General Cold-Formed Steel Framing FAQs
What standards govern the manufacture and physical requirements of cold-formed steel products?
What is an Equivalent (EQ) Drywall Stud?
For interior framing, what is the difference between composite and non-composite limiting heights tables?
When is it required to use lateral bracing on an interior wall?
What are the bracing requirements for curtain wall framing?
What are the bracing requirements for combined (axial and transverse) loaded studs?
What are the bracing requirements for floor joists?
What fire/sound rating can be achieved while providing cold-formed steel framing in wall, floor or ceiling assemblies?
In an engineering sense, when is 50ksi material required in lieu of 33ksi material?
What allowable deflection should be specified for curtain wall applications?
What floor live load should I use for a joist application?
If stamped shop drawings are required for the project, how much time is required to get a full engineering package with a state stamp?
What determines whether or not punched versus unpunched webs should be provided?
I am building a steel joist/load-bearing wall system. Do the joists need to be in line with the load-bearing studs below?
Are screw connections required by the industry instead of welded connections?
What are the basic functions of the AISI and ASTM organizations and standards as they apply to the cold-formed / light gauge steel framing industry?
What protective coatings are acceptable for cold-formed / light gauge steel framing in the United States?
Is it required that stud and track framing members be marked?
I am an architect writing my own master specification. Any advice for how to determine what potential stud manufacturers are acceptable?

Content: In addition, joist bridging should start and end with two (2) spaces of solid bridging. Between the start and end spaces, a repetitive pattern of five (5) spaces of strapping, on the laterally unbraced flange, followed by one space of solid bridging can be used. Joist bridging should be placed as follows: Span Bridging Required
< 14 ft one row at mid-point
14 to 20 ft two rows at third points
over 20 ft one row every 6 ft
See our lateral bracing details in our CAD Framing Details for more information. What fire/sound rating can be achieved while providing cold-formed steel framing in wall, floor or ceiling assemblies? Since the steel stud or floor joist is one part of a wall or floor/ceiling system, actual wall and floor assemblies are tested for their fire resistance while maintaining their structural integrity by various approved testing agencies throughout the country. For interior framing reference ProSTUD's UL & STC Ratings web site. See our Fire & Acoustic Support Docs web page for other resources. In an engineering sense, when is 50ksi material required in lieu of 33ksi material? The 33ksi or 50ksi refers to the "grade of steel" or its yield point.
