Regular spangle galvanized steel sheet is a type of galvanized steel sheet that has a traditional, uniform spangle pattern on its surface. The spangle pattern is created during the hot-dip galvanizing process, which involves coating the steel sheet with a layer of zinc to provide corrosion resistance.
The regular spangle pattern is characterized by small, crystalline zinc grains that form on the surface of the steel sheet during the galvanizing process. The pattern is uniform and evenly distributed across the surface of the sheet, giving it a traditional and aesthetically pleasing appearance.
