Steel gratings are generally made of carbon steel, and the surface is hot-dip galvanized to prevent oxidation. It can also be made of stainless steel. The steel grating has ventilation, lighting, heat dissipation, anti-skid, explosion-proof and other properties.
Steel grating is an iron product with a square grid in the middle that is welded by a pressure welding machine or manually. Steel grating is mainly used to make ditch covers. Plate, steel structure platform plate, steel ladder step board, etc. Crossbars generally use twisted square steel
Steel grating is suitable for alloys, building materials, power stations, and boilers. shipbuilding. It is used in petrochemical, chemical and general industrial plants, municipal construction and other industries. It has the advantages of ventilation and light transmission, anti-slip, strong bearing capacity, beautiful and durable, easy to clean and simple to install. Steel grating has been widely used in various industries at home and abroad. It is mainly used as industrial platforms, ladder treads, handrails, passage floors, railway bridge sideways, high-altitude tower platforms, drainage ditch covers, manhole covers, road barriers, Three-dimensional parking lots, fences for institutions, schools, factories, enterprises, sports fields, garden villas, and can also be used as exterior windows of residential houses, balcony guardrails, highway, railway guardrails, etc.
