Steel wall framing track shall have a minimum flange width of ____?

Steel wall framing track shall have a minimum flange width of ____?

• A. 1 inch
• B. 1-3/8 inch
• C. 1-1/2 inch
• D. 1-1/4 inch

Answer: (D)

The key idea here is that the track’s flange width determines how much surface area is available to fasten the track to the studs and to carry fasteners for drywall and panels. A minimum flange width of 1-1/4 inch provides enough bearing surface for screws or nails to securely attach the track to the studs and for drywall screws to seat properly without tearing or pulling through. It also helps keep the wall assembly flush and correctly aligned during installation. Other widths are either too narrow to allow reliable fastening (which can lead to misalignment or pull-out under load) or are used in heavier-duty applications, but 1-1/4 inch is the standard minimum for typical steel wall framing.
