Product description：

AZ50 means that the total both sides of the aluminum-zinc alloy coating in the  Triple-Spot Test in the ASTM a972 standard are 0.50 oz/square foot, which is equivalent to 150g/square meter.

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 comes in various grades, including AZ50, and AZ70. The rate refers to the thickness of the protective coating on top of the metal: The higher the number, the thicker it is – and therefore, more durable and longer lasting.
