Ground screw post anchors are helical foundation systems that screw directly into the ground, eliminating traditional concrete foundations. Engineered to handle loads in both tension and compression, they provide stable support for outdoor structures with minimal environmental disruption. These anchors enable quick installation without digging or curing time, allowing immediate construction after placement.
Manufactured from high-grade steel such as Q235 or S355, the anchors are hot-dip galvanized according to DIN EN ISO 1461 standards with coating thickness exceeding 80 microns for corrosion resistance. Available in lengths from 22 to 98 inches and diameters from 1.6 to 3.5 inches, they are tailored to specific load requirements. Models include adapter screws with mounting plates, pipe screws for steel tubes, post screws with U-profiles, and beam screws for joists, each designed for pressure resistance up to 12,364 lbs and lateral loads up to 4,300 lbs.
Applications span solar panel arrays, fencing, decking, carports, signage, and temporary structures. The anchors excel in uneven terrain, sandy soils, and environmentally sensitive areas requiring minimal ground disturbance. Installation uses hydraulic drivers or handheld tools to screw anchors into the ground with high torque, typically taking minutes per screw with little noise or vibration. The system is ready for immediate use after installation.
Products carry CE marking and ISO 9001 compliance, meeting standards such as ICC-ES ESR-4226. Special attachments including beam brackets, plates, and L-supports enhance functionality for tailored fitting and precise height adjustment in challenging conditions.
