The continuous hot dip or zinc coated sheet comes in eight classes based on the thickness of the zinc coating.Welding of zinc-coated steel can be done,but specific precautions should be taken.When galvanized steel is arc welded the heat of the welding arc vaporizes the zinc coating in the weld area.ZINC COATINGS - American Galvanizers AssociationElectrogalvanized (electroplated) coatings are created by applying zinc to steel sheet and strip by electro-deposition.Similar to sheet galvanizing,the operation is continuous and coating thickness is minimal.Applied in a steel mill,sheet or strip is fed through entry equipment into a series of washes and rinses then into the zinc plating bath.ZINCGRIP GI Steel Hot Dip Galvanized SteelZINCGRIP &Steel is continuously coated on both sides with a zinc coating,using a hot dip process that we originally pioneered.With its tight metallurgical bond between the steel and the coating,ZINCGRIP Steel provides 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 preferentially corroding in place of the base steel.
