Copperweld Steel Company
The Copperweld Steel Company began manufacturing copper-covered steel wire in 1915 as the Copper Clad Steel Company. After Jacob Roth's invention of copper welding to reduce conductability loss, Copperweld became the standard for electrical cable and telephone wire used in the United States. After a fire destroyed the Rankin, Pa. facility in 1923, Copperweld opened a new plant in Glassport, ten miles down the Monongahela River in 1927. Part of the New Deal, the Rural Electrification Program revitalized a sluggish industry. The Company now has its world headquarters in Warren, Ohio.
