Heavy Duty Steel Grating Storm Ditch Trench Drain Drainage Cover Steel Grates
Steel grating is a type of steel product made by crossing flat steel and horizontal bars (twisted square steel, square steel, round steel, flat steel, etc.) at a certain distance, and welding them into a square grid in the middle. Steel grating is mainly used to make gutter cover plates, steel structure platform plates, steel ladder step plates, etc. Horizontal bars are generally made of twisted square steel. Steel grating is generally made of carbon steel and has a hot-dip galvanized surface to prevent oxidation. Stainless steel can also be used for production. Steel grating has ventilation, lighting, heat dissipation, anti slip, explosion-proof and other properties.
