HP bearing piles (EN 10365, BS 4-1, ASTM A6)

Standard: EN 10365:2017 · BS 4-1 · ASTM A6/A6M · EN 10034 (tolerances)

HP sections are H-beams with web and flanges of almost equal thickness, made to be driven into the ground as bearing piles. Equal thicknesses stop the section buckling locally while it is driven and give the same corrosion allowance on every face.

Three series are listed: European (HP 220, HP 320…, by depth and mass), British (HP 305 × 305…, serial size and mass, formerly called UBP) and American in metric units (HP 310 × 310…, which are HP 12 sizes in the ASTM A6 inch designations).

Notes

Section properties are calculated for the nominal dimensions. Mass is for a density of 7.85 kg/dm³.
Piling grades are usually S355 to EN 10025-2, or ASTM A572 Grade 50 for the American series.
