Cleveland-Cliffs Inc.
A vertically integrated North American steelmaker that mines its own iron ore and turns it into automotive-grade flat-rolled steel for carmakers, plus tubing, tooling, and stamping. Founded in 1847 as the Cleveland Iron Mining Company, it merged with its rival, the Iron Cliffs Company, in 1891 — giving the firm its hyphenated name. It is the oldest iron-mining company in the United States.
