Copperweld^® Building Wire Manufacturing and Testing Facilities

About this video

Every foot of Copperweld^® Copper-Clad Aluminum (CCA) Building Wire has a story. This tour follows that journey from raw materials through manufacturing and testing, providing an inside look at the people, processes, and technologies behind the product. Whether you're an engineer, contractor, distributor, inspector, builder, or simply interested in how CCA building wire is made, this video offers a closer look at the standards and quality systems that guide every stage of production.

The journey begins long before the conductor reaches a production line. It starts with carefully selected raw materials that are verified for chemical composition, dimensional accuracy, and electrical performance before they ever become part of a Copperweld conductor. From there, you'll follow the creation of Copper-Clad Aluminum rod as copper and aluminum are permanently bonded together, then watch as the conductor is drawn, annealed, insulated, and assembled into finished building wire.

Along the way, you'll see how continuous in-line monitoring and off-line quality checks verify everything from conductor dimensions and copper thickness to insulation integrity and overall construction. Rather than relying on a single inspection at the end of production, quality is continually verified throughout the manufacturing process.

The tour concludes inside Copperweld's Compliance and Performance Laboratories, where building wire is evaluated against the requirements of nationally recognized safety standards and subjected to demanding performance testing that simulates years of service in the field. Together, these manufacturing processes and testing programs provide a deeper understanding of the engineering, quality systems, and commitment to continuous verification behind every foot of Copperweld CCA Building Wire.
