California Lathing and Plastering Contractor (C-35 License) Practice Exam

Prefabricated non-load-bearing studs are designed for partitions, not to carry structural loads, so they come in variations that balance strength, weight, and space for utilities. A solid web provides straightforward rigidity and a smooth surface for fastening, which can be desirable in some installations. A perforated web lowers weight and material use while creating open channels that make it easier to run electrical cables or plumbing through the stud assembly. Some product lines also offer different cross-sectional shapes to fit specific framing layouts or attachment methods. Because these systems can combine solid or perforated webs and come in multiple shapes, all of the options listed can apply.
