Steel grating, also known as grid plate, is manufactured by welding flat steel with cross or round bars at specific intervals. Our steel grating features high strength, lightweight structure, excellent load-bearing capacity, and convenient installation. The hot-dipped zinc coating provides superior corrosion resistance.
Hot-dip galvanized steel grating offers multiple advantages: material efficiency, cost-effectiveness, easy installation, durability, lightweight construction, no dirt accumulation, and excellent ventilation, lighting, heat dissipation, and resistance to corrosive environments including acid and alkali conditions.
