AZ50 galvalume is a high-quality, corrosion-resistant steel. It is made from a combination of aluminum and zinc, with a minimum of 50% aluminum. It's not just for the exterior of your home – AZ50 galvalume can also be used for structural purposes and industrial applications. This alloy has many benefits, including superior strength, impact resistance, and excellent weldability.
AZ50 galvalume is a type of steel that has been coated with aluminum. It's a prevalent choice for roofing because it's incredibly durable and can be painted any color. The AZ stands for aluminum-zinc alloy, which is what the steel coating is made of. Galvanized steel has been dipped in molten zinc to protect it from corrosion. Galvalume is galvanized steel that has also been coated with aluminum.
Galvalume steel refers to 55% Al-Zn coated sheet steels product, which is well suited for roofing and siding applications, as well as automotive, home appliances, furniture, etc. Due to its versatility, durability, beautiful appearance, galvalume steels is favoredbroadly.

Galvalume Coil
feature of galvalume steel coil
Thermal Reflection:
People use it as material for heat-insulation for its thermal reflectivity as high as twice the galvanized steel sheet.
Heat-resistance:
The aluzinc steels sheet could bear above 300℃ high temperature with its good performance in heat-resistance, quite similar to the aluminized steels sheet's performance in oxidation-resistance under high temperature. It is often used for chimney pipe, oven, illominator, and fluorescent lamp cover.
Corrosive-resistance performance:
The essential of galvalume steels coil's corrosive-resistance lies at aluminium's protective property. Once the zinc come under abrasion, the aluminium would form a layer of densified oxidized aluminium, preventing the interior from further corrosion.
Economical:
The density of 55%AL-Zn is smaller than Zn, therefore, with the same weight and thickness of coating, the galvalume steel sheet is 3% larger in area than that of galvanized steel sheet.
Easily painted:
There is perfect adhesiveness between galvalume sheet and paint, saving the process of pre-treatment and weathering for painting work.The coating material on the galvalume steels sheet is outstanding in its adhesiveness, which could be directly tarring on the advertising board and commonly used board with no pre-treatment such as weathering process.
The galvalume steel sheet's surface is luxury in silver colored appearance.
Galvalume steels sheet and galvanized steels sheet are similar in performance of processability and painting.
