Structural Tee (from W) · AISC Shapes Database v15.0 · United States
WT6X68 is a structural tee cut from a W-shape 170.4 mm deep with a 315.0 mm wide flange, weighing 101.2 kg/m. The dimensions below are the published AISC Shapes Database v15.0 values; the drawing is generated from them.
WT tees are W-shapes split at mid-depth — common truss chords and hangers, tabulated for the cut section.

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 WT6X68 the computed area is 0.93% from published and Ix 0.24%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Sx | 155,230 mm³ |
| Elastic modulus, Sy | 525,526 mm³ |
| Plastic modulus, Zx | 310,405 mm³ |
| Plastic modulus, Zy | 801,364 mm³ |
| Radius of gyration, rx | 40.6 mm |
| Radius of gyration, ry | 80.5 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
