The Pacific Steel Casting Company (PSC) is a steel foundry located at 1333 Second Street in West Berkeley, California. It is the third largest steel foundry in the United States, employing 350 people.
The company was founded in 1934 by Douglas Genger and Ivan Johnson who had lost their jobs at General Metals in nearby Oakland as a result of the Great Depression. They bought a steel foundry in West Berkeley that had been repossessed by Wells Fargo, re-opening it as Pacific Steel Casting Company. PSC's business took off with the advent of World War II. The company added another plant in 1974, and a third in 1981.
Pacific Steel lost a third of its workforce in 2011 after a U.S. Immigration and Customs enforcement audit.
In Early 2014, the company filed for bankruptcy protection
