Products Description
Efficient Screw Piles for Solar Projects
Efficient Screw Piles (Helical Piles) are high-strength steel foundations featuring helical plates. They are mechanically twisted into the ground using hydraulic equipment to provide a stable, immediate-support base for various solar mounting systems, eliminating the need for excavation and concrete.

Product Core Features
Rapid, Non-Excavation Installation
Installation requires only compact machinery, with no digging or earth removal. This significantly accelerates project timelines, reduces labor costs, and minimizes overall site disruption.
Immediate Load-Bearing Capacity
Unlike concrete foundations requiring weeks to cure, screw piles are ready to bear design loads immediately after installation. Solar racking assembly can commence right away.
Exceptional Durability & Corrosion Resistance
Manufactured from high-strength steel with a hot-dip galvanized coating (minimum 80μm), the piles offer long-term resistance to corrosion, ensuring reliable performance in harsh environments, including coastal areas.
Superior Geotechnical Adaptability
Installation depth and configuration can be adjusted in real-time based on torque readings. This ensures optimal stability and performance across various challenging soil conditions, including soft, rocky, or high-water-table sites.
High Structural Strength
Engineered for high compressive and tensile (pull-out) resistance, these piles provide a robust and stable foundation capable of withstanding extreme wind loads and freeze-thaw cycles.
Environmental Friendliness & Reusability
The installation process preserves the natural soil structure and causes minimal landscape disturbance. Additionally, piles can typically be unscrewed and reused or recycled at the end of the project life.
Key Points for Helical Pile Installation
Pre-Installation Preparation
Conduct a site survey to identify and avoid underground utilities and large obstructions.
Clear the work area and clearly mark all pile locations.
Three-Step Installation Process
Vertical Placement: Use a level to ensure perfect vertical alignment during initial installation.
Torque to Specification: Drive the pile until the target installation torque is reached-then stop immediately (Critical Step!).
Document Data: Record the final depth and installation torque for each pile.
Important Precautions
If refusal is met, do not force installation. Report the issue immediately.
Use a cold-cutting saw (abrasive saw) for any required pile trimming. Apply zinc-rich paint to any cut surfaces.
When attaching mounting structures, tighten bolts in a cross-pattern sequence.
Safety Checklist
Wear proper PPE: hard hat, safety gloves, and protective glasses.
Keep a safe distance from rotating machinery during operation.
Suspend all work during inclement weather (e.g., high winds, heavy rain, lightning).
Acceptance Criteria
Piles must be plumb without visible bending.
Pile tops must be leveled to a uniform elevation.
Submit the completed pile installation log for review.
Core Principles: Install Plumb, Achieve Design Torque, Maintain Complete Records.
