Galvalume Steel Coil

Galvalume Steel Coil Description

Galvanized zinc coil is based on cold-rolled steel plate, which is solidified by 55% aluminum, 43.4 zinc and 1.6 silicon at 600 ℃. It combines the physical protection and high durability of aluminum with the electrochemical protection of zinc. Also known as aluminized zinc steel coil.

The production process of aluminum zinc plating is as follows:
Uncoiling-cleaning-annealing-zinc pot-cooling-air knife-straightening-post-treatment-coiling
Heat Reflection
People use it as a thermal insulation material, and its thermal reflectivity is up to twice that of galvanized steel.
Heat Resistance
Galvanized steel coil has good heat resistance and can withstand high temperatures above 300°C, which is very similar to the oxidation resistance of aluminized steel at high temperatures. Commonly used in chimney tubes, ovens, illuminators, fluorescent lampshades, etc.
Corrosion Resistance
The key to the corrosion resistance of aluminized zinc steel coil is the protective performance of aluminum. Once the zinc is worn, the aluminum forms a dense layer of aluminum oxide, preventing further internal corrosion.
Economy
The density of 55% AL-Zn is smaller than that of Zn. Therefore, when the coating weight and thickness are the same, the area of the aluminum-zinc plated steel sheet is 3% larger than that of the galvanized steel sheet.
Easy to Paint
The coating material on the aluminized zinc steel plate has excellent adhesion, and can be directly coated with tar on advertising boards and common plates without pretreatment such as weathering.
