What is the main use of galvanized sheet?

Galvanized sheet is a steel plate coated with a layer of zinc on the surface. Galvanized steel plate is a widely used, economical and effective anticorrosion method. Galvanized sheet was used to be called "white iron sheet" in the early years. According to the production process can be divided into hot galvanized sheet and electrogalvanized sheet. The zinc layer thickness of hot galvanized sheet is thicker, which is used to make parts with strong corrosion resistance for open air use. The zinc layer thickness of electrogalvanized sheet is thin and uniform, and it is mostly used for painting or making indoor supplies.
