Galvalume is an aluminum/zinc coated carbon steel product that was designed specifically for building products and contains approximately 80% aluminum in the coating by volume. Galvalume offers much better cut edge protection than traditional hot dipped galvanized products. It carries a 25 year warranty against perforation.
Aluminum Substrate:
Our aluminum products are painted over prime, made in the USA, aluminum. We use multiple alloys and tempers to ensure that the products supplied will meet and/or exceed your requirements. We are big fans of using our painted aluminum products for coastal applications and have invested a lot of R&D funds to ensure our aluminum roof systems meet and/or exceed the high wind requirements. Our painted aluminum in salt environments does carry a 25-year warranty, however there are annual maintenance requirements.
Drexlume® Substrate:
Drexlume is our version of mill finished Galvalume® with a two-sided, clear acrylic finish that is installed as a unpainted product. The clear acrylic is there to aid with roll forming and will weather away over time (no impact to the performance).
