Metal studs save money and are easy to install. Metal studs have precut holes designed to accommodate electrical and plumbing lines. When running NM cable through metal framing, inspect the holes to be sure there are no rough or sharp edges that could damage insulation. Always use the special bushings designed to protect wiring.
