Galvanized Solar Helical Earth Anchors 73-114mm Shaft with 8-14in Helix Plates for Foundation Systems
Galvanized solar helical earth anchors, also known as screw piles or helical piers, are engineered deep foundation solutions designed for securing new foundations or repairing existing structures. These modern alternatives to traditional concrete footings feature steel shafts with welded helical plates that screw into the ground for superior stability.
- Modular 2m sections with galvanized steel construction
- Lead sections feature three progressively sized helices (8/10/12/14 inches)
- Extendable design with follower sections for additional depth
- Available in round or square shaft configurations
- Customizable steel grades and specifications
- Designed for both compression and tensile loads

- Residential and commercial building foundations
Screw piles are installed using rotary hydraulic equipment ranging from skid-steer loaders to 80-tonne excavators. Installation requires torque capacities from 5,000 Nm to 500,000 Nm depending on soil conditions and load requirements.
- 50% faster installation than traditional concrete foundations
- All-weather construction capability
- Minimal environmental impact and site disturbance
- Cost-effective alternative to excavation methods
- Immediate load capacity testing during installation
- Reduced carbon footprint compared to concrete
Our manufacturing process includes comprehensive quality testing of steel grade, welding integrity, galvanizing quality, and actual load testing to ensure 3-year shelf life and reliable performance.
