Which of the following describes prefabricated studs?

Which of the following describes prefabricated studs?

• A. They are always galvanized or rust inhibiting coated
• B. They must be bare steel
• C. They must be wood
• D. They must be aluminum

Answer: (A)

The main idea is that metal studs used with plaster systems are built to resist moisture and corrosion. Prefabricated studs are typically galvanized or have a rust-inhibiting coating so they won’t rust in damp conditions, moisture from plaster work, or potential leaks. Bare steel would deteriorate quickly and compromise the wall. Wood isn’t used for these metal-framed prefabricated studs in this context, and aluminum isn’t the standard material described here. So the best description is that prefabricated studs are always galvanized or rust-inhibiting coated to protect them in a moist environment.
