Code Approval
The data provided by EB Metal US is based upon the 2012 American Iron and Steel Institute’s S100-12“North American Specification for the Design of Cold-Formed Steel Structural Members” and meets the requirements of the IBC 2015 Building Code, as well as the 2011 California Building Code. While building codes vary by jurisdiction, this guide follows the most recent international standards published by the International Code Council, the most widely recognized building code authority in North America.

General Notes for all Tables
- Where AISI S100-12 Specification is referenced, it is the“North American Specification for the Design of Cold-Formed Steel Structural Members.”
- The strength increase from cold work of forming has been incorporated for flexural strength per section A7.2 of AISI S100-12 Specification.
- The effective moment of inertia for deflection is calculated at a stress which results in a section modulus such that the stress times the section modulus at that stress is equal to the allowable moment. AISI S100-12 specification procedure 1 levels.for service ability Any modified determination values would has be been required used. to Increases be calculated in the by effective a qualified moment engineer. of Inertia (Ixe) may be possible at lower stress
- Various members may be manufactured with yield strengths of 33 or 50 kips per square inch (ksi). The yield strength used for calculations is indicated in the tables.
- For members available in both 33 and 50 ksi, the specifier must clearly indicate which yield strength is required. For example: 362S162-54 (50ksi).
- When provided, factory punchouts shall be located along the centerline of the webs of the members and will have a minimum center-to-center spacing of 24 inches. Punchouts for members greater than 2.5 inches deep are a maximum of 1.5 inches wide x 4 inches long. Members with depths of 1.625 and 2.5 inches and smaller are maximum of 3/4 inches wide x 4 inches long.
- Allowable flexural strength values in the tables are based upon the minimum of local, distortional and lateral-torsional buckling. Distortional buckling strength is based on a k-phi = 0. Higher values may be obtained when sheathing is applied to the walls resulting in a higher k-phi value.
