Building Material Steel Floor Grating For Driveway Metal Grate
JH Steel gratings consist of a series of bearing bars cross jointed by welding at various intervals with cross bars (twisted square bars, square bars, round bars, flat bars etc., to form a kind of steel products with square lattices among them. Their main applications are drain covers, steelwork platform panels, and steel stair treads.

Steel Grating is made of flat steel and bars by welding with certain distances. It goes through cutting, opening, edging and other processes. The products enjoy the features of high strength, light structure, high bearing, convenience for loading and other properties. The hot dipped zinc coating gives the product 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.
Bearing bar pitch at 60mm
is especially for mining industrial production, the bearing bar pitch is 60mm, it solved the mineral splash in a hallway behind accumulation problems, often used in mineral mining and processing project . for more save material, is the best choice of condole top
Bearing bar pitch at 30mm
For the checker plate grating of the most commonly used models, the bearing bar pitch is 30mm. conform to the united states ,Australia , japan, and other countries. For this series of checker plate grating are the most dense and have the highest strength ,suitable for all kinds of application.
Bearing pitch at 40mm
For the checker plate grating of the most economic and light model, the bearing pitch is 40mm. accord with Britain, germany, france and japan standards specified fixed platform, aisle and stair step specification . often used in belt corridor ,warehouse shelves , the attic panel , shallow bridge ,guard railing ,sun shading etc.
