Products Description
Steel grating is a type of construction material composed of steel bars. It typically consists of parallel load – bearing bars (usually flat bars) and cross – bars (such as round bars or twisted square bars) that are joined together, usually by welding or mechanical fastening methods.
ASTM A36 or 235JR Hot dip galvanized metal floor gratings are typically made from high – quality carbon steel or stainless steel.
Carbon steel offers good strength and toughness at a relatively low cost, while stainless steel provides enhanced corrosion resistance and oxidation resistance, making it suitable for environments with high corrosion requirements.
During the manufacturing process, a series of international and domestic standards need to be followed, such as ASTM A123/A123M, AS 1650, BS 729, GB 2518, etc., to ensure the quality and performance of the product.

Application Of Galvanized Steel Grating
1.Walkways
Offers a secure walking surface for industrial plant, factory, and warehouse personnel.
The open grid design is slip-resistant and allows dirt, liquids, or debris to fall through.
2.Steel Staircases
Perfect for industrial and commercial stair treads where strength and slip resistance are paramount.
Serrated or Anti-slip inserts are available for additional safety.
3.Work Platforms
It is worldwide known that at workshops or in the maintenance areas the machines, the facilities or the people can be supported.
Enables ventilation and provides easy cleaning of work bench.
4.Drainage Areas
Open grating design permits free passage of water, oils and other fluids.
Typically has been applied to open air places, factory ground and by the sides of drainages.
