Steel Bar Gratings are suitable for building materials applied for power stations, boiler, ship building, petrochemical, chemical and general industrial factory buildings and municipal construction. Also known as Welded Steel Bar Grating or Pressure Weld Steel Grating.
Platform Steel Grating Channels - Big Span Steel Grate Structure Panels
Platform Channel Gratings are made of aluminum or steel alloy bar structure panels with big bar spacing and strong ability of anti-side shocking. Can be supplied with checkered plate shielding, installation connectors and other accessories.
Platform Steel Bar Grating are new building materials used in construction of power plants, boilers, ship buildings for platform decking structure. The steel bar grating platform structures enjoy good air and light ventilation, non-slip property, good bearing capacity, easy cleaning and installation.
Steel grating is made by welding with flat steel and bars 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.
Plain Flat Welded Bar Type Steel Grating
Steel Bar 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.
