Galvanized steel strip is a steel strip product that has been treated by hot dip galvanizing. In the production process, the steel strip is first prepared for surface treatment to remove impurities such as oil and oxides. Then, the steel strip is immersed in the molten zinc liquid, and a layer of zinc is uniformly covered on the surface of the steel strip by hot dip galvanizing process.
