Channel steel, now many occasions will be used, but many people do not understand the characteristics of it, then what is the characteristics of galvanized channel steel? How to determine the quality of the galvanized channel steel? The following is a detailed introduction to you.
1, the thicker, pure zinc coating is covered on the surface of steel, it can prevent the touch of steel matrix from any corrosive solution, and protect the steel matrix from corrosion. In the usual air, the surface of the zinc layer forms a thin and dense layer of Zinc Oxide layer. It is difficult to dissolve in water, so it has a certain maintenance effect on the steel matrix. If Zinc Oxide and other ingredients in the air produce insoluble zinc salt, the anticorrosion effect is more ambitious.
2, with iron - zinc alloy layer, contact fine, in the sea of salt fog air and industrial air to reflect the unique corrosion resistance;
3, because the connection is strong, zinc - iron is intersoluble, and has strong wear resistance.
4, zinc has excellent ductility. Its alloy layer is strongly adhered to the steel substrate, so hot plating can be molded by cold stamping, rolling, drawing and winding, without damaging the coating.
5, after hot galvanizing of steel structure, proper annealing treatment can effectively improve the mechanical properties of the steel matrix, eliminate the stress during welding and welding of steel structures, and facilitate the turning of steel structures.
6. The parts after hot dip galvanizing are bright and beautiful.
7, the pure zinc layer is the most plastic layer of galvanized zinc layer in hot dip galvanizing, its properties are basically close to pure zinc, with ductility, so it is flexible.
