U. S. Steel And DuPont™ Launch COASTALUME™ For Coastal Environments

Combines U.S. Steel’s GALVALUME® with DuPont™Tedlar® PVF Film

Pittsburgh, PA and Wilmington, DE - United States Steel Corporation (NYSE: X) and DuPont (NYSE: DD) announce the launch of COASTALUME™, North America’s first GALVALUME® material designed and warrantied for coastal environments. Marking a collaboration of two iconic American industry leaders, the new COASTALUME™ product combines the strength and self-healing characteristics of U. S. Steel’s GALVALUME® material with DuPont™Tedlar® PVF film barrier that withstands saltwater corrosion, UV damage, cracking, impact, and more. The jointly designed product is exclusively available through U. S. Steel.

Today, nearly 40 percent (according to data from the National Ocean Service) 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 these two materials for the first time, U. S. Steel and DuPont have set out to build a maintenance-free roofing solution that offers a level of durability and reliability needed in residential and commercial construction along the coast. It was noted that the addition of a best-in-class warranty along with a timeless aesthetic, including a wide variety of color and finish options, further elevates steel options for builders, architects, and homeowners alike.

“American-made steel stands above steel made anywhere else, and steel is infinitely recyclable, unlike other building materials,” said Robert Kopf, Vice President Sales and Marketing, at U. S. Steel. “With our new product COASTALUME™ we were able to combine our steel with the proven performance and durability of DuPont™ Tedlar® PVF film, and fully address the unique needs of coastal construction, which must withstand the toll that wind and saltwater inflict over time. This was engineered to address that need head-on.”

Applied directly to the steel coil, Tedlar® film excels in resisting sea water and salt spray, maintaining color integrity even in prolonged sun exposure. Available in over 30 different colors, including metallics, wood grains, and stone finishes, it combine durability and versatility.

“DuPont invented Tedlar® over six decades ago, and today it remains the industry gold standard in protection because of its flexibility, durability, and reliability,” said Matt Urfali, Vice President Sales and Marketing, DuPont™ Tedlar®. “Tedlar’s performance and ease of maintenance have rightfully driven several exciting applications over the years, including use by the solar industry, aerospace, and even NASA. Now, by combining the resilience and flexibility of Tedlar® with the strength of U. S. Steel’s GALVALUME® material, this is the next breakthrough for the demanding construction market along the coast.”

COASTALUME™’s product warranty uniquely covers roofing and siding products installed up to 300 feet from breaking surf, large bays, marshes, and other coastlines. The exclusive warranty also covers up to 50 years for finish warranty and 25 years for substrate.

DuPont and U. S. Steel have more than 340 years of combined science and manufacturing excellence in the United States. COASTALUME™ product is being unveiled at the 2023 METALCON Industry Trade Show, being held October 18-20 in Las Vegas, NV, by representatives from both U. S. Steel and DuPont. GALVALUME® material is a registered trademark of BIEC International Inc.
