Sumiden Wire Products Corporation was the first investment in the United States by Sumitomo Electric Industries (SEI). The investment was made in Stockton, California in 1979 for the production of PC strand. An additional investment was made in Dickson, Tennessee in 1989 for the production of stainless steel wire. The Tennessee facility expanded its products offering  to include PC strand for the East coast market in 1997. In 2016, Sumiden Wire acquired competitor Industrial Alloys to become the largest single stainless steel spring wire producer in the US. And in 2017, Sumiden Wire opened our 3rd PC strand manufacturing plant located in Dayton, Texas to better serve the entire US market from coast-to-coast.
