HP14x102 HP14x117 Structural Steel H-Piles
HP14×102 and HP14×117 beam steels belong to the American standard H-Pile. The "HP14" in the name means that the nominal depth of the section is about 14 inches, and the number (such as 102) represents the weight per foot (unit: pounds/foot). Unlike wide flange beams (W-type), HP steel has a flange width close to the section depth and is designed for pile foundation projects.

HP14×102 HP14×117 H-pile structural beam Size characteristics
1. The flange width and section depth of HP steel are close (bf≈d), and the web and flange thickness are the same, which optimizes the axial load-bearing capacity and resistance to lateral forces.
2. HP14×117 is thicker than HP14×102, with a larger cross-sectional area and moment of inertia, suitable for higher load-bearing requirements.
3. The moment of inertia (Ix and Iy) is relatively balanced, suitable for multi-directional forces.
4. Common lengths are 6 meters, 12 meters or customized on demand, and can be spliced to tens of meters in pile foundation projects.
Features of HP14×102 and HP14×117 H-type pile steel
High axial bearing capacity: The thickness of the flange and web is similar, and the cross-section is optimized to withstand vertical pressure, suitable for deep foundations.
Strong resistance to lateral forces: The wide flange and symmetrical cross-section provide good horizontal resistance to resist soil lateral pressure.
Corrosion resistance: A572GR50 and A992 materials are more durable in underground environments.
Construction flexibility: It can be quickly sunk into the soil by a pile driver and is easy to splice.
Recyclability: H-type pile steel can be pulled out and reused, which is environmentally friendly and economical.
