Structural Tee (from S) · AISC Shapes Database v15.0 · United States
ST2.5X5 is a structural tee cut from an S-shape 63.5 mm deep with a 76.2 mm wide flange, weighing 7.4 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 ST2.5X5 the computed area is 1.12% from published and Ix 1.62%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Sx | 5,791 mm³ |
| Elastic modulus, Sy | 6,714 mm³ |
| Plastic modulus, Zx | 10,648 mm³ |
| Plastic modulus, Zy | 11,198 mm³ |
| Radius of gyration, rx | 17.5 mm |
| Radius of gyration, ry | 16.6 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
