From designation to geometry
Reading the W33X241 record
The 33 in depth series in W33X241 is a designation. The tabulated depth d is 34.2 in and flange width bf is 15.9 in. The separately listed detailing depth ddet is 34.125 in.
The web thickness tw is 0.83 in and flange thickness tf is 1.4 in. Keep the exact designation with these dimensions: matching the depth series does not guarantee matching flanges, web geometry or connection fit.
Ix = 14,200 in⁴ and Iy = 933 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 W33X241
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 × 241 lb/ft | 4,820 lb | 2,186.315 kg |
| 3 pieces | 3 × 4,820 lb | 14,460 lb | 6,558.946 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 wide-flange shape?
A W-shape is a hot-rolled, doubly symmetric wide-flange section commonly used for beams and columns. Its relatively wide flanges and web distribute material efficiently for many bending and axial-force applications.

Compare published reference values
W33X241 alongside nearby W 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) |
|---|---|---|---|---|---|
| W33X241 (this record) | 241 | 34.2 | 71.1 | 14,200 | 933 |
| W33X221 | 221 | 33.9 | 65.3 | 12,900 | 840 |
| W33X263 | 263 | 34.5 | 77.4 | 15,900 | 1,040 |
Relative to W33X241, W33X221 changes nominal weight by -20 lb/ft, listed depth by -0.3 in, and area by -5.8 in². At the same hypothetical 20 ft length, the nominal weight difference is -400 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.
