Description of Steel Grating
Steel grid is also known as steel grating plate, steel grating is
used in accordance with a certain distance and cross bar (twisted
square steel, square steel, round steel, flat steel, etc.) for
cross arrangement, and welded into a kind of steel products with
square lattice in the middle, steel grating is mainly used to make
gutter cover plate, steel structure platform plate, steel ladder
step plate and so on. The cross bar is generally made of twisted
square steel. Steel grid plate is generally made of carbon steel,
the appearance of hot dip galvanized, can play a role in preventing
oxidation. It can also be made of stainless steel. Steel grating
with ventilation, lighting, heat dissipation, anti-slip,
explosion-proof and other properties.
Materials: mild steel or stainless steel.
Surface treatment: untreated, painting or hot dip galvanizing.
Bearing bar specification:20*3 to 100*6
Bearing bar pitch:12.5,15,25,30,40,60mm etc. also be according to clients requirement
and 30,40,60mm are recommended
Cross bar picth:38,50,76,100mm,also be according to clients requiremen and 50,100mm
are recommended.
The Maximun length of black panel is 7350mm.
Steel grating standards:
A) China: YB/T4001.1-2007
B) USA: ANSI/NAAMM (MBG531-88)
C) UK: BS4592-1987
D) Australia: AS1657-1985
E) Japan: JJS.
Advantages of Steel Grating
Material saving: under the same load conditions, the most material
saving way, correspondingly, can reduce the material supporting the
structure.
Reduce investment: save materials, save labor, save time, free
cleaning and maintenance.
Simple construction: the pre-installed support is fixed with bolts
or welding, and one person can complete it.
Save time: the product does not need to be reprocessed on site, and
the installation is very fast.
Durable: hot dip zinc anticorrosion treatment before delivery,
strong impact and pressure resistance.
Modern style: beautiful appearance, standard design, ventilation
and light, giving people the overall smooth modern feeling.
Light structure: less materials, light structure, and easy to lift.
Anti-fouling: no rainwater, snow and dust.
Reduce wind resistance: because of good ventilation, small wind
resistance in strong winds, reduce wind damage.
Simple design: no small support beam, simple structure, simple
design; No need to design steel grid drawing, only indicate the
model can be, the factory can be designed for customers.
Ventilation, lighting, heat dissipation, explosion-proof, anti-slip
performance is good: acid and alkali corrosion ability: in the
range of PH 6 to PH 12.5, the zinc layer surface forms a stable
protective film, good corrosion resistance.
