Structural Tee (from M) · AISC Shapes Database v15.0 · United States
MT5X4.5 is a structural tee cut from an M-shape 127.0 mm deep with a 68.3 mm wide flange, weighing 6.7 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 MT5X4.5 the computed area agrees with the published value to 0.01% and Ix to 0.19%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Sx | 16,377 mm³ |
| Elastic modulus, Sy | 4,094 mm³ |
| Plastic modulus, Zx | 29,689 mm³ |
| Plastic modulus, Zy | 6,639 mm³ |
| Radius of gyration, rx | 41.1 mm |
| Radius of gyration, ry | 12.8 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
