Although metal framing studs are available in many different sizes, there are five sizes that are most commonly used: 1 5/8 inches, 2 1/2 inches, 3 5/8 inches, 4 inches and 6 inches. Of these five sizes, 3 5/8 inches is used the most.
For commercial and industrial applications, metal framing studs have replaced the wood framing studs typically used in residential construction. Metal studs offer several advantages over wooden studs; primarily, ease of installation, uniform sizing and resistance to warping. In addition, metal framing studs are easier to install, which greatly reduces the amount of time required to frame a building.
