1. Short Introduction

Helical ground screw piles serve as an eco-friendly alternative to traditional concrete foundations. Widely adopted in ground-mounted solar power plants, these galvanized steel screw anchors can be installed rapidly without concrete pouring. Multiple blade designs are available to adapt to different soil conditions, perfectly matching all kinds of solar panel support structures.
