From the basic to the most elaborate, a complete product range with a long service life.

A screw-in anchor consists of a shaft and a helix. When force is exerted on the anchor, the ground above the helix becomes compact providing tensile resistance (extraction cone theory). The anchor is made of highly resistant material.

  • The disc is designed with excellent rigidity and easy screw-in penetration.
  • Depending on the model, the screw tightening torque is imposed on either the shaft or on the disc.
  • The anchor's upper part is a function of the applied and imposed extraction forces.

Avantages

  • Corrosion resistant thanks to galvanising and sacrificial material thickness.
  • Immediate resistance.
  • Saves time.
