Our Heavy Duty Helical Ground Screw Ground Anchor is a professional foundation solution meticulously designed for both residential and commercial solar mounting systems, engineered to deliver exceptional stability, durability, and efficiency in diverse installation scenarios. Crafted from high-quality hot-dipped galvanized carbon steel (Q235 or Q355 grade) compliant with international standards (ISO 1461, ASTM A153), this ground anchor features a robust helical blade structure that ensures deep soil penetration and superior load-bearing capacity, effectively securing solar panels, mounting frames, and related structures against harsh environmental factors such as strong winds (up to 130 mph, ASCE 7-22 standard), heavy rainfall, frost heave, and soil settlement.
The integrated helical design, with beveled 45-degree leading edges on the blades, allows for effortless rotation into various soil types—including loam, clay, sand, and even gravel-rich substrates—without the need for extensive excavation, concrete pouring, or long curing times, significantly reducing on-site construction time and labor costs. Available in customizable specifications (length: 50cm-3.5m, helix diameter: 10cm-30cm, thickness: 2.5mm-6.0mm), it seamlessly adapts to different project scales: from small residential rooftop or ground-mounted solar setups to large-scale commercial solar farms, utility-scale arrays, and carport solar installations, even in high water-table or undulating terrain areas.
Equipped with precision laser-etched depth markers and compatible with torque-controlled installation tools, the anchor ensures millimeter-level installation accuracy, while its triple-layer zinc-aluminum coating or hot-dipped galvanized finish provides long-term corrosion resistance, extending the service life to over 25 years—matching the lifecycle of solar panels and minimizing maintenance costs. With OEM/ODM services available, it can be tailored to specific project requirements, making it a reliable, cost-effective, and eco-friendly alternative to traditional concrete foundations, ideal for professionals seeking efficient, sustainable solar foundation solutions.

Manufacturing Process
Step 1: Cutting
The length of welded pipe is 6 meters andthe welded pipe need to be cut by sawingmachine according to customer's need.
Step 2: Heating
Putting ground screw to high frequencyheating machine and make ground screwbe soft so that ground scew can beshaping.
Step 3: Shrinking
Using shrinkage machine to change theshape and diameter of ground screw.
Step 4: Punching
Using punching machine to do a hole orother for ground screw.
Step 5: Welding
The spiral blade of ground screw will bewelded by automatic welding machine.
Step 6: Galvanizing
The surface treatment is acid picking andhot dip galvanizing.
