Galvanized Earth Ground Screw Anchor Solar Foundation Installation Helical Pile
The Galvanized Earth Ground Screw Anchor is a heavy-duty helical pile designed for solar foundation installation where deep, reliable embedment is essential. The larger 89 mm shaft and wide helix deliver the pull-out resistance needed for large arrays, carports and structures exposed to high wind uplift, while the galvanized finish protects the pile through decades of ground contact.
As an adjustable helical pile, this anchor can be driven to the required torque and then levelled with a cast flange plate, allowing framing to start immediately without concrete curing. The system suits slopes, rocky soils and cold climates, giving engineers a repeatable foundation that is quick to install, easy to test and simple to remove at end of life.
Key Features
- Heavy Duty Helical Pile: A robust 89 mm shaft and wide helix provide the uplift and compression capacity demanded by large solar arrays and carports.
- Solar Foundation Anchor: Purpose-built for photovoltaic foundations, the anchor keeps arrays plumb and level even on uneven or sloping ground.
- Galvanized Protection: Hot-dip galvanizing resists ground moisture, frost and soil chemistry, protecting the pile in wet and coastal conditions.
- Fast Torque-Based Install: Driving to a target torque gives measurable, verifiable capacity without excavated footings or concrete curing.
- Levelling Flange Plate: A cast flange allows quick height and angle adjustment so racking lines run straight across the whole project.
- Removable and Reusable: At end of life the pile unscrews with minimal ground disturbance, aiding site restoration and land reuse.

Applications
This galvanized helical pile is used for solar foundation installation on utility farms, carports, residential arrays and agrivoltaic projects. It also supports street lighting poles, signage, fences and timber structures where fast, concrete-free anchoring is preferred. Because the pile adapts to slopes and variable soils, it is a frequent choice for remote sites and projects with tight installation schedules.
Packaging & Quality Assurance
Every helical pile is shipped on a steel pallet with a fitted thread protector, protective film and export-grade strapping to keep the helix and thread in perfect condition. Under ISO 9001:2015 controls, each lot is inspected for weld quality, coating thickness and dimensional accuracy. Torque test records and material certificates are available to help buyers confirm load capacity before installation.
