![]() Nearly all steel-based products will experience some level of normal edge creep from the exposed steel when the coil is cut, but it is minimal and will eventually stop with Galvalume. Galvalume’s self-healing characteristics help control the red rusting at any cut/exposed edges. That’s why Galvalume’s corrosion resistance is about two to four times better than galvanized steel. Keep in mind that in 20, steel prices continually fluctuate and vary dramatically.Ĭorrosion resistant – Galvalume’s chemical formula was specifically designed to combine the toughness, strength, and self-healing properties of zinc with the rust-resisting properties of aluminum. Least expensive – Compared to other high-quality metal roofing materials, Galvalume costs the least amount of money. Depending upon the thickness, color, and quality of the desired Galvalume panels, pricing ranges anywhere from $5.00 to $15.00 per square foot. This process allows Galvalume to have some of the best characteristics of each metal, which is why it’s one of the most popular metals used in metal roofing. To create Galvalume, mills begin with a cold-rolled carbon steel base sheet that is then continuously hot-dipped with aluminum and zinc alloys (AZ) until it reaches a coating of 55% aluminum, 43.4% zinc, and 1.6% silicone. Galvalume, a flat rolled steel-based metal roofing material, combines three of the most high-performing metallic coatings used in roofing today - steel, aluminum, and zinc. Galvalume® Metal Roofingīethlehem Steel introduced the Galvalume coating to the construction industry in the early 1970s.
