Channel steel channel steel channel steel (1) The surface of the steel covers a thick and dense pure zinc layer, which can prevent the steel substrate from touching any corrosive solution and protect the steel substrate from corrosion. In the general atmosphere, the surface of the zinc layer constitutes a very thin and dense zinc oxide layer, which is difficult to dissolve in water and maintains the steel substrate. If zinc oxide and other components in the atmosphere form an insoluble zinc salt, the anti-corrosion effect is more ideal.

　　(2) With iron-zinc alloy layer, combined with density, it has special corrosion resistance in marine salt spray atmosphere and industrial atmosphere;

　　(3) Because of the strong bonding, zinc and iron are mutually soluble and have strong wear resistance;

       (4) Because zinc has excellent ductility, its alloy layer is firmly attached to the steel substrate, and can be formed by cold stamping, rolling, stretching, bending and other methods to form hot-dipped parts without damaging the coating;

　　(5) Hot The galvanized steel structure is equivalent to annealing treatment, which can effectively improve the mechanical function of the steel matrix, eliminate the stress of forming and welding steel parts, and is beneficial to the turning of the steel structure.

　　(6) The hot-dip galvanized parts have a beautiful appearance.

　　(7) The pure zinc layer is the most plastic layer in hot-dip galvanizing, and its function is basically close to pure zinc, and it is ductile and therefore elastic.
