Leading Corrosion Resistance Will Bring Unprecedented Reliability and Durability to Solar, Automotive, Construction, and More

United States Steel Corporation (“U. S. Steel” or the “Company”) (NYSE: X) today announced the roll out of ZMAG™ coated steel, a revolutionary new carbon flat rolled coated steel product. Engineered to be stronger, more resilient, and more sustainable than existing products on the market today, ZMAG™ steel rises to the challenge of the world’s harshest conditions and introduces a new level of reliability and durability for the solar, automotive, and construction industries.

ZMAG™ steel features a zinc-aluminum-magnesium coating that offers up to five times the corrosion resistance of conventional galvanized steel. ZMAG™ coated steel also remains reliable over time, lowering maintenance costs and increasing efficiency for products that must withstand long-term exposure to the elements like solar frames and racking systems. Melted and manufactured in the U.S. and coated at PRO-TEC in Ohio, ZMAG™ coated steel avoids uncertainties of imported materials by being 100% domestically produced.

“In today’s industrial landscape, the need for materials that can withstand harsh and corrosive environments is more critical than ever,” said James Bruno, Senior Vice President – Business Development and President – U. S. Steel Kosice. “Whether it’s rain, sleet, or snow, ZMAG™ coated steel has the toughness to ensure projects are built to last. With a production process that reduces waste, along with unmatched longevity, ZMAG™ steel also represents U. S. Steel’s commitment to reducing its environmental impact.” In addition to improved strength and flexibility, U. S. Steel is offering an exclusive 25-year warranty on ZMAG™ coated steel.
