Coils for sale Galvanized strip steel is cold-rolled or hot-rolled, long and narrow strips of steel coated with a layer of raw materials called (zinc, aluminum) to varying degrees. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. The hot-dip galvanized strip steel substrate undergoes complex physical and chemical reactions with the molten bath to form a corrosion-resistant zinc-iron alloy layer with a tight structure. The alloy layer is integrated with the pure zinc layer and the strip steel substrate. Therefore, it has strong corrosion resistance. Advantages of galvanized steel coil The surface oxidation resistance is strong, which can enhance the corrosion resistance and penetration ability of the parts For example, the back of the air conditioning indoor machine, the back of the cabinet machine , the internal parts, the outer shell and the interior of the outdoor machine are made of galvanized sheet.These parts of the working environment will encounter rain, sun, hot gas corrosion and other strong oxidation conditions, so often use galvanized sheetCoils for sale website:http://www.baolaisteelpipes.com/coils/
