Galvalume steel is an ideal roofing material because of its strength, extraordinary outdoor corrosion resistance and longevity. Steel roofing used in residential applications today is metallic coated with either Zinc (G90) or Zinc/Aluminum (AZ50) to provide the corrosion resistance contractors & homeowners desire. Steel roofing is strong and therefore gives higher wind uplift resistance and a broader range of application than other roofing materials. As a result, an installed steel roof system has a broader range of price levels and products than many other kinds of metal roofing. Steel roofs have passed the UL 90 wind tests due to their strength and weight. Today's quality steel roofing offers excellent rust protection as well. Galvanized steel roofing is available painted, aggregate-coated, or with a mill or bare finish. Unlike conventional non-metallic roof systems, Galvalume steel roofs won't crack and peel when subjected to the sun and weather.
