Foundation Pile

‌Material & Process‌
The product is made of high-quality hot-rolled steel (Q235B/Q355B, etc.) as the base material, treated with hot-dip galvanizing for corrosion resistance. The zinc coating thickness is ≥85μm, complying with the GB/T 13912-2020 standard. It can withstand harsh environments such as coastal areas, saline-alkali lands, and regions with frequent acid rain, effectively preventing rust and extending service life.
Precision cold bending/welding forming processes are used, resulting in uniform pile wall thickness (6mm-12mm, optional). The structure has high strength, with no defects such as sand holes or cracks. Dimensional tolerances are precise (±0.5mm), suitable for various photovoltaic bracket installation requirements.

‌Structural Design‌
A flange plate integrated molding design is adopted, with a flange plate thickness of ≥10mm. Multiple sets of embedded bolt holes (4/6/8 holes, conventional) are provided, ensuring tight fitting with foundations/brackets during installation, uniform force distribution, and significantly improved connection stability.
Segmented threaded/coupling design (optional) for the pile body allows on-site splicing and lengthening, adapting to different geological conditions (e.g., clay, sandy soil, rock layers) and burial depths (1.5m-4m, conventional). Some models come with reinforcement ribs, enhancing wind and snow load resistance (capable of withstanding ≥12-level wind and ≥50cm snow load).
Available with pointed or flat pile tips. The pointed tip facilitates screw-in construction, reducing pile driving resistance. The flat tip is suitable for impact or static pressure construction, meeting different construction process requirements.

‌Specification Diversity‌
Diameter range: Φ89mm-Φ273mm (mainstream Φ114mm/Φ140mm/Φ165mm). Length is customizable (1m-6m). Non-standard customization of dimensions, flange plate styles, and thread specifications is supported according to project requirements.

‌Core Advantages‌

1. ‌Durability & Low Maintenance Cost‌
   The hot-dip galvanized corrosion-resistant layer has strong adhesion and is not prone to peeling. The outdoor service life can exceed 25 years, far surpassing ordinary painted or cold-galvanized products. Minimal maintenance is required later, significantly reducing the overall operation and maintenance costs of photovoltaic power stations.

2. ‌Efficient Construction & Wide Adaptability‌
   Various construction methods such as rotary drilling, impact, and static pressure can be used. Large-scale excavation of foundation pits is not required. The construction cycle is more than 60% shorter than that of concrete foundation piles, reducing land damage and complying with environmental requirements. It is suitable for various installation scenarios such as mountains, slopes, tidal flats, and rooftops.
   Lightweight design (single pile weight ≤200kg) facilitates transportation and lifting, reducing construction labor and equipment costs. Standardized interfaces quickly connect with photovoltaic brackets, improving installation efficiency by 50%.

3. ‌Structural Stability & Safety‌
   Third-party mechanical testing confirms that bending, torsional, and compressive performance meet standards. It can withstand the impact of extreme weather (typhoons, blizzards) on photovoltaic brackets, ensuring the structural safety of power stations.
   The flange plate and pile body are fully welded and molded. Welding strength is ≥base material strength, with no welding defects, avoiding safety hazards caused by connection loosening during long-term use.

4. ‌Cost-Effectiveness & Environmental Friendliness‌
   Steel is recyclable, aligning with the green and low-carbon development concept of the photovoltaic industry. Under batch production, costs are controllable. Compared to concrete foundation piles, comprehensive costs are reduced by 15%-20%. Construction generates no construction waste, reducing environmental burden.
   Factory-standardized mass production ensures stable and controllable quality. The supply cycle is short (7-15 days for conventional orders), meeting the rapid construction needs of photovoltaic power stations.
