Cleveland-Cliffs Coatesville

The Coatesville steel plant is one of the oldest continuously operating steelworks in the United States, dating to 1810 when it began as the Brandywine Iron Works, and later becoming Lukens Steel, the first American plant to roll iron plate. Over two centuries it supplied plate for the nation's infrastructure, shipbuilding, and defense. Ownership passed through Bethlehem Steel and ArcelorMittal before Cleveland-Cliffs acquired the site in 2020. Today it produces steel plate from scrap via an electric-arc furnace, with capacity around 800,000 tons a year.
