Cold-formed steel track (SSMA T sections): 162T125 to 1600T200, web, leg, thickness, bend radius — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/cold-formed-steel-track-ssma/ (sheet CC BY 4.0) 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) Catalog version: 2026-10-20 Overall (mm): length 200.0 - 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. designation nominal depth in web out-to-out in leg in mils ref. gauge design t in inside R in
