Galvanized sheet is a metal material made of iron alloy, first of all, it has a high corrosion resistance, can be used in harsh environments for a long time without damage. Secondly, galvanized sheet has good wear resistance and scratch resistance, and is not easy to be damaged by mechanical damage. In addition, galvanized sheet also has good thermal and electrical conductivity, and can be used to make electrical equipment and heat exchangers and other products. The production process of galvanized sheet is to immerse the iron plate in the molten zinc, so that the zinc and iron react to form a protective layer of zinc-iron alloy, so as to achieve the protection of the iron plate. It is a kind of metal material commonly used in construction, automobiles, electrical appliances and other fields, and has a wide range of application prospects.
