Designing With Cold-Formed Steel Framing: Test What You Know
Getting ready to design a cold-formed steel (CFS) framed building? Answer the following questions to make sure you’re prepared to design successfully.
Incorrect: While consulting your local building department can be helpful, you may actually need to provide them with the most updated CFS framing standards. A local building department may only have the editions referenced in the building code that is currently adopted in its jurisdiction, which may not be the most updated version.
Incorrect: The International Code Council’s “International Building Code and International Residential Code” generally references the CFS framing standards developed by the American Iron and Steel Institute. However, it may not reference the most updated editions of the CFS framing standards. There is typically a lag between the completion of a new edition of a CFS framing standard by AISI and the publication of the ICC codes.
Correct! The most updated CFS framing standards are available for free download from the Cold-Formed Steel Engineers Institute at
www.aisistandards.org.
This is False. Like any premanufactured structural component, CFS panels require engineered drawings and layouts for approval by the authority having jurisdiction.
This is True. Building CFS components off-site in controlled environments can help reduce construction delays due to weather.
This is True. This allows panels to be fabricated to exact standards, which can help reduce material waste.
Incorrect. 43 represents minimum base steel thickness in mils (1/1000 inch). However, this thickness represents minimum delivered thickness — not design thickness. Industry practice recognizes that the minimum base steel thickness represents 95 percent of the design thickness.
In the example given, 350 represents the flange width of 3-1/2 inches, S represents that the section is a stud, and 162 represents the flange width of 1-5/8 inches. The CFS product designator system is defined in several of the AISI CFS framing standards.

Incorrect. The reviewer at your local building department can perform a plan check to verify that your designs are accurate and meet local code requirements.

B. CFS framing has a proven track record of providing cost-effective benefits over the entire construction cycle due to lower insurance rates, shorter project cycles, predictability and accuracy of steel components, and improved design efficiency.
A. CFS framing can’t burn and does not contribute to fire growth or spread. Insurers traditionally offer steel-framed structures lower builders risk and general liability premiums compared to structures framed with wood.
Before we reveal your overall score, tell us a little bit about your experience with CFS framing.
C. Every piece of cold-formed steel contains recycled content and meets the highest sustainability requirements of all major green building standards and rating programs.
D. The durability of CFS framing, including its resistance to corrosion, mold, and vermin, gives it a longevity that few building materials can rival.
