Galvanized Grids/ Metal Grating/ Bar Grating/Steel Grating   Steel Grating Mesh 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 feature of high strength, light structure, high bearing, convenience for loading and other propertier. The hot dipped zinc coating gives the product excellent anti-corrosion    Material: high quality low carbon steel     Types: serrated,plain, and  I-shape type     Plain type:        One of the most wiely used gratings, available for flooring, sidewalk, drainages pit cover, stair tread, etc.       Serrated type:        Better Non-skid property & safety compared with plain grating        I-shape type         Lighter, more economical and practical comparing with plain grating            Finishes: electro galv, hot dipped galv, according to the difference surface treatment.   Application:   galvanized steel grating are widely used by various plants such as electric power,petroleum,chemical industry,metallurgy industry,machinery industry,shipbuilding, harbor,oceanographic engineering,building,paper mills,cement plant,medicine,spinning and weaving,foodstuff factory,transportation,municipal administration,parking lot,etc.
