From designation to geometry
Reading the HSS10.750X0.375 record
The listed outside diameter OD is 10.8 in.
The designation carries a nominal wall thickness tnom of 0.375 in. This record lists design wall thickness tdes = 0.349 in, a 0.026 in difference. Keep the two fields separate when transferring data; do not infer a product specification or substitute a different HSS dataset from the name alone.
Ix = 154 in⁴ and Iy = 154 in⁴ refer to the database x- and y-axes. The two listed values are equal. 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 HSS10.750X0.375
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 × 41.59 lb/ft | 831.8 lb | 377.298 kg |
| 3 pieces | 3 × 831.8 lb | 2,495.4 lb | 1,131.894 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 hollow structural section?
An HSS is a closed structural tube with square, rectangular, or round outside geometry. Closed sections provide useful biaxial and torsional behavior and are often selected for columns, braces, trusses, exposed framing, and space-conscious conditions.

HSS10.750X0.375 alongside nearby HSS 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) | Outside diameter (in) | Area (in²) | Ix (in⁴) | Iy (in⁴) |
|---|---|---|---|---|---|
| HSS10.750X0.375 (this record) | 41.59 | 10.8 | 11.4 | 154 | 154 |
| HSS10.750X0.313 | 34.87 | 10.8 | 9.55 | 131 | 131 |
| HSS10.750X0.500 | 54.79 | 10.8 | 15 | 199 | 199 |
Relative to HSS10.750X0.375, HSS10.750X0.313 changes nominal weight by -6.72 lb/ft, listed outside diameter by 0 in, and area by -1.85 in². At the same hypothetical 20 ft length, the nominal weight difference is -134.4 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.
