Application description:

Widely used as foundation supports for solar power plants (ground-mounted PV systems), agricultural photovoltaic greenhouses, and commercial rooftop solar arrays. Also suitable for fence posts, sign foundations, and light-duty structural supports. The helical or driven design allows quick installation without concrete, reducing project time and cost. Hot-dip galvanized finish ensures long-term corrosion resistance in outdoor and ground-contact environments.

Production description

Steel coil is roll formed or welded into C, U, square or spiral shape, then cut to length. For screw piles, helical blades are welded onto the shaft. The pile is hot-dip galvanized (Z275–Z600) for corrosion protection. Finished piles are inspected for coating thickness, straightness, and tip sharpness before packing.

Shipping Packaging

For export, photovoltaic steel piles are bundled with wooden separators, secured with steel straps, fitted with end protectors (for threaded or pointed tips), and packed on ISPM-15 pallets. Labels include grade, type, length, quantity, and heat number for safe sea freight.

FAQ

1. How to store photovoltaic steel piles to prevent coating damage and rust?

Store on level, dry ground on wooden sleepers or pallets, keep piles elevated to avoid moisture contact. Do not drop or drag piles to prevent galvanized coating scratches. For long-term storage, keep original wrapping and store under cover. Minor coating damage should be repaired with zinc-rich paint before installation.

2. How are photovoltaic steel piles installed in the ground?

Most piles are installed by direct driving using hydraulic pile drivers or rotary drilling (for helical piles). Spiral piles are screwed into the ground, while C/U piles are driven with impact hammers. No concrete foundation is required, allowing fast installation and immediate loading. Installation depth depends on soil conditions and design load.

3. What galvanized coating weight is recommended for different soil conditions?

Z275 (45µm) is suitable for normal soil with moderate corrosion risk. Z350–Z450 (60–75µm) is recommended for acidic, alkaline, or high-moisture soils. For coastal areas with high salt spray, Z550–Z600 (85–120µm) or additional epoxy/polyurethane top coating is preferred to ensure long-term service life (25+ years).
