Product Overview
The ground screw anchor is a steel pile with a welded helix that screws into the soil to become an instant foundation. Hot-dip galvanized Q235B shafts of Ø76 mm reach 1000-3000 mm deep and carry flanges or nuts on top for any connection detail.
Installation takes 2-4 minutes per screw with a rotary drive head — no concrete, no curing, no spoil. Load capacity is verified on site with pull tests; typical pull-out in medium soil exceeds 25 kN.
