What is the center to center spacing of holes in steel wall studs?

A. 12 in.
B. 16 in.
C. 20 in.
D. 24 in.

The correct answer is: B. 16 in.

The typical center-to-center spacing of holes in steel wall studs is 16 inches. This standard is widely used in both steel and wood framing to ensure compatibility with standard building materials such as drywall, insulation, and other wall coverings, which are also designed with a 16-inch on-center layout in mind. This spacing helps in maintaining structural integrity while also facilitating electrical and plumbing installations that are designed to fit within these space allowances. The selection of 16 inches as a standard provides adequate support for the wall system while keeping materials efficient and cost-effective. Thus, using 16 inches allows for easier calculations during the construction process, helps to standardize framing practices, and ensures that the wall finishes can be applied uniformly across different types of construction settings.
