From designation to geometry
Reading the MT3X2.2 record
The MT designation identifies a tee depth series and nominal weight per foot. Use its own tabulated depth d = 3 in and flange width bf = 1.84 in rather than halving every dimension of another member.
This tee has web or stem thickness tw = 0.114 in, flange thickness tf = 0.171 in and centroid distance y = 0.841 in. Stem and flange orientation matter when matching the table's axes to a model.
Ix = 0.579 in⁴ and Iy = 0.09 in⁴ refer to the database x- and y-axes. Here Ix 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 MT3X2.2
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 × 2.2 lb/ft | 44 lb | 19.958 kg |
| 3 pieces | 3 × 44 lb | 132 lb | 59.874 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
MT3X2.2 alongside nearby MT records
These records share the same nominal series, outside envelope or leg arrangement, depending on the 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) |
|---|---|---|---|---|---|
| MT3X2.2 (this record) | 2.2 | 3 | 0.647 | 0.579 | 0.09 |
| MT3X1.85 | 1.85 | 2.96 | 0.545 | 0.483 | 0.086 |
Relative to MT3X2.2, MT3X1.85 changes nominal weight by -0.35 lb/ft, listed depth by -0.04 in, and area by -0.102 in². At the same hypothetical 20 ft length, the nominal weight difference is -7 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.
