Hot-dip galvanizing, also known as hot-dip zinc coating, involves melting zinc ingots at high temperatures, adding some auxiliary materials, and then immersing metal components into a galvanizing bath to coat them with a layer of zinc. The advantages of hot-dip galvanizing include its strong corrosion resistance and good adhesion and hardness of the zinc coating. The drawbacks are its higher cost, the need for extensive equipment and space, and the difficulty of fitting large steel structures into the galvanizing bath. Additionally, thin steel structures are prone to deformation during hot-dipping. Rich zinc coatings typically refer to corrosion-resistant coatings containing zinc powder. The zinc content in rich zinc coatings on the market can range from 1%.
