StructureCalcsST4X9.2
Structural Tee (from S) · AISC Shapes Database v15.0 · United States
ST4X9.2 is a structural tee cut from an S-shape 101.6 mm deep with a 101.6 mm wide flange, weighing 13.7 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 ST4X9.2 the computed area is 1.20% from published and Ix 0.54%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Sx | 18,816 mm³ |
| Elastic modulus, Sy | 15,461 mm³ |
| Plastic modulus, Zx | 33,961 mm³ |
| Plastic modulus, Zy | 25,969 mm³ |
| Radius of gyration, rx | 29.1 mm |
| Radius of gyration, ry | 21.4 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
