Galvanization is a process used to protect metal, particularly steel, from rust and corrosion. This is typically achieved by coating the metal with a layer of zinc. The zinc acts as a barrier, preventing moisture and oxygen from reaching the underlying metal, which helps to extend its lifespan. There are different methods of galvanization, including hot-dip galvanization and electro-galvanization. In hot-dip galvanization, the metal is submerged in molten zinc, while electro-galvanization involves applying a zinc coating through an electrical process. Both methods are effective in enhancing the durability of metal products used in construction, automotive, and various industrial applications.
