Aluminum steel bar grating
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.
1, Plain type:
One of the most wiely used gratings, available for flooring, sidewalk, dranage pit cover, stair tread, etc.
2, Serrated type:
Better Non-skid property & safety compared with plain grating
Finishes: electro galvanized, hot dipped galvanized, according to the difference surface treatment.
