Description of Steel Grating
Steel Grating is made of flat steel in accordance with a certain distance and cross arrangement, the use of gas welding, welding into the middle with a square lattice of steel products.Steel grating is regarded as industrial grade bar grating, which is extremely strong, durable and corrosive resistant for all load bearing applications and is primarily used for pedestrian and light vehicle traffic. Flat steel is generally cold rolled Q235 flat steel, can also be hot rolled I flat steel, tooth flat steel, inclined flat steel, stainless steel flat steel and other specs.
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.
Materials: mild steel or stainless steel.
Surface treatment: untreated, painting or hot dip galvanizing.
Steel grating with America standard can also be fabricated.
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
- Light weight
- great load-bearing capacity
- non-slip and safe
- easy installation
- material-economic
- sturdy and durable
- ventilated, easy to clean and attractive appearance.
