The electrochemical potential of the hot-dip galvanized layer of the galvanized coil is more negative than that of the steel material, and the coating has excellent electrochemical protection performance. The coating layer is thick and dense, the coating layer and the steel substrate have strong bonding force, and the durability is good. The service life of the hot-dip galvanized steel with a galvanizing amount of 600g/m2 can reach more than 30 years. The hot-dip galvanized steel layer does not require maintenance during use. The hot-dip galvanizing process is simple and has strong adaptability to the shape and size of the steel. In addition to the strip steel, the hot-dip galvanizing process is also widely used in steel pipes, steel wires and structural parts, and has high productivity. Compared with other protective coatings economically, the galvanized layer has a strong competitiveness, especially for long-term used parts, the cost of the hot-dip galvanized layer is much lower than that of the paint coating.
