Greenhouse trellis anchor

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.
