Galvalume Steel Coil China Manufacturer
Galvalume coil is a product that is coated with a layer of aluminum-zinc alloy on the surface of steel plate. This alloy is usually composed of 55% aluminum, 43.4% zinc and 1.6% silicon.
Basic composition:
Substrate: Generally cold-rolled steel coil, with good mechanical properties and processing properties.
Coating: Aluminum-zinc alloy coating, usually composed of 55% aluminum, 43.4% zinc and 1.6% silicon, forming a dense alloy layer, providing excellent protection.
Galvalume coil combines the advantages of aluminum and zinc, with excellent corrosion resistance and high temperature oxidation resistance.

Excellent Corrosion Resistance
The aluminum-zinc alloy layer has good corrosion resistance, which is 2-6 times that of galvanized steel coils, and is particularly suitable for harsh environments.
High Temperature Oxidation Resistance
The aluminum-zinc coating can form a solid layer of aluminum oxide at high temperatures to protect the substrate from oxidation, and its heat resistance is better than that of galvanized coils.
Excellent Appearance
The surface is smooth and flat, with a beautiful silver-white metallic luster, suitable for products with high appearance requirements.
Good Processing Performance
It can be processed by shearing, stamping, bending, etc., to meet the needs of various manufacturing processes.

More Information
Galvalume Steel Coil Production Process
1. Cleaning and pretreatment: The steel coil undergoes pretreatment processes such as cleaning and pickling to ensure that the surface is clean and free of oil stains.
2. Hot-dip aluminum-zinc plating: The pretreated steel coil is immersed in the molten aluminum-zinc alloy liquid, and the alloy layer is evenly attached to the surface of the steel plate through the hot-dip plating process.
3. Cooling and solidification: The coated steel coil is cooled and solidified to form a dense coating structure.
4. Post-treatment: Passivation treatment, oil coating treatment, etc. are carried out as needed to improve the corrosion resistance and surface quality of the product.
