Steel grating, also known as grille, steel bar grating or grid plate, is made of flat steel and twisted steel. The steel grating is durable and more affordable than other products. Its main purpose is in power plant platform and parking platform, maintenance platform, ditch cover and tread board. Steel grating is also used in environmental protection equipment and sewage treatment, etc., because of his superiority is increasingly widely used.
The production process of steel bar grating is generally divided into two types: machine pressure welding and hand-made. The machine pressure welding uses a high-voltage electric resistance welding machine. The robot automatically traverses the cross bar on the evenly arranged flat steel, and the cross bar is pressure-welded into the flat steel through strong electric welding power and hydraulic pressure, so that the welding spot can be obtained. High-quality steel bar 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 possible that each contact point is welded, so the welding is not strong and the strength is reduced.
Steel gratings specifications have a wide range of applications in construction, design and decoration, sewage treatment, engineering applications and other fields.
