Cold formed steel framing (also called metal studs or lightweight steel framing systems) makes the steel shapes differently than the hot rolled structural steel. The cold forming process passes steel sheets between large rollers to deform the steel, but at a lower temperature than hot rolling. The rolling process compresses and stretches the steel, hardening it in the process. Most cold rolled steel is either 33,000 psi or 50,000 psi yield strength.
Light gauge steel construction is very similar to wood framed construction in principle – the wooden framing members are replaced with thin steel sections. The steel sections used here are called cold formed sections, meaning that the sections are formed, or given shape at room temperature.
In this and future posts, BuildSteel will be running outtakes from Steel—Doing It Right®, a 13-module course presented by the Association of the Wall and Ceiling Industry. This post reviews steel’s advantages and its sustainability.
Cold-formed steel (CFS) studs are lightweight, easy to handle, install quickly, are noncombustible and save projects time — all reasons that create safer job sites.
