Throughout our history, innovation has been more than a goal — it’s been a mindset. From the early days of telegraph lines to today’s ever-evolving power and data systems, Copperweld’s forward-thinking approach and innovative products have helped shape the backbone of critical infrastructure. And while the technologies around us have evolved, our purpose remains the same: build smarter wire and cable products that meet the moment — and stand the test of time.

Built on a History of Problem-Solving

Copperweld’s story began with the development of Copper-Clad Steel (CCS), a material that combined the strength of steel with the conductivity of copper. This early innovation offered a durable, efficient solution for grounding and other high-demand applications. In 1918, the first copper-clad ground rod was introduced — and more than a century later, it’s still an industry standard.

Over the decades, we’ve continued to evolve our portfolio to meet the shifting needs of utility, telecom, and construction professionals. Products like ArcAngel^™, Stingray^™ and Sunray^™ were each built around the same principles: purposeful design, reliable performance, and a commitment to solving real challenges in the field.

Today, that same problem-solving spirit drives one of the fastest-growing areas of our business — Copperweld^® Copper-Clad Aluminum (CCA) Building Wire.

A Practical Approach to Modern Wiring

Copperweld^® CCA Building Wire is a bimetallic conductor that blends the conductivity of copper with the light weight and efficiency of aluminum. It’s a code-compliant, UL-listed solution for branch-circuit wiring in both residential and commercial construction.

With copper prices climbing, supply chains tightening, and sustainability demands growing, builders and contractors need practical alternatives to solid-copper wire. CCA building wire delivers a dependable, cost-effective solution that helps manage material costs, supports long-term supply stability, and meets performance expectations — without compromise.

This product reflects what’s always defined Copperweld: using engineering to extend the value of copper, without cutting corners on reliability or code compliance. It’s a solution shaped by the needs of today’s jobsite — efficient, scalable, and ready to deliver.

CCA building wire is playing a bigger role in our future because it meets the challenges of the present. It’s what we’ve always aimed to do — deliver smart, dependable wire and cable products that meet the expectations of engineers, installers, inspectors, and professionals across the industries we serve.

Looking Ahead

As Copperweld celebrates 110 years, we continue to focus on solving problems through innovation. We’re committed to engineering products that serve modern infrastructure — efficiently, reliably, and with an eye toward what’s next.

To everyone who’s been part of our story — customers, partners, and the employees who make Copperweld what it is — thank you. We look forward to the road ahead as we continue to engineer products with purpose, precision, and the kind of lasting innovation that’s defined us for over a century.
