to any other method of treatment as it

displays anti-rust durability against rust in the air,

under water, in the soil and concrete mixtures.

Ranging from electric power and communication

uses, such as iron-tower for power transmission

lines, electric pole and other electric power

machinery, to engineering works, architecture,

agriculture, livestock and fisheries zinc-coated

products are utillised in various fields of industry,

and thus zinc-coating has become indispensible to

our daily needs in modern life.

1. Works to Protect the skin-film:A delicate, thin film is created on the surface of the melted

zinc skin and this obstructs the process of corrosion there-

after.

2. Sacrificial Devotion to Anticorrosive:In case the surface film of zinc coating is damaged for any

reason, the iron/steel corrosive effect will be kept under

control, due to the action of the zinc surround, which

becomes positive ionizing, and thus, functions in a self-

sacrificial manner acts as an anticorrosive in order to

protect the iron/steel material by the effect of electro-

chemical action.

Such zinc’s sacrificial action as an anticorrosive for iron/steel

is a specific character which zinc possesses.

Calculation made above is based on the result gained intermediately

conducted by Japan’s Hot-Dip zinc Galvanizaing Association.
