Hot Dipped Galvanized Steel

Hot dipped galvanized steel is the most common method of galvanizing, and produced by dipping the steel into a molten bath of zinc.  While in the bath, the iron in the steel reacts with the zinc to form a series of zinc-iron alloy layers, with an outer layer of pure zinc that will prevent the surrounded alloy from corrosion.  The coating will act as a self-sacrificing later, further protecting the base steel from corrosion.  The coating is harder than the base steel, which also provides superior abrasion-resistance.  Common uses of hot dipped galvanized steel are HVAC components, roofing, exterior construction components, automotive components, garage doors, and fasteners.
