Structural Tee (from W) · AISC Shapes Database v15.0 · United States
WT18X141 is a structural tee cut from a W-shape 472.4 mm deep with a 421.6 mm wide flange, weighing 209.8 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 WT18X141 the computed area is 0.88% from published and Ix 0.47%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Sx | 1,359,849 mm³ |
| Elastic modulus, Sy | 1,183,589 mm³ |
| Plastic modulus, Zx | 2,408,573 mm³ |
| Plastic modulus, Zy | 1,827,118 mm³ |
| Radius of gyration, rx | 136.9 mm |
| Radius of gyration, ry | 97.0 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
