Hot-dip zincing and hot-dip galvanising are two different processes for corrosion protection of metals, with hot-dip zincing usually providing better corrosion resistance than hot-dip galvanising.
Hot-dip zincing is a process in which steel is immersed in a high-temperature zinc solution to cover the surface of the steel with a thicker layer of zinc, providing longer-term protection. Hot-dip galvanising, on the other hand, involves applying a thinner zinc alloy coating to the surface of the steel, with the main ingredients including zinc chloride, ammonium chloride and potassium chloride. The corrosion protection of hot-dip zinc is usually superior to that of hot-dip galvanising due to differences in the thickness of the zinc layer and the materials used. Moreover, hot-dip zinc is relatively more costly and the process is more complex, while hot-dip galvanising is relatively economical and suitable for areas where corrosion resistance is not particularly required.
In addition, hot-dip zinc and hot-dip galvanising have different areas of application, with hot-dip zinc being more suitable for corrosive environments such as external steel structures and large-scale projects, while hot-dip galvanising is more commonly used in areas such as household appliances, light industry and telecommunications.
