Steel grating is available in varied form suitable for different application and overall load conditions. Hot dip galvanizing or painting can make them in excellent appearance, durability and enhanced economy. Galvanized steel grating is widely used in Power Station, Chemical Industry, Oil & Gas Industry, Boiler Plant, Mining and Refinery, etc.

Application:
Industrial platforms: These platforms, such as operating platforms in factory workshops andwarehouses, provide a non-slip, load-bearing walking surface.
Municipal facilities: These platforms are used for urban sewer and ditch covers, providing bothdrainage and safety functions.
Construction projects: These platforms serve as stair treads, decorative curtain wall gratings, orload-bearing panels in parking lots and overpasses.
Special applications: These platforms serve as corrosion-resistant platforms in the petroleum,chemical, and wastewater treatment industries, or as load-bearing gratings for heavy machinery.
