Screw studs for non-load-bearing partitions must be fabricated of ______ shaped metal channel:

• A. I-shaped
• B. U- or C-shaped
• C. L-shaped
• D. T-shaped

Answer: (B)

For non-load-bearing partitions, you want a light, easy-to-install framing member that provides solid screw surfaces for the wallboard on both sides. A screw stud made from a U- or C-shaped metal channel fits that need perfectly. The channel cross-section gives two edges (the flanges) that Gypsum boards can be fastened to securely, while the open face allows convenient access for wiring and services inside the wall cavity. This shape supplies enough rigidity for thin partitions without carrying structural loads, and it’s lighter and more economical than heavy I-shaped studs. In contrast, I-shaped members are structural and heavier, intended for load-bearing frames; L-shaped and T-shaped forms aren’t suited to vertical stud behavior or to providing a continuous, screw-friendly edge for drywall on both faces.
