AZ stands for aluminum-zinc alloy, which is the material of the steel coating. AZ50 refers to the total weight of both sides of the aluminum-zinc alloy coating in the three-point test in ASTM a972 standard is 0.50 ounces/square foot, which is equivalent to 150 grams/square meter. It is a popular choice for roofing because it is very durable and can be painted in other colors.
AZ50 aluminized zinc is a high quality corrosion resistant steel. It is made of a combination of aluminum and zinc, with an aluminum content of at least 50%. AZ50 aluminized zinc is not only suitable for the exterior of your house, but also for structural purposes and industrial applications. This alloy has many advantages, including excellent strength, impact resistance and excellent weldability.
