What is purpose of zinc coating on GI sheet?

Galvanizing, or galvanization, is a manufacturing process where a coating of zinc is applied to steel or iron to

offer protection and prevent rusting.

What is galvanized steel and why is it useful?
Galvanization is the process of applying a protective zinc coating to steel or iron in order to prevent premature

rust and corrosion. Proponents of galvanized steel, who may use it to construct or repair steel structures, for

example, benefit from lower maintenance and repair costs because of its special properties.
