what is steel grating ? -- Steel grating is made by bearing bar and cross bar according to the flat-steel weft arrangement, in high-pressure spacing on resistance welder welded by cutting, incision, opening, overlock process such as processing and into customer requirements finished products.
The steel gratings produced by our company feature high strength, light structure, large load-bearing capacity, and convenient loading. The hot-dip galvanizing coating endows the products with excellent corrosion resistance.
Due To Its Extremely High-Cost Performance, Hot-Dip Galvanized Steel Grating Is Widely Used In Construction Projects Of Paved Ditch Roads On New And Old Roadbeds. The Surface Of Hot-Dip Galvanized Steel Grating Has Undergone Special Hot-Dip Galvanizing Treatment. It's Chemical And Physical Properties Are Stable And It Is Not Susceptible To Corrosion And Oxidation By Air And Microorganisms. It Can Significantly Enhance The Trench Load Capacity.
