Product Description
Steel Portable Foundation Ground Screw for Solar Mounting Systems
Helical piers, also known as anchors, piles or screw piles, are deep foundation solutions used to secure new or repair existing foundations. This modern alternative to traditional cement footings features engineered steel posts with screw-like helices for superior performance.
Product Overview
Each pier consists of a central steel shaft with helical engineered metallic plates attached. The steel plate thickness, diameter, number of helices, and operational parameters are determined by design life requirements, environmental corrosion factors, geotechnical conditions, and structural load demands.

Technical Advantages
Performance Benefits
- High load capacity with excellent stability
- Superior settlement resistance and pull-out strength
- Soil load bearing capacity tested during installation
- Available with single, double, and triple helix blades
Installation & Operation
Screw piles are wound into the ground using various earthmoving equipment fitted with rotary hydraulic attachments. Machinery ranges from skid-steer loaders to 80 tonne excavators with torque capacities from 5,000 Nm to 500,000 Nm. Correct installation techniques ensure engineered design load and settlement outcomes.
