Steel Bar Grating is made of flat steel with a certain spacing and cross bar, and is welded into a steel product with a square lattice in the middle. It is mainly used for the ditch cover, the steel platform plate and the steel ladder. Treads, etc. The crossbar is generally made of twisted square steel.
Steel Bar Grating is generally made of carbon steel, and the surface is hot-dip galvanized to prevent oxidation. Can also be made of stainless steel. Steel grating has ventilation, lighting, heat dissipation, non-slip, explosion-proof and other properties.
The production standards for Steel Bar Grating are YB/T4001-1998 in China; in addition, the United States, the United Kingdom, Australia and New Zealand also have their own standards. The steel standard is in accordance with GB700-88 and GB1220-92.
The surface of the Steel Bar Grating can be punched to increase the slip resistance. Flat steel can also be made of flat steel of type I.
Steel Bar Grating is made by two methods: machine pressure welding and hand-made. The machine pressure welding uses a high-voltage resistance welding machine. The robot automatically traverses the crossbar on the evenly arranged flat steel, and presses the crossbar into the flat steel through strong welding power and hydraulic pressure, so that the solder joint can be obtained. High quality steel grating with high stability and strength. The hand-made steel grating is first punched on the flat steel, and then the crossbar is placed in the hole for spot welding. There is a gap between the crossbar and the flat steel, and it is impossible to weld at each contact point, so the welding is not firm. The intensity is reduced.
Steel bar grating use: petrochemical, municipal engineering, port engineering, machinery industry, power plant water plant, steel industry, manufacturing, food processing industry, sewage treatment plant, municipal engineering, sanitation engineering and other fields of platforms, walkways, trestles, Ditch covers, manhole covers, ladders, fences, guardrails and many other industries have been widely used.
