Product Overview
The multi-helix ground screw pile stacks 2-4 helix blades along the shaft to spread load through weak strata. In sand, fill and soft clay it doubles the pull-out capacity of a single-helix screw of the same length.
Blade pitch and diameter are selected per your geotech report; all blades are robotic-welded and hot-dip galvanized after fabrication for a void-free coating.
Key Features
- 2-4 helix blades — 2× pull-out in weak soils
- Robotic-welded blades — consistent penetration geometry
- HDG after welding — void-free galvanizing
- Geotech-matched design — blades sized to your soil report
- Ø76-114 mm shafts — load range up to 40 kN
- Compression + tension — handles uplift and downforce
Application Scenarios
Chosen for difficult ground:
- Sandy coastal plains — blades bite loose strata
- Fill and reclaimed land — load transfer to firm layers
- Soft clay regions — multi-level load spreading
- High-uplift sites — storm-zone solar farms
Configuration Options
- Helix count — 2 / 3 / 4 blades
- Blade diameter — 150-250 mm
- Shaft — Ø76 / Ø89 / Ø114 mm
- Length — 1600-3000 mm
- Top — flange or nut connection
