Hot dip galvanized steels are continuously coated on both sides with a zinc coating. The hot dip process provides a tight metallurgical bond between the steel and the coating. A thin alloy layer readily permits normal fabrication practices without incurring significant coating damage. This process results in a material with the strength and formability of steel plus the corrosion protection of zinc. Zinc protects the base metal by providing a barrier to corrosive elements and also by the sacrificial nature of the coating. It is widely used in the automotive and construction industries.
