National Steel

Less than two weeks after the great stock-market crash, National Steel Corporation was formed by the merger of three companies - Weirton Steel, Michigan Steel and MA Hanna Steel. Weirton Steel received 50% of National stock and Ernest T. Weir became Chairman and chief executive. Headquarters were located in Pittsburgh, Weir's hometown. The other parent companies, Michigan Steel and M. A. Hanna, got 25% each of National.

In 2003, the United States Steel Corporation purchased a great number of the assets of the National Steel Corporation which had filed for bankruptcy in 2002. These assets included Great Lakes Steel, in Ecorse and River Rouge, Michigan; Granite City Steel in Granite City, Illinois; the Midwest finishing facility in Portage, Indiana; ProCoil Corporation in Canton, Michigan; National Steel Pellet Company in Keewatin, Minnesota; and various other subsidiaries and joint-venture interests, including a 50 percent equity interest in Double G Coatings, in Jackson, Mississippi.
