What is the maximum allowable length of web holes within steel wall framing studs?

1. 3 inches

2. 4 inches

3. 4 1⁄2 inches

4. 5 inches

The correct answer is: 4 1⁄2 inches

The maximum allowable length of web holes within steel wall framing studs is 4 ½ inches. This specification is critical for maintaining the structural integrity and performance of the steel studs. Holes in the web are necessary for the routing of electrical wiring and plumbing, but if they are too large or too numerous, they can compromise the strength of the stud. A web hole exceeding this maximum length could lead to increased risk of buckling or failure under load because it diminishes the cross-sectional area of the stud that is responsible for bearing weight. Compliance with this regulation helps ensure that the stud can support the demands placed upon it while minimizing risks associated with weakening its structural properties. It’s important to note that while other values may seem viable at first glance, they do not align with the standards established for steel framing. Straying from the specified size could expose a structure to potential safety hazards as the overall strength of the wall assembly may be compromised. Thus, understanding and adhering to the 4 ½-inch limit is crucial for both inspectors and builders.
