Introduction to Ground Screw Piles
Ground screw piles are an efficient, innovative foundation solution composed of hot-forged steel pipe bodies, precision-welded spiral blades and connecting flanges. All finished piles are fully hot-dip galvanized after welding to ensure excellent corrosion resistance and long-term durability.
Working like wood screws, these steel piles are screwed into the ground by professional rotary equipment. Replacing traditional concrete foundations, they allow immediate load bearing after installation with no concrete curing time, greatly boosting construction efficiency.
Compared with traditional wet construction, ground screw piles feature better site adaptability and faster installation. They save costs on ground leveling, excavation and soil disposal, making them widely used in solar farms, ground-mounted PV systems and photovoltaic carports.
Core Working Principle
Fitted with one or more helical blades, the pile is rotated into soil via mechanical torque during installation. It forms a stable structural anchor that bears both vertical and horizontal loads. As a superior alternative to concrete pouring foundations, it enables more flexible and faster construction.
Key Structural Advantages of Ground Screw Piles
The rotary installation method disturbs the original soil minimally and preserves the site’s natural load-bearing capacity, unlike conventional excavation and piling methods.
The optimized spiral blade design delivers outstanding pull-out resistance and firm soil grip. It fits various soil types, disperses loads evenly and prevents foundation displacement and settlement, guaranteeing stable and safe support for above-ground
