What material is used for coating a metal during the galvanization process?

During the galvanization process, zinc is the material commonly used to coat metal. This is primarily done to protect the underlying metal from corrosion. Zinc has excellent corrosion-resistant properties, which make it an ideal choice for coating materials like steel or iron that are susceptible to rusting when exposed to moisture and air. The protective layer of zinc acts as a barrier and also provides sacrificial protection – even if the coating is scratched, the exposed steel can still be protected because zinc will corrode preferentially to the underlying metal. This unique property of zinc ensures the longevity and durability of metals used in various applications, especially in outdoor environments where exposure to the elements can lead to deterioration.
