Cold-formed steel (CFS), also known as light-gauge steel, is steel that is shaped at room temperature into thin, strong structural framing components. It is manufactured from flat steel sheet or coil that is bent or rolled into studs, tracks, joists, and other framing members, which increases its strength without adding weight. Cold-formed steel is non-combustible, resistant to termites and rot, and dimensionally stable, meaning it won’t warp, shrink, or twist over time. It is commonly used in residential and commercial buildings for wall, floor, and roof framing, as well as paneled construction systems.
