Galvanized steel strips is cold-rolled or hot-rolled , long and narrow strips of steel in varying degrees of coated with a layer called (zinc, aluminum) raw materials. Hot -dip galvanizing has the advantages of uniform coating,strong adhesion and long service life.
The complex physical and chemical reaction takes place between hot-dip galvanizing strip steel substrate and molten bath to form a corrosion-resistant zinc-iron alloy layer with compact structure. The alloy layer is integrated with the pure zinc layer and the strip steel matrix.Therefore,its corrosion resistance is strong.

Galvanized Steel Strip is generally used to make steel pipe, such as: Greenhouse Pipe, drinking water pipe, heating pipe, gas transmission pipe; also can be used in construction, light industry, automobile, agriculture, animal husbandry and fisheries and commercial industries.
Among them, the construction industry is mainly used to manufacture anti-corrosion industrial and civil building roof panels, roof Grilles, etc. . The light industry uses them to manufacture housings of household appliances, civil chimneys, kitchen appliances, etc. , automobile industry is mainly used for manufacturing corrosion-resistant parts of Cars, agriculture, animal husbandry and fishery are mainly used for grain storage and transportation, meat and aquatic products, etc; Steel Structure Sandalwood (C, Z steel) ; Light Steel Keel, suspended ceiling Keel, etc. .
