What are the advantages of aluminized zinc coil? Application of aluminum zinc plating

The surface of aluminum zinc plated steel plate is featured with smooth, flat and gorgeous star flowers, and the basic color is silver white. The special coating structure makes it have excellent corrosion resistance. The normal service life of the aluminized zinc plate can reach 25A, and the heat resistance is very good. It can be used in the high temperature environment of 315 ℃; The coating has good adhesion with the paint film, and has good processing performance. It can be pressed, sheared and welded; The surface conductivity is very good. The advantages are as follows:

1. Corrosion resistance: the aluminized zinc plate has strong corrosion resistance, and the normal service life can reach 25 years, which is 3-6 times longer than the galvanized plate, and is suitable for stainless steel. The corrosion resistance of aluminized zinc plate comes from the maintenance function of aluminum barrier layer and the dedicated maintenance function of zinc. When zinc is cut, scratched and scratched for dedicated maintenance, aluminum forms an insoluble oxide layer, which shows the barrier maintenance function. The aluminum zinc alloy steel coil has been exposed to different atmospheric environments for more than 20 years. It has been proved that the trimming maintenance function of 55% aluminum zinc alloy steel plate is better than that of galvanized steel plate and 5% aluminum zinc alloy steel plate.

2. Heat resistance: the aluminized zinc plate has a high thermal reflectivity, which is suitable for roof data. The aluminized zinc alloy steel plate has excellent heat resistance and can be used in high temperature environment up to 315 degrees.

3. Recoating property: (adhesion of paint film) the aluminum zinc plate can maintain excellent adhesion with the paint film, and can be directly painted or sprayed without special pretreatment.

4. Corrosion resistance after coating: after local coating and baking, the corrosion resistance of the aluminum zinc plate without coating decreases little. The function is much better than electroplating color zinc, electro galvanized sheet and hot-dip galvanized sheet.

5. Machinability: (shearing, stamping, spot welding, seam welding) the aluminum zinc plated steel plate has excellent processing functions, can be pressed, sheared, welded, etc., and the coating has good adhesion and impact resistance.

6. Conductivity: the surface of aluminum zinc plate is treated by special wax coating, which can meet the requirements of electromagnetic shielding.
