Installation Process
Screw piles are wound into the ground using rotary hydraulic equipment with torque capacities ranging from 5,000 Nm to 500,000 Nm. Installation equipment includes skid-steer loaders, mini-excavators, backhoes, and 5-80 tonne excavators.
- Position the lead section with multiple helical bearing plates
- Rotate into ground to predetermined depth and torque specifications
- Add extension sections as needed for additional depth requirements
- Attach pile caps or brackets for foundation integration
- Immediate load testing capability after installation
Applications
- Solar photovoltaic support systems
- Timber-frame construction foundations
- Advertising and traffic signage structures
- Urban garden and landscape construction
- Telecommunication towers and flag poles
- Foundation repair and structural stabilization
Quality Assurance
Our manufacturing process includes comprehensive testing of steel quality, welding integrity, galvanizing standards, and actual field trials. Annual production capacity: 300,000 pieces with 3-year shelf life guarantee.
