Introduction
Galvalume® (AZ) steel is a coated product contains approximately 55 percent aluminum, 43 percent zinc, and 2 percent silicon. Major applications are for metal building components, including roofs, side sheets, and structural members. The coating weight of the product is preceded by "AZ", which is the designation for Galvalume®. Uses are for exposed and unexposed surfaces. Galvalume® has superior corrosion resistance and is utilized almost exclusively in the light construction industry.
