Galvanized strip steel is a kind of raw material called (zinc, aluminum) for cold rolling or hot rolling long and narrow strip steel plate. Hot dip galvanizing has the advantages of even coating, strong adhesion and long service life. Complex physical and chemical reactions occur between the substrate of hot-dip galvanized strip steel and the molten bath, forming 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, it has strong corrosion resistance.
The application effect of galvanized strip steel meets the modern demand and has been widely used as building materials. Galvanized strip steel has the characteristics of rust resistance and corrosion resistance for many years. It can keep its own performance and appearance without being affected by external adverse environment. In the process of using galvanized strip steel, in order to improve its operating efficiency and its own characteristics, the finished galvanized strip steel can be post-treated to make its performance better
