The manufacturing process of electro-galvanized steel coil is a process of forming a uniform, dense and well-bonded zinc coating on the surface of the steel coil by electrolysis. Compared to other metals, zinc is a relatively inexpensive and easily plated metal that is widely used to protect steel, especially against atmospheric corrosion. In recent years, with the rapid development of the family car market, the basic popularization of household appliances and personal computers, the massive export of electronic products, and the development of the security door market, the demand for electro-galvanized sheets has grown too fast.
