Structural Tee (from M) · AISC Shapes Database v15.0 · United States
MT3X2.2 is a structural tee cut from an M-shape 76.2 mm deep with a 46.7 mm wide flange, weighing 3.3 kg/m. The dimensions below are the published AISC Shapes Database v15.0 values; the drawing is generated from them.
MT tees are cut from M-shapes — light tees for small trusses and frames.

Derived section properties
Integrated from the section's own outline including the root and toe radii, whose arcs are integrated analytically rather than approximated by facets. For MT3X2.2 the computed area agrees with the published value to 0.01% and Ix to 0.07%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Sx | 4,382 mm³ |
| Elastic modulus, Sy | 1,588 mm³ |
| Plastic modulus, Zx | 7,929 mm³ |
| Plastic modulus, Zy | 2,536 mm³ |
| Radius of gyration, rx | 24.0 mm |
| Radius of gyration, ry | 9.4 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
