Stainless steel material quality selection and processing and production methods for stainless steel gratings: High-quality stainless steel gratings generally use 304, 316, 316L, etc. There are two processing and production methods: machine pressure welding and manual production, which are machine pressure welding and high-voltage resistance pressure welding. The machine and manipulator automatically place the crossbar horizontally on the evenly arranged flat steel, and press-weld the crossbar into the flat steel through powerful electric welding power and hydraulic pressure, so as to obtain strong solder joints, extremely high stability and strength. High-quality stainless steel grating, hand-made stainless steel grating is punched in the flat steel first, and then the cross bars are put into the holes and spot welded. There will be gaps between the cross bars and the flat steel, but every contact point can be Welding achieves the same molten connection between flat steel and twist steel, so the welding will be stronger and the strength will be improved, but the appearance is not as beautiful as pressure welding!
The advantages of stainless steel grating products are quite obvious: light weight, high strength, large load-bearing capacity, economical material saving, ventilation and light transmission, modern style, beautiful appearance, anti-skid and safe, easy to clean, simple installation, and durable. Treaded steel grating is generally made of carbon steel, and the surface is hot-dip galvanized to prevent oxidation. It can also be made of stainless steel. Steel grating has ventilation, lighting, heat dissipation, anti-skid, explosion-proof and other properties. The stainless steel gratings produced and sold by steel grating manufacturers are widely used in various factories and engineering projects at home and abroad.
Stainless steel grating classification: flat type, toothed type and I type, with more than 200 specifications and varieties (according to different use environments, different protective treatments can be carried out on the surface. The gap width of the stainless steel grating plate can be adjusted according to the purpose of removing dirt. Depending on the method and the requirements of the water pump, the manual cleaning grille gap is generally 16-25mm. The grille in front of the grit chamber or sedimentation tank is generally 15-30mm, and the maximum is 40mm. There are three commonly used mechanical slag cleaning equipment, namely. Chain type, mobile and wire rope traction grate cleaning machines. The stepping steel grating is generally made of carbon steel, and the surface is hot-dip galvanized, which can prevent oxidation. The steel grating can also be made of ventilation. Lighting, heat dissipation, anti-skid, explosion-proof and other properties.
