Explain the galvanizing process with regard to zinc and its importance to the uses of zinc.
What will be an ideal response?
Zinc's major use is in forming a protective coating over steel to prevent rust. This is referred to as galvanizing. Galvanizing involves placing the steel to be coated into a bath of molten zinc, which bonds to its surface. It is important that the coating be free of imperfections, such as pinholes, that permit moisture to reach the steel and cause it to rust. Both galvanized sheet and strip material are available.
