[0002] Hot-dip galvanizing is a surface treatment technology for anti-corrosion of steel components. It forms a protective layer by immersing the steel material in molten zinc liquid. Hot-dip galvanizing, also known as hot-dip galvanizing, is a process that uses the reaction between the iron matrix and molten zinc to form an iron-zinc alloy layer on the surface of the steel. This alloy layer can provide good adhesion, so that the pure zinc layer is closely combined with the iron matrix. Compared with other metal protection methods, the advantage of hot-dip galvanizing is that it combines physical barriers with electrochemical protection, and has excellent coating bonding strength, density, durability and maintenance-free. At the same time, it also performs well in terms of economy and adaptability to product shape and size.
