Galvanized steel is defined as a carbon steel sheet coated with zinc on both sides. Hot-dip galvanized coatings are used on a multitude of materials ranging in size from small parts such as nuts, bolts, and nails to very large structural shapes. The process of galvanizing bonds a layer of zinc to the steel. Two of the most popular forms of carbon steel for manufacturing—galvanized and galvannealed—start with the same process, but that’s where the similarities end. Hot dip galvanized. Th e size of available zinc baths and material handling restricts the size of steel that can be galvanized. A G90 coating mass will exhibit about 50% longer life than a G60 coating mass.
