Cold-formed steel C-studs and joists (SSMA S sections): 162S125 to 1600S350, depth, flange, lip, thickness

What are the dimensions of an SSMA steel stud such as 362S162-54 (depth, flange, lip, thickness, bend radius)? · Standard part · basis: SFIA Technical Guide for Cold-Formed Steel Framing Products (Jan 2026): designation rules, stiffening lip table, thickness table with design inside corner radii; designation list from The Steel Network's Light Steel Framing Members catalog (Form 022015), whose lip and thickness tables are identical

Also called: 362s162-54 dimensions, 600s162-54, 362s125-18 stud size, ssma stud designation, metal stud dimensions, 20 gauge stud 3-5/8, 16 gauge 6 inch stud, steel stud lip size, steel stud inside bend radius, 33 mil stud thickness, c stud step file, cold formed c section

Exact dimensions. Every file is drawn at true size with no tolerance added. The holes and pins that meet another part are listed below under Mating features, with the fit each joint needs; open those by your process's clearance before making the part. Mating features

Notes

  • Designation DDDSFFF-MM: DDD = web depth in 1/100 in (362 = 3-5/8 in; 162 = 1-5/8 in), S = stud or joist with stiffening lips, FFF = flange width in 1/100 in (137 = 1-3/8, 162 = 1-5/8), MM = minimum base-metal thickness in mils. The design thickness (used for every dimension here) is the minimum / 0.95.
  • The lip depends only on the flange: S125 3/16 in, S137 3/8, S162 1/2, S200 / S250 / S300 5/8, S350 1 in. The inside bend radius depends only on the thickness (SFIA thickness table). Web, flange and lip are out-to-out.
  • Drawn areas match SFIA's published gross areas to the third decimal on all files checked (162S125-18 0.080 in², 362S162-33 0.262, 600S162-54 0.556, 600S200-68 0.764, 800S250-97 1.372, 1000S300-118 2.028).
  • Cross-section shown as a 200 mm length, web flat on the bed, no service punch-outs (their size and spacing vary by maker). Table rows are the designations The Steel Network lists; other makers roll other combinations from the same system. The Steel Network supplies its JamStud in place of S350.
  • Track (T sections) for these studs is a separate page: unlipped, with web = stud depth + 2t + R.
