Both these products are registered trademarks of U S Steel. The galvalume product is a combination of aluminum and zinc at a ratio of 55% to 45% and applied to carbon steel through a hot dip process. Both the aluminum and the zinc combine to provide excellent corrosion resistance and protection to the steel sheet. The unique makeup provides protection even after the shearing, drawing, breaking, or forming fabrication process.
Acrylume offers an additional protection to the galvalume sheet. A clear, organic resin is roll coated onto the surface of the galvalume product. The result is a thin layer of acrylic that is formed onto both sides of the sheet creating an even longer lasting, corrosion resistant product.
