Nailable studs must always be which of the following?

Nailable studs must always be which of the following?

• A. Galvanized
• B. Rust-inhibitive coating
• C. Both galvanized and rust-inhibitive coating
• D. Neither

Answer: (C)

Corrosion protection for metal studs used with plaster is the key idea. These studs sit in a damp, alkaline environment, so they must be shielded against rust. Galvanizing coats the steel with zinc, which provides strong rust resistance by protecting the underlying metal. In some standards and real-world practice, an additional rust-inhibitive coating is applied to reinforce protection, especially in tougher moisture or chemical conditions, or where the coating might be damaged. Together, having both galvanizing and a rust-inhibitive coating maximizes durability and prevents rust bleed-through into the plaster.
