Residential Construction

Upgrade your building wire

The electrical demands of residential construction are evolving, and so are the materials behind them.

Builders and electrical contractors must balance tight project budgets, efficient installation, and protection against material loss that can disrupt cycle times. Copperweld Copper-Clad Aluminum (CCA) Building Wire supports these demands by helping teams stabilize material costs, reduce theft incentives, and streamline installation across residential projects.

As the global leader in bimetallic conductor technology, Copperweld brings more than a century of metallurgical expertise to residential building — delivering wire solutions designed to help crews stay on schedule, control material costs, and avoid disruptions that impact project timelines.

Smarter building comes down to the wire
