Bearing Pile · AISC Shapes Database v15.0 · United States
HP12X53 is a bearing pile 299.7 mm deep with a 304.8 mm wide flange, weighing 78.9 kg/m. The dimensions below are the published AISC Shapes Database v15.0 values; the drawing is generated from them.
HP bearing piles keep flange and web at the same thickness for driving; the near-square profile takes soil abrasion and hard driving on both faces.

Derived section properties
Integrated from the section's own outline including the root and toe radii, whose arcs are integrated analytically rather than approximated by facets. For HP12X53 the computed area agrees with the published value to better than 0.01% and Ix to 0.07%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Sx | 1,092,309 mm³ |
| Elastic modulus, Sy | 342,510 mm³ |
| Plastic modulus, Zx | 1,211,674 mm³ |
| Plastic modulus, Zy | 523,505 mm³ |
| Radius of gyration, rx | 127.9 mm |
| Radius of gyration, ry | 72.3 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
