The Consolidated Steel Corporation was an American steel and shipbuilding business. Formed on 18 December 1928, the company built ships during World War II in two main locations: Wilmington, California and Orange, Texas. It was created by the merger of Llewellyn Iron Works, Baker Iron Works and Union Iron Works, all of Los Angeles. The company entered the shipbuilding business in 1939. In 1948, now a pioneer producer of large-diameter pipelines, Consolidated Steel was renamed Consolidated Western Steel and acquired by U.S. Steel and operated as a wholly-owned subsidiary.
