Cold-formed steel framing supporting gypsum board must be at least what width in the least dimension?

• A. 2 inches
• B. 4 inches
• C. 6 inches
• D. 8 inches

Answer: (B)

Cold-formed steel framing supporting gypsum board is required to have a minimum width of 4 inches in its least dimension to ensure adequate structural stability and support for the weight of the gypsum board. This minimum width is specified to help prevent bowing or warping of the framing under load, ensuring that the gypsum board remains well-supported and secure on the wall. Additionally, a greater width can provide improved attachment points for the gypsum board, minimizing the risk of failure at the joints and enhancing overall wall performance. The standards in construction practices, particularly in drywall installations, emphasize this width to accommodate various factors, including the weight of the gypsum board itself, as well as the requirements for fastening systems that will hold the board in place effectively. Other options, while potentially suitable for different applications or types of materials, do not meet the minimum requirement for cold-formed steel systems used with gypsum board.
