General Product Information
Introduction
The increasing environmental concerns in the world today have caused us all to examine the way we live. These issues have affected every aspect of our lives, including the materials we use in construction.
The use of cold-formed steel members as a building alternative is an intelligent choice with benefits to, not only the environment, but also to the contractor, designer and developer.
Steel is not only a recyclable product, but also a stronger product allowing for longer clear-spans in the design process. Cold-formed steel is lighter providing ease of handling. It is a straighter product giving a “true” wall with which to work. It doesn’t suffer fluctuation in price, making it easier to bid a project. Quality control is stressed in all phases of the manufacturing process so the highest possible quality is delivered to the job site.
The structural shapes manufactured are easily used for non-structural and structural assemblies, floor and ceiling joist assemblies, and panelized systems. They can be used as the main structural support system or as a supplement to heavy structural steel or concrete construction.
Manufacturers have been producing cold-formed steel framing members for many years, with each manufacturer having its own nomenclature and design values. A steel member with identical properties would be identified by different names based on which manufacturer produced it. This created some confusion at all levels of the construction process.
The SSMA's mission is to proactively represent member firms engaged in the manufacture, marketing and sale of cold-formed steel framing members, as a unified voice to the residential and light commercial
construction industry serviced by its products, which includes contractors, distributors, design professionals, code officials and standards organizations. To this end, SSMA will endeavor to supply products which meet or exceed standards established by national, state and local code bodies and by
recognized industry associations. SSMA resolves to continually initiate and adopt the development of new technology and applications for its members' products with the common goal of growing new market opportunities.
Code Approval
Products manufactured by the members recognized by ICBO Evaluation Service of the Steel Stud Manufacturers Association, SSMA, comply with the Uniform Building Code and International Building Code. See ICBO ES Evaluation Report No. 4943-P.
Material Specifications
Products manufactured by SSMA members are formed from steel with a minimum yield stress of 33 ksi or 50 ksi. All products covered in this catalog are engineered to meet the 1996 Edition of the American Iron and Steel Institute, AISI, “Specification for the Design of Cold-Formed Steel Structural Members.” The structural properties included in this brochure have been computed based on allowable stress design to conform with the same AISI document.

There is new catalog on the SSMA website to download:
http://ssma.com/technical_library.aspx]SSMA Technical Library
This is an updated section properties per new AISI 2008 and IBC2006 and later, CBC 2007 and CBC 2010, too. A must reference for design studs in USA.
Also, the screw and weld capacity is higher compare to the old code, give you some advantage to design a good connections
