From designation to geometry
Reading the HP10X42 record
The 10 in depth series in HP10X42 is a designation. The tabulated depth d is 9.7 in and flange width bf is 10.1 in. The separately listed detailing depth ddet is 9.75 in.
The web thickness tw is 0.415 in and flange thickness tf is 0.42 in. Keep the exact designation with these dimensions: matching the depth series does not guarantee matching flanges, web geometry or connection fit.
Ix = 210 in⁴ and Iy = 71.7 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 HP10X42
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 × 42 lb/ft | 840 lb | 381.018 kg |
| 3 pieces | 3 × 840 lb | 2,520 lb | 1,143.053 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 bearing pile shape?
An HP-shape is a hot-rolled bearing-pile section proportioned for driven foundation service. Its geometry is intended to perform as a pile and differs from ordinary building-column selection even when the cross-section looks similar to a wide-flange shape.

Compare published reference values
HP10X42 alongside nearby HP 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) |
|---|---|---|---|---|---|
| HP10X42 (this record) | 42 | 9.7 | 12.4 | 210 | 71.7 |
| HP10X57 | 57 | 9.99 | 16.7 | 294 | 101 |
Relative to HP10X42, HP10X57 changes nominal weight by +15 lb/ft, listed depth by +0.29 in, and area by +4.3 in². At the same hypothetical 20 ft length, the nominal weight difference is +300 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.
