Columbia Steel Company was established around 1909, opening a plant in Pittsburg, California. [a] Iron Trade Review reported in 1917 that the company operated two plants—one in Pittsburg and another in Portland, Oregon. [1]

In early 1923, the company was reorganized as the Columbia Steel Corporation of San Francisco. [2] [4] Later that year, the company acquired a facility from Llewellyn Iron Works in Torrance, California. [5]

Columbia Steel became a subsidiary of U.S. Steel in 1930. [2] The company served as a contractor in the construction of the San Francisco–Oakland Bay Bridge in the 1930s. [3]

The company expanded during World War II but faced a sharp decline in steel production after the end of the wartime manufacturing boom. [2]

Columbia Steel faced a lawsuit from the federal government over its plans to acquire the Consolidated Steel Corporation. The Supreme Court decided in the company's favor in 1948. [6]

In 1952, Columbia Steel merged with Geneva Steel to form U.S. Steel's Columbia-Geneva Steel Division. The division was dissolved in 1964. [7]

In 1986, U.S. Steel entered into a joint venture with Pohang Iron and Steel Company to run its plant in Pittsburg, creating USS-POSCO Industries (UPI). [3]

U.S. Steel regained sole ownership of UPI in 2020. The company announced in 2022 that the Pittsburg facility would be shut down the following year. [8] [9]

Notes

  1. 1 2 A 1917 Iron Trade Review article states that the company was organized in 1909, with offices in San Francisco, as a successor to a prior company in Portland, Oregon. [1] Other sources give the company's date of establishment as 1908 [2] or 1910. [3]
