Steel Grating
Steel grating is made of flat steel and cross bar. It is mainly used to make the ditch cover plate, steel structure platform plate, steel ladder step plate, etc. The cross bar is usually made of twisted square steel. Steel grating is generally made of carbon steel which is usually hot dipped-galvanized to prevent oxidation. It can also be made of stainless steel. Steel grating plate has the properties of ventilation, lighting, heat dissipation, anti-skid, explosion-proof etc.
