Zinc Coated Galvanized/Galvalume Steel Strap Coils Used For Steel -Frame Structure
Galvanized strip is a long, narrow strip of cold or hot rolled steel coated in varying degrees with a material called (zinc, aluminum). Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Complex physical and chemical reactions occur between hot-dip galvanized strip steel matrix and molten bath to form a tight zn-fe alloy layer with corrosion resistance. The alloy layer is integrated with the pure zinc layer and the strip matrix. Therefore, its corrosion resistance is strong.
Steel Strip belt is a large output, wide use, variety of steel. According to the processing method, it can be divided into hot rolled strip and cold rolled strip. According to their thickness, they can be divided into thin steel strip (thickness no more than 4mm) and thick steel strip (thickness greater than 4mm); According to the width, it is divided into wide steel belt (width is greater than 600mm) and narrow steel belt (width is less than 600mm); Narrow steel strip is divided into direct rolling narrow steel strip and narrow steel strip by longitudinal shear of wide steel strip; According to the surface state, it can be divided into original rolling surface and plating (coating) surface steel strip. According to the use, it can be divided into general and special (such as hull, bridge, oil drum, welded pipe, packaging, self-generated car, etc.) steel belt.
