Hot dipped cold rolled galvanized sheet metal is a kind of metal material made by immersing steel sheet into molten zinc liquid for galvanizing treatment, and then processed by cold rolling process. This material not only has the strength and toughness of steel, but is also covered with a uniform zinc layer, which greatly improves its corrosion resistance. The product includes the following features.
Excellent corrosion resistance: the galvanized layer can effectively prevent the surface of the steel plate from being eroded by air, moisture and other corrosive mediums, and prolong its service life. Good processability: galvanized sheet has good cold working performance, which can be adapted to various forming and processing needs. Beautiful appearance: the surface of galvanized layer is smooth and bright, with high decorative properties. The presence of the galvanized layer gives the hot dipped cold rolled galvanized sheet metal excellent corrosion resistance. Zinc is a chemically more active metal that reacts easily with oxygen to generate a dense oxide protective film, thus preventing the internal steel sheet from corrosion. In addition, the zinc layer can also react chemically with other corrosive media in the environment to further protect the steel sheet
