Common standard web sizes for steel studs include: 1 5/8, 2 1/2, 3 1/2, 3 5/8 and 4 inches. Additional sizes are 5 1/2, 6, 8, 10, 12 and 14 inches. The stud width, also known as the "web," is the primary dimension used for size identification and selection.
The load-bearing capacity of a steel stud varies according to its dimensional features. Flange width, metal gage and length are required after selection of the desired web width in order to identify an appropriate stud for an application.
Steel studs are produced in sizes that are similar to dimensional lumber but have several advantages compared to wood. They are consistently uniform in straightness, do not warp or shrink, can be made from recycled material, produce less construction waste, and are not subject to termite damage. They also contain no volatile organic compounds used in treating wood. Steel studs are commonly available with pre-punched holes in the web for convenient routing of electrical and plumbing lines.
