Surface treatment of the packaging steel strip

With the development of cold bending steel expanding its USES, especially for its corrosion resistance performance of the demand is higher and higher, in order to prolong the life of the product, manufactured packaging steel strip surface treatment of cold bending steel. Surface treatment of steel plate mainly package. Enclosed metal coating packaging steel strip, organic coating packaging steel strip, organic thin film laminated packaging steel strip, surface polishing packaging steel strip, etc. Is commonly used in cold bending steel production of metal coating packing strip is galvanized steel strip. Plating catalpa packing belt is divided into hot dip galvanized steel strip and electricity galvanized steel with two kinds of packing. Electric galvanized steel belt wrapped cold bending formability and surface quality of the galvanized steel is good, but molding section shape complex packaging steel strip. At present abroad also USES alloying galvanized sheet, aluminum zinc alloy steel plate and single galvanized sheet to produce cold bending steel, its abrasion performance high specific heat of galvanized sheet. In addition, in addition to the packaging of galvanized steel belt, and also USES the aluminum plating, copper plating, qin plating, chrome plating, nickel plated steel to produce specific purposes such as cold bend section steel.
