Stainless steel grating is a kind of steel grating, but compared with ordinary steel grating, there are some differences and differences: First of all, in terms of raw materials, stainless steel grating is stainless steel, while ordinary steel grating The grating is made of carbon steel or stainless steel; secondly, the surface of the stainless steel grating is not subjected to anti-corrosion treatments such as spray painting or hot-dip galvanizing, but is polished to remove the welding slag or slag produced during the welding process of the steel grating. Weld marks, etc. Polishing treatment can make the metal surface very shiny and bright. Generally, stainless steel products must be polished in order to be beautiful.
There are many ways to polish, including physical treatment and chemical treatment. After polishing, not only the impurities in the stainless steel matrix and the iron-rich layer on the surface can be removed, but also chromium and nickel can be concentrated on the surface to form a passivation film. This can improve the anti-rust performance of stainless steel by 2-3 times. The raw material selected for stainless steel grating is stainless steel, and stainless steel has different brands and compositions. If it is used on steel grating, then it has some commonly used trademarks, such as 304, 201, 316, 316L, 310 and 310S.
Stainless steel grating is made of stainless steel flat iron welded by welding wire. Because the welding wire will leave black solder spots on the stainless steel grating of the platform, and the appearance is not beautiful, so the stainless steel grating needs to be polished. The raw material of the stainless steel grating is stainless steel grating, and its production process is the same as that of ordinary gratings. Steel gratings are relatively similar. However, it does not need to use anti-corrosion treatment such as spray painting or hot-dip galvanizing, but needs surface polishing to remove welding slag or scars left during the welding process. It is to make the appearance of the steel grating bright and new, and make the overall appearance beautiful and generous.
When it comes to welding steel gratings, there are basic requirements, which are: the welding joints of steel gratings must be tight, without defects such as welds and burrs. In addition, the welding surface must be flat and smooth. After electrolytic polishing technology, the stainless steel grating is as bright as ever. It is not only beautiful in appearance, but also rust-free and has a long service life. After the stainless steel grating is produced, it is polished and completed. Polishing treatment can make the metal surface very shiny. Generally, stainless steel gratings must be polished for beauty. There are many ways to polish, including physical treatment and chemical treatment. After polishing, not only the impurities in the stainless steel matrix and the iron-rich layer on the surface can be removed, but also chromium and nickel can be concentrated on the surface to form a passivation film. This can improve the anti-rust performance of stainless steel by 2-3 times.
