Steel grating is also called steel grid plate. Grating is a kind of steel product made by cross-arranging flat steel at a certain spacing with cross bars and welding them into a structure with square grids in the middle. It is mainly used as ditch cover plates, steel structure platform plates, tread plates for steel ladders, etc. The cross bars generally use twisted square steel. Steel grating is generally made of carbon steel, with hot-dip galvanizing on the surface, which can prevent oxidation. It can also be made of stainless steel. Steel grating has properties such as ventilation, lighting, heat dissipation, anti-slip, and explosion-proof. It is widely used in platforms, walkways, trestles, ditch covers, well covers, ladders, fences, factory construction and other fields in petroleum chemical industry, electric power, tap water, sewage treatment, port terminals, building decoration, shipbuilding, self-propelled parking lots, municipal engineering, environmental sanitation engineering, etc.
