Galvanizing is the practice of immersing clean, oxide-free iron or steel into molten Zinc in order to form a Zinc coating that is metallurgically bonded to the iron or steel's surface. The Zinc coating protects the surface against corrosion by providing protection to the iron or steel in two ways. It shields the base metal from the atmosphere because it is more electronegative than iron or steel; the Zinc gives cathodic or sacrificial protection. 

Even if the surface becomes scratched and the base metal is exposed, the Zinc is slowly consumed while the iron or steel remains protected from corrosion. The hot dip galvanizing process is adaptable to coating nearly all types of fabricated and non-fabricated products such as wire, tanks, sheets, strips, pipes and tubes, fittings, hardware, wire cloth, hollow-ware, and structural assemblies.
