Over the past several years, the AISI Committee on Framing Standards (COFS), with oversight from the AISI Standards Council, has worked hard to develop a “whole” document to cover the structural design of cold-formed steel framing. Today, the landscape is much different for cold-formed steel light frame construction. Ten years ago, the AISI standards were compartmentalized into discrete packages on such topics as: general provisions, header design, truss design, structural wall stud design, floor and roof system design, and lateral force resisting system design. Commonly attributed to Aristotle, these words ring especially true when examining the recent evolution of the AISI standards.

ASTM C645 addresses these attributes further in a series of sections, which includes “Materials and Manufacture,” “Dimensions and Permissible Variations,” and “Marking and Identification Requirements.“The whole is greater than the sum of its parts” is an often-used phrase. The four key attributes for architects and specifiers to examine when evaluating non-structural steel stud products are thickness, shape or configuration, coating, and marking or identification.

It is referenced in IBC to determine code compliance for non-structural studs. Until then, guidelines and requirements of ASTM C645 and C754 should be followed.ĪSTM C645, Standard Specification for Non-structural Steel Framing Members, is the current industry standard for the manufacturing of non-structural steel studs. This standard will be adopted in the 2015 International Building Code ( IBC), eventually replacing ASTM C645 as the universal industry standard for the specification of non-structural steel framing. The emergence of the new AISI S220, North American Standard for Cold-formed Steel Framing-Non-structural Members, is also critical. You May Also Like AISI announces winners of research support As specifiers, it is important to understand the material and manufacturing requirements set by ASTM C645, Standard Specification for Non-structural Steel Framing Members, the installation requirements set by ASTM C754, Standard Specification for Installation of Steel Framing Members to Receive Screw-attached Gypsum Panel Products, and the specification of fire-rated partitions.

gypsum board or tile) and providing resistance to limited interior transverse loads.Īccounting for the use of nearly 60 percent of all metal studs in the United States, interior, non-structural wall partitions are common applications for steel framing-specifically light-gauge steel studs. (For more on cold-formed steel, see “ New Purposes for Cold-formed Steel.”) Non-structural steel studs are not designed for bearing any axial loads and are ideal for supporting the dead load typical of many wall finishes ( e.g. The two primary CFS framing applications are structural and non-structural, with this article focusing on the latter.

reduces onsite construction waste as materials can be ordered to specified lengths.Ĭold-formed steel framing products are completely recyclable, and can be locally or regionally sourced for most projects.

Its many performance-based characteristics and ‘green’ attributes have enabled architects to design safe, durable structures that are both dynamic and sustainable. With a history spanning more than a half-century in non-combustible commercial construction, cold-formed steel (CFS) is a popular material choice for framing non-structural interior walls, load-bearing interior and exterior walls, curtain walls, and floor joists.
