The data in this catalog based on the American Iron and Steel Institure s AISI S100-12 North American Specifi cation for the De-sign of Cold-Formed Steel Structural Members and meets the requirments of the IBC 2015 Building Code.

3 While building codes vary by jurisdiction, this program follows the most recent international standards published by the International Code Council. Material Specifi cationProducts manufactured by SFIA members are formed from Steel with a minimum yield stress of 33 or 50 kips per square inch (ksi). Unless noted otherwise, all products covered in this SFIA catalog are engineered to meet the 2012 edition of the American Iron and Steel Institute (AISI) S100-12, North American Specifi cation of the Design of Cold-Formed Steel Structural Members and other AISI standards referenced in Section 2210 of the 2015 International Building Code (IBC-2012). The structural prop-erties in this SFIA catalog have been computed based on allowable stress design (ASD) which includes distortional buckling considerations for all Stud Sections.

4 For fastener tables, screw sizes and head diameters do not refer to specifi c fasteners which may or may not be available from SFIA member companies. Shear and tension data for screws was developed using published manufacturer data and evaluation reports available at the time of publications.

Back Cover2 Complies with the 2015 International Building Code and AISI S100 General product InformationThe Steel Framing Industry Association (SFIA) supports the industry standard nomenclature published in the American Iron and Steel Institures s (AISI) General Provisions, S200, The AISI S200 states in Section that .. structural members and non-structural members shall use a four-part product designator that identifi es the size (both web depth and fl ange width), style, and thickness. An example of this designator is shown below: EXAMPLE:NOTE: For Structural members 54 mil (16 gauge) and thicker, that have both 33 and 50 ksi yield strength options shown, the designer shall identify which yield strength he has specifi ed and the manufacturer shall label the product with the yield DEPTH:(Example: 3-5/8" = " ~ 362 x 1/100 inches) All member depths are taken in 1/100 inches.

10 For all T Sections, member depth is the inside to inside WIDTH: (Example: 1-5/8" = ~ 162 x 1/100 inches) All fl ange widths are taken in 1/100 : (Example: Stud or Joist section = S) The fi ve alpha characters utilized by the designator system are: S = Stud or Joist Sections T = Track SectionsU = Channel SectionsF = Furring Channel SectionsL = Angle or L-headerMATERIAL THICKNESS: (Example: in = 54 mils; 1 mil = 1/1000 in.) Material thickness is the minimum base metal thickness in mils.
