United States Steel Corporation has announced a doubling of the standard limited warranty policy for GALVALUME coated coils used in nonresidential and residential building construction. The new warranties provided to US Steel customers will range from 40-60 years, a significant upgrade from the existing 20-25 year warranties. The new warranties apply to coils shipped on or after 1 January 2023, with heavier coating weights receiving longer warranties. Pre-painted products receive an additional 10 years of coverage. GALVALUME is a registered trademark of BIEC International Inc.US Steel said “US Steel's new warranty policy responds to the needs of consumers and our customers alike, further supporting the growth of corrosion-resistant sheet steels in building construction. These longer warranties can provide builders with confidence that GALVALUME® coated steel will have superior and lasting performance and withstand Mother Nature’s most extreme events like hurricanes, heavy snowfall, and wildfires.”US Steel has been coating GALVALUME steel for more than 40 years and is the most experienced and longest tenured licensee of GALVALUME coated steel coils in North America. GALVALUME coated steel is a preferred alternative to zinc-aluminum coated steel because the latter is often unlicensed and imported into the U.S. construction market and may not meet the same performance standards or have the same complex coated microstructure as GALVALUME.
