Technical specifications: • Total length: 2500 mm • Pipe diameter: 76 mm • Wall thickness: 3–4 mm • Number of spirals: 1–3 (depending on model) • Spiral diameter: 96–300 mm • Spiral type: Continuous / Helix • Extension type: P4 / R20 • Steel type: S235 / S355 • Coating: Galvanized ≥ 70 microns / Epoxy Load data (based on semi-rigid soil): • Compression load: 9000 kg • Pullout load: 6900 kg • Horizontal load: 1500 kg Coil type: Continuous coil – continuous threading along the length of the pipe, which transfers load through friction with the soil. Helix coil – flat plates to create a grip in the soil depth, effective for vertical loads. Installation method: Can be inserted using hydraulically powered equipment (such as Digga MM14K). Recommended uses: • Pergolas • Special installations - generators, military equipment, bridges, etc. • Heavy fences • Light structures • Infrastructure in complex terrain
The RB89×2500×4×3H300 ground screw is one of the strongest and most rugged models in the RockBase series.
Three 300 mm diameter Helix plates provide superior grip, suitable for extremely soft soils or for cases where anchoring with an extremely high load is required - up to 9 tons of pressure.
The pipe has a diameter of 89 mm, a thickness of 4 mm, is made of S235 steel and is coated with high-quality hot-dip galvanization.
A length of 2.5 m allows for particularly deep penetration and support on stable soil layers.
This screw is chosen for solar infrastructure projects, large wooden houses, steel foundations and cast slabs.
A powerful solution for those seeking engineering peace of mind even in challenging conditions.
