The traditional choice of materials for framing houses is wood. But in commercial construction steel framing is the norm, largely because steel studs are inherently fire-resistant. Steel framing, however, is gradually catching on with home remodelers. It has some real advantages over wood: It is lightweight, inexpensive, and strong. In addition, it won't rot, shrink, or warp (steel framing is ideal for framing walls in a basement, where moisture can create problems).
Walls framed with steel are built in place, one piece at a time. The primary fastener is a sheet metal screw; the primary tools are a drill/driver and metal snips.
To frame a wall with metal studs, expect to spend about 2 to 3 hours for a 12-foot wall. You'll need to plan the wall location and measure the height of the wall in several spots before you begin.
