Cold-formed steel framing is a durable, reliable and cost-effective option for low-rise and mid-rise building projects. It typically refers to light-frame construction where the vertical and horizontal structural elements are primarily formed by a system of repetitive framing members. The framing members are typically spaced at 16 or 24 inches on center, with spacing variations lower and higher depending on the loads and coverings.
Wall members are typically vertical lipped channel "stud" members, which fit into unlipped channel "track" sections at the top and bottom. Similar configurations are used for both floor joist and rafter assemblies, but in a horizontal application for floors, and a horizontal or sloped application for roof framing. Additional elements of the framing system include fasteners and connectors, braces and bracing, clips and connectors. Cold-formed steel floor and roof trusses are also available for cold-formed steel framing applications.
This section presents information on the design of structural members that are cold-formed to cross
section shape from sheet steels. Cold-formed steel members include such products as purlins and girts for the construction of metal buildings, studs and joists for light commercial and residential construction, supports for curtain wall systems, formed deck for the construction of floors and roofs, standing seam roof systems, and a myriad of other products. These products have enjoyed significant growth in recent years and are frequently utilized in some shape or form in many projects today. Attributes such as strength, light weight, versatility, non-combustibility, and ease of production, make them cost effective in many applications. This figure shows cross sections of typical products
