1.After hot-dip galvanizing of steel structural components, it is equivalent to a single annealing treatment, which has a significant effect on improving the mechanical properties of the steel substrate and eliminating the stress during forming and welding of steel components. This is very beneficial for turning the steel structure. The square pipes after hot-dip galvanizing have a bright and beautiful surface, and the pure zinc layer is the most plastic galvanized layer in hot-dip galvanizing, with properties almost equivalent to pure zinc and ductility, It is also flexible;

2. Because zinc has good ductility and its alloy layer is firmly attached to the steel substrate, hot-dip galvanized parts can be formed through various processes such as cold stamping, rolling, and wire drawing without damaging the coating. Due to the strong bonding between zinc and iron, hot-dip galvanized steel pipes have excellent wear resistance. If a thick and dense pure zinc layer is covered on the surface of steel, it can avoid contact between the steel substrate and any corrosive solution, To protect the steel substrate from corrosion, an oxidation protective layer is formed on the surface of the zinc layer in general atmosphere.
