About Aluminized Zinc Plate
Aluminized zinc plate refers to a steel plate coating that adds aluminum (passivation protection) on top of zinc, with a general composition of 55% aluminum, 43.5% zinc, and 1.5% silicon. It has excellent atmospheric corrosion resistance, which is 2-4 times that of galvanized plate. It also has the high-temperature corrosion resistance of aluminum plate, with a smooth surface and a good appearance.
Usage: Building roofs, walls, electrical cabinets, household appliances, automobiles, color coated substrates, etc
Project Case
Product display
pretreatment
After uncoiling, the steel coil is cleaned and its composition is reduced to the extent that it can be galvanized through the degreasing section and reduction furnace.
Central section
After passing through a zinc pot, a zinc layer is coated on the surface of the steel plate, and then cooled and shaped by a cooling tower.
Post processing
After finishing, straightening, and passivation, it is rolled onto the winding machine to form the final product.

Processing lubrication advantages
Shandong Gangzhijie adopts a two coating and two drying process for the post treatment of aluminum zinc plating, which involves passivation followed by drying and cooling, followed by applying fingerprint resistant and drying cooling. The fingerprint resistant film is thicker and cured more thoroughly, resulting in relatively better processing lubricity.

Cracking degree at the processing bending edge
Shandong Gangzhijie's aluminum zinc coating formula is more advanced. Under the same substrate thickness, strength, material, coating amount, and bending test conditions, the cracking degree and number of cracks in the bending sheet are smaller.
