<br />Light Gauge/ Cold -Formed Steel Standards
<br />• ASTM a653: grades 33, 27,40 & 50( Class 1 and 3)
<br />• ASTM A792: Grades 33, 37, 40, 50A.
<br />• ASTM A875: grades 33, 27, 40 & 50
<br />Universal Designation for Light gauge/ Cold -formed Steel
<br />Light gauge/ cold formed steel code: The steel stud Manufacturers Association ( SSMA) has
<br />published a catalog using a new designator system called "The right STUF". The intent of the new
<br />designators is to make steel framing products easier to use and to accelerate their acceptance in new
<br />markets.
<br />• S: Stud or joist section with flanges stiffeners/lips, C-shapes.
<br />• T: track sections.
<br />• U: cold -rolled channel or channel studs, without the stiffeners/lips.
<br />• Furring channels, or hat shapes.
<br />For members in residential projects where the material presented in the IRC doesn't give an answer
<br />and for commercial projects, the International Building Code, IBC must be used. The IBC
<br />references the Cold -Formed Steel Design, AISI Manual, by American Iron and Steel Institute.
<br />Standard Shapes
<br />The C-shaped is used the most for the structural members such as studs, floor joists, roof rafters,
<br />roof trusses etc. The C-shaped section must have stiffeners/ lips with specified length/width to
<br />prevent local buckling. Please see the figure below
<br />3. Section Designation and Properties
<br />THE Right STUF:
<br />Universal Designator System for Light Gauge Steel Framing Members
<br />The Right STUF will identify any common light gauge steel framing member using:
<br />• Web Depth (D), expressed in 1/100th inches.
<br />• Flange Width (B), expressed in I/100th inches.
<br />• Minimum Base Metal Thickness (T), expressed in mils (1/1000th inches), and the following
<br />designators,
<br />* S = Stud or Joist Sections with Flange Stiffeners (C-Shapes)
<br />* T = Track Sections
<br />U = Cold -Rolled Channel or Channel Studs (w/o Flange Stiffeners)
<br />F = Furring Channels
<br />For sections available In both 33 and 50 ksi, the specifier must clearly indicate which yield point Is required when ordering.
<br />For example: 60OS162-54 (50 ksi).

<br />Nomenclature Example
<br />All SSMA products have a four-part identification code that identifies the web depth, flange width, style, and mill thickness.
<br />Member Web Depth Flange Width
<br />(Example: 6" = 600 x 'loco inch) (Example: 1 W - 1.625" a 162 x t/eao Inch)
<br />All member depths are given in a/lase inch. All flange widths are given In '/ore Inch.
<br />For all "T" sections, member depth is the
<br />inside to inside dimension.
<br />Style
<br />(Example: Stud or Joist section = S)
<br />Nomenclature uses the following four
<br />characters to designate the profile:
<br />S_
<br />Stud or Joist Sections
<br />T = Track Sections
<br />U - Channel Sections
<br />F = Furring Channel Sections
<br />— 54
<br />Mil Thickness
<br />(Example: 0.054' - S6 mils; 1 mil - Viam inch)
<br />Mil thickness is the minimum base steel thickness
<br />measured in'/j000 Inch. Minimum base steel
<br />thickness represents 95 percent of the design
<br />thickness.
<br />EXAMPLES:
<br />Designation for a 5-1/2%16 gauge C-shape with 1-5/8" flanges and 1/2" stiffening lip = 550S162-54 54
