Steel grating is a type of steel product that is made of flat steel arranged in a cross pattern with a certain spacing and horizontal bars (twisted square steel, square steel, round steel, flat steel, etc.), and welded into a square grid in the middle. The horizontal bars are generally made of twisted square steel. Steel grating is generally made of carbon steel and hot-dip galvanized on the surface, which can prevent oxidation. Stainless steel can also be used for production. The steel grating has properties such as ventilation, lighting, heat dissipation, anti slip, and explosion-proof.
