Steel grating is made of flat steel and bars by welding with certain distances. Steel grating goes through cutting, opening, edging and other processes.The steel grating  enjoy the features of high strength, light structure, high bearing, convenience for loading and other properties. The hot dipped zinc coating gives the steel grating excellent anti-corrosion resistance.

Steel grating is widely used in the platform, corridor, bridge, well covers, stairs, fencing for petroleum, chemical, power plant, waste treatment plant, civil engineering projects and environmental projects.
