Manufacturing technology of electric galvanized coil

Electrogalvanizing coil is mainly composed of steel coil and galvanizing process. First, the cold rolled steel coil is chemically treated to remove surface rust, oil and impurities, and improve surface roughness. The surface is then coated with a zincizing agent to promote the formation of the zinc layer. Next, the steel coil is immersed in an electrolyte containing metal zinc ions, and through the action of an electric current, a uniform layer of zinc is formed on the surface of the steel coil. Finally, through temperature rise, cooling, oiling and other processes, the electrogalvanized coil is made. Through the application of these manufacturing processes, the electrogalvanized coil has high quality, good corrosion resistance and beautiful appearance.

Second, the application of electric galvanized coil

1. Construction industry

As a traditional industry, the application of electric galvanized coil in the construction industry is more extensive. It is usually used to make building doors and Windows, roofs, walls and so on. Have a wide range of market demand.

2. Transportation industry

With the improvement of people's living standards, the rapid development of the transportation industry, the application of electric galvanized coil more and more. Its most common application is to make car body panels, so that it has a good appearance and corrosion resistance.
