Galvanized channel steel

peculiarity

(1) A thick dense pure zinc layer is covered on the surface of the steel, which can avoid the contact of the steel matrix with any corrosion solution and protect the steel matrix from corrosion. In the general atmosphere, the surface of the zinc layer forms a thin and dense zinc oxide layer surface, which is difficult to dissolve in water, so it plays a certain protective role on the steel matrix. If zinc oxide and other components in the atmosphere to form insoluble zinc salt, the corrosion protection is more ideal.

(2) It has an iron-zinc alloy layer, which is compact and has unique corrosion resistance in Marine salt spray atmosphere and industrial atmosphere;

(3) Due to the firm combination, zinc-iron miscible, with strong wear resistance;

(4) Due to the good ductility of zinc, its alloy layer is firmly attached to the steel base, so the hot-plated parts can be cold-blanking, rolling, drawing, bending and other forms without damaging the coating;

(5) After hot-dip galvanized steel structural parts, it is equivalent to a annealing treatment, which can effectively improve the mechanical properties of the steel matrix, eliminate the stress during the forming and welding of the steel parts, and is conducive to the turning of the steel structural parts.

(6) The surface of the hot-dip galvanized part is bright and beautiful.

(7) Pure zinc layer is the most plastic galvanized layer in hot dip galvanizing, its properties are basically close to pure zinc, ductility, so it is flexible.

Scope of application

The application of hot-dip galvanized channel steel is also expanded with the development of industry and agriculture. Therefore, hot-dip galvanized products in buildings (such as: glass curtain wall, power tower, communication grid, water and gas transmission, wire bushing, scaffolding, houses, etc.), Bridges, transportation; Industry (such as chemical equipment, petroleum processing, ocean exploration, metal structures, power transmission, shipbuilding, etc.); Agriculture (such as sprinkler irrigation, heating houses), etc., has been widely used in recent years. Because hot-dip galvanized products have beautiful appearance, good corrosion resistance and other characteristics, its application is more and more extensive.
