Product Description

Galvalume coil is a kind of aluminum-plated zinc alloy treatment method to form a coil with high strength, excellent corrosion resistance and beautiful appearance on the surface of steel, with high corrosion resistance and air pollution resistance. Galvalume coil also has good surface decoration, and can be processed into a variety of beautiful building and home appliance materials.


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.
