The Unshakable Foundation: HDG Steel Ground Screw Piles
Build on a foundation of unwavering strength and durability with Longsun Green HDG Steel Ground Screw Piles. Our screw piles represent the modern standard for rapid, reliable, and robust structural support. Designed with a helical steel plate welded to a central shaft, they are mechanically screwed into the ground, creating an immediate, load-ready foundation for solar farms, residential decks, signage, and a multitude of other structures.
The key to their exceptional performance lies in the hot-dip galvanizing process. After fabrication, each pile is immersed in a bath of molten zinc, creating a metallurgical bond that provides a superior, long-lasting barrier against corrosion. By combining this unparalleled corrosion protection with a clean, vibration-free installation process, we offer a foundation solution that saves time, reduces costs, and is built to stand the test of time.

Key Features
Material & Coating: Fabricated from high-strength carbon steel. Features a hot-dip galvanized coating conforming to ISO 9001, with a standard coating thickness of 80µm (microns), providing a corrosion resistance of over 30 years in most soil conditions.
Shaft & Helix Design: Available in a range of shaft diameters (common sizes: 76mm, 89mm, 114mm) with varying wall thicknesses. Helix diameters typically range from 150mm to 350mm, with single, double, or triple helix configurations to optimize bearing capacity in different soils.
Load Capacity: Engineered for high axial (compressive and tensile) and lateral load resistance. Certified ultimate capacities often range from 50 kN to over 200 kN per pile, with designs customizable based on geotechnical surveys.
Installation & Quality Control: Installation torque is directly monitored and correlated to the pile's ultimate load capacity, providing real-time, verifiable proof of performance and eliminating guesswork.
Head Attachments: Equipped with a universal, hot-dip galvanized head and bolted attachment system for seamless integration with various solar mounting structures, timber beams, and steel columns.
Dimensions: Standard lengths from 1.0 meter to 3.5 meters, with couplers available for deeper installations to reach stable load-bearing strata.

Everything You Need to Know
Q: Why is hot-dip galvanizing better than a painted or electroplated coating?
A: Hot-dip galvanizing is a far more robust process. It creates a thicker, metallurgically bonded coating that is integral to the steel, unlike a painted layer that can be chipped or an electroplated coating that is thin and prone to damage. It offers superior protection against mechanical damage during installation and long-term abrasion from the soil.
Q: Are these piles suitable for all soil types?
A: They are highly versatile and perform excellently in a wide range of soils, including sand, clay, silt, and fill. They are particularly advantageous in areas with a high water table or expansive soils. Solid, un-fractured bedrock can be a challenge, though pre-drilling or specialized rock points can often provide a solution.
Q: Can I install them myself for a small project?
A: For very small projects like a garden shed or light-duty deck, handheld installation equipment can be used. For any structural or commercial application, we strongly recommend using trained installers with certified hydraulic equipment. This ensures correct torque is achieved, verifying the pile's load capacity and guaranteeing safety.
Q: What is the payback period?
A: Typically 5-8 years, depending on local solar irradiance, electricity rates, and government incentives.
