The corrosion resistance of 55% galvanized steel is 2-6 times that of galvanized steel. Due to its superior corrosion resistance and processing performance, it can be directly used as building roof panels, civil and household appliances back panels, etc. It is also widely used as a color coating substrate. The smooth production of galvanized steel sheets not only enriches the company's product categories, but also provides more flexible options for future market layout and strategic planning.

　　Aluminized zinc surface coating is composed of 55% aluminum, 43.5% zinc and a small amount of other elements. Microscopically, the surface of the galvanized aluminum sheet has a honeycomb structure, and the honeycomb formed by aluminum contains zinc. In this case, although the aluminum-zinc plate also plays the role of anode protection, on the one hand, due to the reduction of zinc content, on the other hand, because the zinc material is not easy to electrolyze, the anode protection function is greatly reduced. Therefore, once the aluminum-zinc plate is cut, it will quickly rust when the trimming is basically lost. Therefore, the aluminum-zinc plate should be cut as little as possible. Once cut, use anti-rust paint or zinc-rich paint to protect the edges, which can extend the life of the board.

　　The surface of galvanized sheet is more beautiful than galvanized sheet. At the same time, the price of galvanized steel is more expensive than that of galvanized steel, and the price of small spangles is more expensive than that of large spangles.

In cities where the air is humid and rainy, once the galvanized sheet rusts at a certain point, if no measures are taken in time, the place that slowly rusts will become larger and larger, and finally even the entire board surface; but galvanized sheet even at a certain point Rust will not spread.

　　55% aluminized zinc sheet has the barrier protection function of aluminum and the sacrificial protection function of zinc. When zinc is cut or scratched, aluminum will form an insoluble oxide layer, which plays a protective role. In addition, the density of aluminum-zinc plating is low, and the thickness of the plating layer of the same weight is much thicker than that of zinc plating. In addition to corrosion resistance and high temperature resistance, 55% aluminized zinc sheet also has good reflectivity and paint adhesion. There are also 55% aluminized zinc sheets in various spangled states, which are beautiful and suitable for external use.
