DuPont and United States Steel Broaden COASTALUME™ Product Line with an Exciting New Color Palette

WILMINGTON, Del. June 9th, 2025 – DuPont (NYSE:DD) and U.S. Steel announced the launch of COASTALUME™, a specialized steel solution designed for optimal performance in coastal environments, just over a year ago. The innovative product has garnered interests among roofers facing challenges in sourcing materials suitable for the most demanding conditions, particularly in hurricane and fire-prone coastal regions. COASTALUME™ has proven to meet these critical requirements with exceptional performance and industry-leading warranties. Excitingly, the product line is now set to expand its color palette, adding five new vibrant shades.

The expanded color palette of COASTALUME™ showcases a selection of earthy tones that reflected the latest trends in roofing design, perfectly timed for summer. (*Please note that digital color renderings may vary slightly. You may request physical samples of colors from U.S. Steel or DuPont.)

COASTALUME™ has introduced three core colors: Dawn Gray, Matte Black, and Dark Bronze, which can be found on roofs from Florida to California and even Missouri. In response to the market needs, DuPont™ Tedlar® and U.S. Steel have expanded the color palette to include crisp whites, warm browns, and peaceful blues just in time for the summer 2025 building season. Many contractors have shared their experiences using COASTALUME™, noting its ease of use and the absence of a learning curve, and its capability to withstand the challenges of on-site roll-forming and installation. Most importantly, they cite happy customers who are enjoying their beautiful new roofs that will last decades. 

DuPont™ Tedlar® and U.S. Steel launched these new colors at the FRSA show in sunny Kissimmee Florida last week, showcasing samples and case studies, as well as testimonials with roofers who have used COASTALUME™ in recent projects.

“FRSA is always a great event, and the perfect way to connect face to face with users of COASTALUME™,” said Brian Veeder, Strategic Accounts Director, DuPont™ Tedlar®. “Tedlar® is new to many roofers, and we love to hear directly how this unique product is meeting the challenges of roofing with metal in coastal environments.” 

“Our expanded palette of colors was very well received in Florida, and of course COASTALUME™’s resistance to salt spray, color fade, and chalking were also big topics with the show attendees. We look forward to seeing new projects in some of these beautiful new shades in the near future,” said Stephen Thompson, Regional Sales Manager, U.S. Steel. “Our continued partnership with DuPont and our commitment to driving innovative solutions in roofing continues to open new and exciting conversations with our customers.”

COASTALUME™ is proudly manufactured in the United States and is designed for durability with no maintenance required. It can withstand hurricane-force winds and offers industry-leading warranties on both its steel substrate and Tedlar® finish. Furthermore, the steel is fully recyclable and the Tedlar® coating is a non-PFAS finish, offering long-lasting sustainable solution to commercial building and homeowners alike.
