United States Steel Corporation and DuPont launched a new product, COASTALUME™, North America’s first GALVALUME® material steel designed and warrantied for coastal environments. Marking a collaboration of two American companies, the new COASTALUME product combines the strength and self-healing characteristics of U. S. Steel’s GALVALUME material with DuPont’s Tedlar® PVF film barrier that withstands saltwater corrosion, UV damage, cracking, impact, and more.
Nearly 40% of Americans live in coastal counties and increasingly face unpredictability and damage caused by environmental factors like hurricane force winds and saltwater spray. By combining its materials for the first time, U. S. Steel and DuPont have built a maintenance-free roofing solution that offers a level of durability and reliability in residential and commercial construction along the coast. The addition of a warranty along with a timeless aesthetic increases steel options for builders, architects, and homeowners alike.
