For many users, this kind of product can effectively resist the interference of the external environment. The Hot Dip Galvanized Steel Grating has a certain anti-rust ability, so it will play a more superior role in each similar product, highlighting it more. An important place to come.
In Hot Dip Galvanized Steel Grating Factory, grille is made by 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 crossbar on the evenly arranged flat steel, passing powerful welding power and hydraulic pressure. The crossbar is pressure welded into the flat steel, so that a high-quality steel grating with strong solder joints, high stability and high strength can be obtained. The hand-made steel grating is first punched on the flat steel, and then the horizontal rod is placed. Spot welding in the hole, there will be gaps between the cross bar and the flat steel, and it is impossible to weld at each contact point, so the welding is not strong and the strength is reduced.
