Cold-formed steel track (SSMA T sections): 162T125 to 1600T200, web, leg, thickness, bend radius

What are the dimensions of SSMA steel track such as 362T125-54 (web, leg, thickness, bend radius)? · Standard part · basis: SFIA Technical Guide for Cold-Formed Steel Framing Products (Jan 2026): designation rules, thickness table, track web-depth rule and (T) Track Section Properties table; cross-checked on ClarkDietrich's 925T125-54 submittal (web depth 9.448 in = 9.25 + 2 × 0.0566 + 0.0849)

Also called: 362t125-54 dimensions, 600t125-54, metal stud track dimensions, steel track 3-5/8, track leg 1-1/4, ssma track designation, track web depth, deflection track 2 inch leg, steel runner channel size, track step file

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 DDDTFFF-MM: DDD = depth in 1/100 in (the stud size it takes; for T sections SFIA says member depth is the inside-to-inside dimension), T = track, FFF = leg (flange) length in 1/100 in (125 = 1-1/4, 150 = 1-1/2, 200 = 2 in), MM = minimum thickness in mils.
  • SFIA computes track properties with web depth = nominal stud width + 2 × design thickness + bend radius, which leaves an inside width of D + R. The files are drawn that way, and the drawn areas match SFIA's published gross areas (362T125-54 0.346 in², 600T125-54 0.480, 362T150-33 0.229, 600T200-68 0.712, 1000T150-97 1.320).
  • Legs are out-to-out from the bottom of the web; inside radius R by thickness as on the stud page. Cross-section shown as a 200 mm length, no punch-outs. The 10 in file is wider than a 256 mm printer bed.
  • Rows are SFIA's track table. The text of the 1200T125/T150 rows was read up to 97 mil; check the guide for 118 mil at those sizes.

Questions

Will a 3-5/8 in stud fit in 362T125 track?

Yes. The track's inside is 3-5/8 in plus the bend radius, so the 362S stud slides in with its flanges against the legs.

What is the web depth of 362T125-54?

3.823 in out-to-out (3.625 + 2 × 0.0566 + 0.0849), per SFIA's track rule.

What leg lengths does steel track come in?

1-1/4 in (T125), 1-1/2 in (T150) and 2 in (T200) in SFIA's tables; longer legs are deflection track.
