Stainless steel grating is also called stainless steel grating, stainless steel grating, etc. Stainless steel grating is a steel grating made of stainless steel. Its production process is similar to that of ordinary steel grating, except that it does not need to be spray painted or Anti-corrosion treatment such as hot-dip galvanizing requires surface polishing to remove welding slag or scars left during the welding process. The selection of stainless steel grating is the same as that of carbon steel grating. Its surface treatment includes acid whitening, passivation, polishing, etc. Stainless steel materials generally use 304, 316, 316L, 301, etc.
Stainless steel grating material: 1. 304: average corrosion resistance, the most commonly used and recommended. 2. 316 (316L): Strong corrosion resistance, more expensive. 3. 301: Weak corrosion resistance and cheaper.
Classification of stainless steel gratings: Stainless steel gratings can be divided into flat steel gratings, toothed steel gratings, and I-shaped steel gratings according to different flat steels. There are more than 200 specifications and varieties (according to different use environments, they can be Different protective treatments are applied to the surface).
Stainless steel grating production methods: including machine pressure welding and manual production:
1. Machine pressure welding uses a high-voltage resistance pressure welding machine. The robot automatically places the crossbar horizontally on the evenly arranged flat steel. The crossbar is pressure-welded into the flat steel through powerful welding power and hydraulic pressure, so that the welding spots can be obtained. High-quality steel grating with high stability, stability and strength.
2. The hand-made steel grating is to punch holes in the flat steel first, and then put the cross bars into the holes and spot weld them. There will be gaps between the cross bars and the flat steel, but every contact point can be welded to achieve the flat steel It is the same melted connection as twist steel, so the welding will be stronger and the strength will be improved, but the appearance is not as beautiful as pressure welding.
Features of stainless steel grating:
1. Light weight, high strength, large carrying capacity, material saving and economy, ventilation and light transmission, modern style and beautiful appearance.
2. Anti-slip and safe, easy to install, easy to clean, and durable.
3. Strong anti-corrosion ability, anti-oxidation, wide range of uses and long service life.
Usage occasions of stainless steel grating:
1. The use environment is harsh and requires acid and alkali corrosion resistance (such as chemical plants, environmental protection equipment, sewage treatment plants, ethylene plants, etc.).
2. Occasions with high hygiene requirements (pharmaceuticals, food processing, high-end hotels).
3. Occasions with high requirements on appearance (such as shopping malls, landscapes, theaters). In addition, stainless steel gratings are widely used in shipbuilding, petrochemicals, food processing plants, power plants, sewage treatment plants, chemical plants, refineries, steel plants, machinery manufacturing plants, cement plants, bridge projects, municipal engineering projects and other fields. Especially used in some environments with high anti-corrosion requirements, it is usually used as stainless steel gutter covers, stainless steel stair treads, stainless steel grating ceilings, stainless steel rainwater grates, etc.
Surface treatment of stainless steel grating:
1. Pickling, the surface is matte off-white. (Pickling: After pickling in a pickling tank and using passivation solution and deionized water, the passivation film lost due to processing will be restored.)
2. Electrochemical polishing, the surface is brighter and the finish is higher. (Electrochemical polishing: performed in an electrolytic horizontal tank to produce a polished surface with uniform color and remove dirt.)
3. The finished product is heated and polished, then electrochemically polished, and finally chrome plated to achieve a mirror effect.
