Product Description
Ground Helical Piers for Deep Foundation Systems
Helical piers, also known as helical piles, screw piles, or screw anchors, are advanced foundation systems designed for stabilizing new constructions and repairing existing foundations. These galvanized steel components feature modular 2-meter sections with multiple helices for superior load distribution.
Key Product Features
- Fast installation with immediate load-bearing capacity
- Ideal for limited access sites and varied terrain
- Pre-engineered design with on-site modification capability
- Cost-effective alternative to auger cast piles and drilled shafts
- Installation in any weather condition with minimal site disturbance
- Deep foundation support for increased bearing capacity

All sizes and steel grades are customizable to meet specific project requirements.
Performance Benefits
Helical piers transfer structural loads deep into stable subsoils, providing exceptional compression, lateral, and uplift support. Installation rates typically range from 6-10 RPM, achieving depths of approximately 0.6 meters per minute.
Application Areas
- Transmission tower foundations and utility applications
- Photovoltaic support systems and wind energy projects
- Residential and commercial foundation repair
- Retaining walls and marine structures
- Industrial construction and infrastructure projects
Environmental Advantages
Helical piles minimize environmental impact with no concrete curing required, reduced excavation, and the ability for removal and reuse.
Manufacturing Capabilities
Annual production capacity of 300,000 pieces with comprehensive quality control including steel grade verification, welding quality, galvanizing quality, and load testing.
