Q345B channel steel

Features

(1) A thick, dense layer of pure zinc covers the steel surface, preventing contact between the steel substrate and any corrosive solutions, thereby protecting the steel from corrosion. In normal atmospheric conditions, a thin, dense layer of zinc oxide forms on the zinc surface, which is hardly soluble in water, thus providing some level of protection to the steel substrate. The protective effect is further enhanced if zinc salts that are insoluble in water are formed by the zinc oxide interacting with other atmospheric components.

(2) Features a ferrum-zinc alloy layer, with a dense bond, exhibiting unique corrosion resistance in marine salt fog atmosphere and industrial atmospheres.

(3) Due to its strong bonding, zinc-iron alloy has excellent wear resistance.

(4) Due to zinc's excellent ductility, its alloy layer adheres firmly to the steel substrate, allowing hot-dip parts to be formed into various shapes such as cold stamping, rolling, wire drawing, and bending without damaging the coating.

(5) After hot-dip galvanizing steel structural components, it is equivalent to a single annealing process, which effectively improves the mechanical properties of the steel matrix, eliminates stresses during the forming and welding of steel parts, and is conducive to the turning processing of steel structural components.

(6) The surface of the hot-dipped galvanized parts is bright and aesthetically pleasing.

(7) The pure zinc layer is a malleable zinc coating in hot-dip galvanizing, with properties closely resembling pure zinc, exhibiting ductility, thus it is highly flexible.
