The FL 89×1500×3.5 mm ground screw is the most powerful flanged model: Ø89 mm body, larger spiral and S355 steel for structures where bearing capacity is decisive – one- and two-storey prefab houses, steel halls and frames. The Ø180 × 8 mm flange with multiple slots accepts a wide range of posts and beams.
Key benefits
- Ø89 mm body, 3.5 mm wall, S355 steel
- Highest bearing capacity in the flanged range
- Ø180 × 8 mm flange with multiple mounting slots
- Hot-dip galvanised to EN ISO 1461 – long-lasting corrosion protection
- No digging, no concrete – can be loaded right after installation
- Does not disturb soil or roots; removable and reusable

Applications
- One- and two-storey prefab houses
- Bungalows and modular buildings
- Garages, canopies and halls
- Platforms, walkways and terraces
- Steel and timber structures
Installation
Installed by machine – with a hydraulic or electric ground screw driver. Spacing is defined by the structural design; for most structures it is between 1.5 and 3.0 m.
Why a ground screw instead of concrete?
A ground screw is a ready foundation in minutes: no excavation, no formwork, no concrete and no curing time. It leaves no construction waste, works even with a high water table, and can be unscrewed and relocated if needed – saving time, labour and often a significant part of the foundation cost.
