Product Description

Product Description

As the surface coating of AZ50 galvalume steel coil is an alloy composed of aluminum, zinc and other trace elements, it has outstanding corrosion resistance and gradually replaces galvanized coil. The mixed structure of hot dip aluminum zinc silicon coating has its unique advantages in corrosion resistance. 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.
