galvanization.  Galvanization is the process of applying a
protective zinc coating to steel or iron, in order to prevent
rusting. The term is derived from the name of Italian scientist
Luigi Galvani. Although galvanization can be done with
electrochemical and electrodeposition processes, the most common
method in current use is hot-dip galvanization, in which steel
parts are submerged in a bath of molten zinc. In industry, the
term GI stands for galvanized iron, referring to a common
galvanized steel used in many applications such as air ducts and
trash cans.   Metal protection[edit]  In current use, the term
refers to the coating of steel or iron with zinc. This is done
to prevent rusting of the ferrous item. The value of galvanizing
stems from the corrosion resistance of zinc, which, under most
service conditions, is considerably greater
