USS introduces 'ZMAG' coated steel to withstand tough weather

U.S. Steel has rolled out “ZMAG,” a flat-rolled coated steel product intended to endure harsh weather conditions.
ZMAG features a zinc-aluminum-magnesium coating and offers up to five times the corrosion resistance of conventional galvanized steel, according to the Pittsburgh-based steelmaker.
“Whether it’s rain, sleet, or snow, ZMAG coated steel has the toughness to ensure projects are built to last,” James Bruno, SVP of business development and president of USS Kosice, said in a statement on Monday.
Bruno noted that the production process reduces waste and represents U.S. Steel’s commitment to lowering its environmental impact.
USS emphasized that ZMAG offers “a new level of reliability and durability for the solar, automotive, and construction industries.” Specifically, it cited solar frames and racking systems as examples of where it could be used.
The product is “100% domestically produced” as it is melted and manufactured in the US and coated at PRO-TEC in Leipsic, Ohio.
The company noted it is offering an exclusive 25-year warranty on ZMAG steel.
The introduction of ZMAG comes less than a week after domestic mills, including U.S. Steel, filed a trade case against coated steel imports, alleging significant dumping margins and an array of illegal subsidies.
