Company History

1951 – Founded as the Brown Steel Supply Co.

Founded in 1951 by Philip P. and James E. Brown as the Brown Steel Supply Company, California Steel and Tube first specialized in warehousing and metal sheet slitting. By 1954, California Steel and Tube was producing electrically welded steel tubing, by 1959 light roll formed sections, and by 1960 heavy construction shapes.

1986 – Purchased by Ferro Union, Inc.

In 1986, California Steel and Tube was purchased by Ferro Union, Inc., itself a part of the Macsteel International Group. In 2004, when the holding company changed its name to Macsteel Service Centers USA, only California Steel and Tube kept its name because of their strong customer loyalty and regional reputation.

2011 – Acquired by Klockner & Co SE

In 2011, international metals distributor Klockner & Co SE acquired Macsteel Service Centers USA. The combined holdings of Klockner & Co, including the US office of Kloeckner Metals, makes California Steel and Tube part of one of the largest steel distribution companies in North America.
