In the manufacturing process of galvalume steel pipes

In the manufacturing process of galvalume steel pipes, the coating composition is made up of 55% aluminum, 43.4% zinc, and 1.6% silicon by weight. When both sides of the 55% aluminum - zinc alloy - coated galvanized steel pipe are exposed to the identical environment, it exhibits superior corrosion resistance compared to a galvanized steel plate of the same thickness.

When both sides of the 55% aluminum - zinc alloy - coated galvanized steel pipe are exposed to the identical environment, it exhibits superior corrosion resistance compared to a galvanized steel plate of the same thickness. This 55% aluminum - zinc alloy - coated galvanized steel plate not only boasts excellent corrosion resistance but also demonstrates outstanding adhesion and flexibility. According to relevant data, the comprehensive anti - corrosion ability of the 55% aluminum - zinc coating is four times that of galvanized steel with the same thickness.

The surface of the galvalume steel pipe features a unique, smooth, flat, and gorgeous star - shaped pattern, with a silver - white base color. Its special coating structure endows it with remarkable corrosion resistance. The normal service life of the galvanized steel plate can reach up to 25 years. Additionally, it has good heat resistance and can be utilized in a high - temperature environment of 315℃. The coating shows good adhesion to the paint film, possesses excellent processing performance, and can be subjected to stamping, shearing, welding, and other operations. Moreover, its surface conductivity is highly efficient.
