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:

Fastening Methods
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-
ate supports.
Non Standard Requirement
S.H Gratings are manufactured in numerous combinations of bearing bar height and thickness, bearing bar pitch and cross bar pitch.
Our complete range of gratings should cover the requirement for any projects. However, for any other combinations, please contact

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.
