Galvanizing

Galvanizing is process of depositing a layer of zinc coating on top of steel or iron to prevent rusting and improve the lifespan.
The thickness of zinc coating is measured in microns.

The two basic methods of achieving galvanizing are:
1. Electroplating
2. Hot-dip Galvanizing

Hot-dip galvanizing is preferred as it gives better quality of coating.
Ducts, pipes, fixtures, etc are some of the common items which are galvanized.
