Product Identification
All SSMA products have a four part identification code which identifies the size (both depth and flange width), styles and material thickness of each number.
| Member Depth: | Flange Width: | Style: | Material Thickness: |
|---|---|---|---|
| (Example: 6″= 600 x 1/100 inches) | (Example: 1-5/8″= 1.625″= 162 x 1/100 inches) | (Example: Stud or Joist Section = S) | (Example: 0.054 in. = 54 mils; 1 mil = 1/1000 in.) |
| All member depths are taken in 1/100 inches. For all “T” sections member depth is the inside to inside dimension. | All flange widths are taken in 1/100 inches. | The four alpha characters utilized by the designator system are: S = Stud | Material thickness is the minimum base metal thickness in mils. Minimum base metal thickness represents 95% of the design thickness. |
