This master specification section is intended for use in the preparation of a project specification section covering cold-formed steel exterior wall studs, joists, and trusses, field installed or shop fabricated and field erected. Studs may be either axially-load bearing or non-axially load bearing. Studs for interior partition framing are specified in Section 09 00.
This specification is sponsored by the Supreme Steel Framing System Association (SSFSA) who's members are listed under Part 2 - Products.
Mission: Independent steel stud manufacturing companies with a strong commitment to excellence throughout the United States produce the Supreme Steel Framing System. All Supreme products are certified through IAPMO ER-0313. This product line consists of the same SSMA industry standard products, accompanied by equivalent thickness materials that have been tested for code performance.
Product Certification: SSFSA offers the Code Compliance Certification Program as a means for member manufacturers to certify that structural and non-structural cold-formed steel framing they produce complies with all current code requirements. Certification is independently evaluated.
Sustainability: SSFSA products meet requirements for multiple U.S. Green Building Council LEED credits, per the LEED v4 criteria and beyond. Utilizing SSFSA products on your project will help in achieving Silver, Gold, or Platinum LEED Certification.
