Technical specifications: • Total length: 2000 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: 4800 kg • Pullout load: 3500 kg • Horizontal load: 1000 kg Coil type: Continuous coil – continuous threading along the length of the pipe, which transfers the load through friction with the soil. Helix coil – flat plates to create a grip in the soil depth, effective for vertical loads. Method Installation: Can be inserted using hydraulically powered drilling equipment (such as Digga MM14K), or using a portable planetary electric screwing rig – especially for sites without access to heavy equipment. Recommended uses: • Pergolas • Decks • Fences • Light structures • Infrastructure in complex terrain • Solar parking lots • Mobile structure • Public decks • Glamping • Gates and fences
RockBase series 76mm diameter ground screws
constitute the core of solutions for rapid construction,
Accurate and clean in small-medium projects.
They come in a variety of lengths (1500–2000 mm),
With a continuous coil structure that provides maximum friction along the length of the tube
and ensures high resistance to both vertical and horizontal loads.
Made of S235 carbon steel, with a wall thickness of 3 mm,
With a galvanized coating ≥70μm – adapted for use in outdoor areas, in varying climatic conditions and on diverse soils:
Fill, sand, alluvial soil and gravel.
Thanks to quick installation with electric or hydraulic equipment, these screws are perfect for decks, pergolas, fences, temporary structures, light infrastructure, and more.
