Copperweld offers a wide range of building wire and cable solutions, including flexible metal conduit, nonmetallic-sheathed cables, and thermoset-insulated wire and cable. As the world’s largest manufacturer of bimetallic conductors, Copperweld produces the genuine Copperweld® brand copper-clad steel wire and the lightweight Copperlite™ copper-clad aluminum wire, which serve as reliable alternatives to solid copper conductors with unique advantages.
Specializing in power and grounding conductors for building construction, power grids, utilities, communications, and transportation, Copperweld has been at the forefront of the industry for over 100 years. The company’s metallurgical expertise and value-engineering approach have led to bimetallic products that revolutionize various industries.
Copperweld’s global network of facilities manufactures bimetallic power and grounding conductors, originating from its main production site in the mid-south, USA. The company operates out of Fayetteville, Tennessee, with a management office in Brentwood, Tennessee, and maintains additional production and distribution facilities in Telford, England, and Liège, Belgium.
Copperweld®’s legacy is one of American innovation and determination. Since its founding in 1915, the company has been driven by a dedicated and determined workforce, which remains the heartbeat of Copperweld®. Engineers at Copperweld® pioneered the process of permanently bonding copper to steel using a molten-weld technique. This process, later replaced by a solid cladding method in 1979, established Copperweld® as a leader in the bimetallic industry.
For over 90 years, genuine Copperweld® copper-clad steel (CCS) wire and strand have been trusted as strong, non-corrosive, and efficient grounding conductors. By combining the strength of steel with the conductivity and corrosion resistance of copper, Copperweld® provides a long-lasting, low impedance path to earth.
