Galvanizing refers to the surface treatment technology that coats a layer of zinc on the surface of metal , alloy or other materials to play the role of beauty and rust prevention . The main method used is hot-dip galvanizing.

Zinc is soluble in acid and alkali, so it is calledamphoteric metal . Zinc hardly changes in dry air. In humid air, a dense basic zinc carbonate film is formed on the zinc surface. In the atmosphere containing sulfur dioxide, hydrogen sulfide and marine, the corrosion resistance of zinc is poor, especially in the atmosphere containing organic acid at high temperature and high humidity, the zinc coating is easily corroded. The standard electrode potential of zinc is -0.76V. For the steel substrate , the zinc coating is an anodic coating, which is mainly used to prevent the corrosion of steel, and its protective performance has a great relationship with the thickness of the coating. The protective and decorative properties of zinc coating can be significantly improved after passivation treatment , dyeing or coating with light protectant.
