Characteristics Of Galvanized Channel Steel

(1) A thick and dense pure zinc layer covers the surface of steel, which can avoid contact between the steel substrate and any corrosive solution, protecting the steel substrate from corrosion. In the general atmosphere, a thin and dense layer of zinc oxide is formed on the surface of the zinc layer, which is difficult to dissolve in water and therefore plays a certain protective role on the steel substrate. If zinc oxide forms insoluble zinc salts with other components in the atmosphere, its anti-corrosion effect is more ideal.
(2) It has an iron zinc alloy layer, which is dense and exhibits unique corrosion resistance in marine salt spray atmospheres and industrial atmospheres;
(3) Due to its strong bonding and zinc iron mutual solubility, it has strong wear resistance;
(4) Due to the good ductility of zinc, its alloy layer adheres firmly to the steel base, so hot-dip galvanized parts can be formed through various processes such as cold stamping, rolling, wire drawing, bending, etc. without damaging the coating;
(5) After hot-dip galvanizing of steel structural components, it is equivalent to one annealing treatment, which can effectively improve the mechanical properties of the steel substrate, eliminate the stress during the forming and welding of steel components, and is conducive to the turning processing of steel structural components.
(6) The surface of the hot-dip galvanized parts is bright and beautiful.
(7) Pure zinc layer is the most plastic galvanized layer in hot dip galvanizing, with properties similar to pure zinc and ductility, making it flexible.
