Ans. Galvanization is the process of coating a metal with a protective layer of zinc. It is a standard way of protecting iron from rusting. This can be accomplished by either dipping the metal to be protected in hot, molten zinc or electroplating it.
It has been shown for 150 years that coating iron and steel with molten zinc protects them from corrosion.
The zinc coating protects the part’s surface from the elements, preventing corrosion and weathering.
