✅ Product Features
Material & Craftsmanship: The main body is constructed from Q355B high-strength steel, featuring a comprehensive hot-dip galvanized finish (DIN EN ISO 1461) with a uniform and dense zinc coating. The helical blades are thickened and cold-rolled at the outer edges for enhanced reinforcement, ensuring superior resistance to deformation and wear.
Optimized Blade Structure: Features multiple widened helical blades (outer diameter ≥ 320mm) with a variable pitch design and a thickened root transition zone. This design minimizes soil penetration resistance and soil disturbance during installation, allowing for settlement control accuracy within ±3mm.
Flexible Customization: Available in a range of specifications: pile diameters from 76–114mm, wall thicknesses from 3–4mm, and lengths from 600–3000mm. Flange or bolted connections are available options, compatible with various types of PV mounting structures and installation tilt angles.
Rigorous Quality Control: Manufactured through standardized factory processes with batch-by-batch mechanical and anti-corrosion testing. Certified under CE and ISO 9001 standards, backed by a 10-year warranty and a 25-year service life.
✅ Core Functionality
High-Load Anchoring: Each individual pile offers high load-bearing capacity: ≥ 35kN in compression, ≥ 25kN in tension (uplift), and ≥ 50kN/m in lateral pressure. It effectively withstands extreme loads—such as strong winds, heavy snow accumulation, and freeze-thaw cycles—ensuring the long-term stability of the PV array.
Rapid Foundation Construction: Serves as a direct replacement for traditional cast-in-place concrete piles, requiring no curing time; installation of a single pile takes only a few minutes. This significantly shortens project timelines (saving up to 60% compared to traditional foundations) while reducing labor and equipment costs.
Geological Adaptability:As the helical blades rotate into the ground, they actively engage with the soil strata. This ensures uniform structural support across diverse terrains—including soft soil, reclaimed land, permafrost regions, mountainous areas, and hilly landscapes—thereby preventing differential settlement.
Eco-Friendly & Recyclable: Requires no earthworks or excavation, generates zero construction waste, and produces minimal vibration and noise during installation. At the end of a project's lifecycle, the piles can be reverse-rotated and extracted; over 90% of the pile material is reusable, allowing for the full restoration of the site to its original condition in alignment with green infrastructure principles.
✅ Application Scenarios
Ground-Mounted PV Power Plants: Ideal foundation solution for large-scale centralized PV farms, solar projects situated in mountainous or hilly regions, installations on tidal flats or saline-alkali soils, and projects located in permafrost zones. Compatible with a wide variety of mounting structures and PV module layouts. Distributed PV: Foundations for commercial and industrial rooftop systems (including complementary ground-mounted arrays), as well as "Agri-PV" and "Fishery-PV" projects—all designed to avoid disruption to arable land and local ecosystems.
Other New Energy Applications: Foundations for small-scale wind turbines, solar streetlights, surveillance camera poles, and energy storage equipment—providing stable and reliable geotechnical solutions.
Municipal and Agricultural Facilities: Foundations for fencing, billboards, landscape shelters, greenhouses, and small cabins—serving as an efficient and eco-friendly alternative to traditional concrete foundations.
