Hot dip Al Zn steel plate is made of cold-rolled steel sheet with various strength and thickness specifications. Al Zn alloy has excellent corrosion resistance. The hot plated Al Zn alloy is developed successfully on the basis of hot plating aluminum and hot galvanizing technology. It not only has the excellent corrosion resistance, heat resistance and oxidation resistance of the aluminum plating, but also has the excellent electrochemical protection of the galvanized steel plate, so that the notch and scratch are not easy to corrode and rust.

Its main advantages are as follows:

1, The surface is smooth, with excellent resistance to atmospheric corrosion, its corrosion life is 2-6 times higher than that of hot-dip galvanized steel.

2, has a good heat and oxidation resistance, long-term color at 300 °C, about 500 °C long-term use. In addition, the product’s thermal reflectance is higher than 75%, which is twice that of galvanized sheet.

3, with excellent coating and good processing performance. The combination of machine materials is the best choice for color coated steel substrates. Its processability and weldability are similar to those of hot-dip galvanized sheet, and can be processed by cold bending, punching, etc., and have a good appearance.
