Square pipe, short of square steel pipe and rectangular pipe, is of equal length and width. It is rolled from the strip steel through some process. Generally it is strip steel that is unpacked, leveled, curled, and weld into round pipe, which then rolled into square tube and cut into required length.

Cold rolling processing line have been in the first level in technology, automatic control, hydraulic transmission, and testing. Along with many kinds of new technology and new process, therefore the quality of the goods could be guaranteed. It has been widely used in home appliance, precise welding tube; flux cored welding wire and etc.

Metal corrugated sheet is also called profiled sheet, which is rolled and cold bended into various wavelike profiled sheet from color coating steel plate, galvanized sheet and other metal sheet.

Aluminum zinc plate surface with smooth, flat and unique gorgeous flowers, color is silver. The special structure of the coating has excellent corrosion resistance.The coating and the adhesion of the film has a good processing performance that can punch, shear, welding etc.Coating composition containing 50-55% aluminum.

Initiated by the automotive industry, zinc alloy deposits (i.e. ZnCo, ZnFe, ZnNi, SnZn) are applied for all applications where the performance expectations exceed 6 years without a change in appearance, and 12 years without functional corrosion. Besides automotive, the electrical, building, aerospace and fastener industries utilize zinc and zinc alloy electrodeposited coatings.

Hot continuous rolling is based on billet �mainly for continuous casting�as its raw material�which is rolled into band steel through roughing mill group and finishing mill group after heating.

Color coating steel plate is hot galvanized plate, aluminum zinc plate, galvanized sheet, cold rolled plate as the substrate, the surface pretreatment (chemical degreasing and chemical conversion treatment), the surface is coated with one layer or several layers of organic coating, and then after curing made products.
