From designation to geometry
Reading the MT2.5X9.45 record
The MT designation identifies a tee depth series and nominal weight per foot. Use its own tabulated depth d = 2.5 in and flange width bf = 5 in rather than halving every dimension of another member.
This tee has web or stem thickness tw = 0.316 in, flange thickness tf = 0.416 in and centroid distance y = 0.512 in. Stem and flange orientation matter when matching the table's axes to a model.
Ix = 1.05 in⁴ and Iy = 4.35 in⁴ refer to the database x- and y-axes. Here Iy is numerically larger. Axis letters are labels, not a guarantee that x is always the larger axis. These are geometric properties, not allowable loads or complete member capacities.
Match the axis and dimension conventions to the figures in the AISC v16.0 workbook Readme. The profile above simplifies manufacturing geometry; its outline is not used to recalculate the published properties.
Worked quantity example
Nominal weight for MT2.5X9.45
Assume 3 pieces, each 20 ft (6.096 m) long. This is a hypothetical quantity example, not a stock-length or lifting recommendation.
| Quantity | Calculation | Nominal pounds | Kilogram equivalent |
|---|---|---|---|
| One 20 ft piece | 20 ft × 9.45 lb/ft | 189 lb | 85.729 kg |
| 3 pieces | 3 × 189 lb | 567 lb | 257.187 kg |
Conversion: 1 lb = 0.45359237 kg; displayed results are rounded. This multiplication excludes connection plates, bolts, weld metal, coatings, cutting allowances and actual material variation. Use the material takeoff for your own lengths and quantities.
Shape family context
What is a structural tee cut from an M-shape?
An MT is a structural tee produced from a miscellaneous M-shape. It inherits geometry from the parent section and must be identified by its exact tee designation and listed properties.
Learn how shape properties workDetailing watch
Confirm parent-series geometry, stem and flange orientation, availability, connection eccentricity, and fabrication requirements instead of treating it as an interchangeable WT.

Compare published reference values
MT2.5X9.45 alongside nearby MT records
No other record shares this exact nominal series; these are the nearest weights in the same family. Peers are ordered by absolute weight difference, then listed depth and designation. The table does not rank structural performance or approve a substitution.
| Record | Weight (lb/ft) | Depth (in) | Area (in²) | Ix (in⁴) | Iy (in⁴) |
|---|---|---|---|---|---|
| MT2.5X9.45 (this record) | 9.45 | 2.5 | 2.78 | 1.05 | 4.35 |
| MT6.25X6.2 | 6.2 | 6.27 | 1.82 | 7.29 | 1 |
| MT6X5.9 | 5.9 | 6 | 1.74 | 6.61 | 0.543 |
Relative to MT2.5X9.45, MT6.25X6.2 changes nominal weight by -3.25 lb/ft, listed depth by +3.77 in, and area by -0.96 in². At the same hypothetical 20 ft length, the nominal weight difference is -65 lb.

Data is derived from the AISC Shapes Database v16.0, consistent with the AISC Steel Construction Manual, 16th Edition, 1st Printing. AISC advises professional verification before use in a specific application. The downloadable DXF is a nominal reference profile and may simplify rolled fillets, flange tapers, angle radii, HSS corner radii, and other manufacturing geometry. Verify all dimensions and suitability before design, detailing, ordering, or fabrication.
