What is electroplating?

Galvanizing  is the process of adding a layer of zinc to the outer surface of a metal. The idea is to add a protective coating to the underlying metal, reducing the likelihood of corrosion or rust.

Galvanizing process varies with specific technology. However, the most important part of the process is that it usually involves enclosing steel or iron in zinc, which may be in a liquid or dust-like state. When zinc is introduced, the iron in the surrounding metal reacts with the zinc to form a tightly bonded alloy coating.
