Hot Dipped Galvanized sheet and coil is made with a cold rolled substrate or base metal that is hot dipped with a zinc coating.  The zinc coating is added as a protective layer against rusting or oxidation.  Zinc is a noble metal and will sacrifice itself to the environment thus protecting the base cold rolled substrate from corrosion.  There is a linear correlation between the coating thickness and anticipated service life for any given zinc thickness.  The thicker the zinc coating on the surface of the metal the longer the anticipated service life will be.
