Structural Tee (from S) · AISC Shapes Database v15.0 · United States
ST9X27.35 is a structural tee cut from an S-shape 228.6 mm deep with a 152.4 mm wide flange, weighing 40.7 kg/m. The dimensions below are the published AISC Shapes Database v15.0 values; the drawing is generated from them.
ST tees are cut from S-shapes and inherit the parent’s tapered flange, which the drawing here reproduces.

Derived section properties
Integrated from a square-cornered outline — the fillet radii this family really has are not drawn, so the computed values differ slightly from published. For ST9X27.35 the computed area is 0.54% from published and Ix 0.07%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Sx | 157,481 mm³ |
| Elastic modulus, Sy | 57,894 mm³ |
| Plastic modulus, Zx | 284,121 mm³ |
| Plastic modulus, Zy | 99,469 mm³ |
| Radius of gyration, rx | 71.0 mm |
| Radius of gyration, ry | 29.3 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
