Description
Technical Specifications
Our screw foundation piles are the industry standard for securing utility-scale solar arrays and heavy-duty infrastructure. Engineered as a high-performance alternative to concrete foundations, these ground screws provide an immediate load-bearing base that is both environmentally friendly and cost-effective. With a universal multi-hole flange design, these piles ensure seamless compatibility with a wide range of solar racking systems and structural supports.
Designed for rapid deployment, these screw foundation piles eliminate excavation and curing times, allowing your project to move directly from foundation setting to racking installation.

Key Features
High-Torque Spiral Design: The continuous spiral blade is engineered to cut through various soil densities, providing superior pull-out resistance and vertical stability.
Universal Multi-Hole Flange: The reinforced top flange features a versatile hole pattern, allowing for easy bolting and precise alignment of solar panel support structures.
Heavy-Duty Galvanized Steel: Manufactured from high-strength carbon steel with a hot-dip galvanized finish to ensure 25+ years of corrosion resistance in harsh environments.
Zero-Concrete Foundation: This sustainable solution requires no concrete pouring, significantly reducing site environmental impact and labor costs.
All-Weather Installation: Unlike concrete, these screw foundation piles can be installed in freezing temperatures or high-moisture conditions without affecting structural integrity.
Installation Workflow
Site Positioning: Mark the foundation points according to the racking layout.
Pile Driving: Use a hydraulic or electric ground screw driver to rotate the screw foundation piles into the soil until the flange reaches the desired height.
Racking Attachment: Bolt the solar support brackets directly to the universal flange for a secure, vibration-resistant connection.
FAQ
Q: Are these screw foundation piles suitable for rocky or extremely hard soil?
A: Yes. For dense or rocky soil, our screw foundation piles can be used in conjunction with a pre-drilling process. Once the pilot hole is prepared, the screw provides a high-friction, stable anchor that is ready for immediate loading.
Q: How do you guarantee the quality of the galvanization for long-term use?
A: We follow strict ISO 1461 standards for hot-dip galvanization. Every screw foundation pile undergoes a rigorous coating process to ensure a thickness that protects the steel from underground corrosion for over 25 years.
Q: Can these piles be removed and reused for temporary projects?
A: Absolutely. One of the major benefits of screw foundation piles is that they can be unscrewed from the ground without leaving debris behind, making them an ideal choice for both permanent utility farms and temporary event structures.
