Product Description
With superior patented inertia welding technology, we provide the strongest helical piles for soil stabilization and foundation repair solutions.
Product Overview
Helical piers, also known as anchors, piles or screw piles, are deep foundation solutions used to secure new or repair existing foundations. This modern improvement to traditional cement footings consists of engineered steel posts with screw-like helices that provide superior load-bearing capacity.
Technical Specifications
Screw piles are provided in modular sections approximately 2m long. The lead section typically has three galvanized steel helices of increasing size welded to the shaft. For additional depth requirements, 2m follower sections are available. Galvanized steel pile caps are also provided.

Key Advantages
Structural Performance
Spiral ground piles are driven underground in a revolving manner, minimizing soil disturbance while maximizing soil utilization. The blade structure provides excellent tensile pull-out force and insertion grip.
Installation Efficiency
As a modern foundation technology, spiral ground piles offer convenient construction, short project timelines, minimal environmental impact, and easy migration and recycling capabilities.
Cost Effectiveness
Compared to traditional concrete foundations requiring formwork, rebar, pouring, curing, and backfilling, spiral ground piles only require positioning and driving, significantly reducing material and labor costs.
All-Weather Construction
Minimal environmental impact allows construction under most climatic conditions, including rain, snow, and freezing weather.
Applications
Photovoltaic screw ground piles reduce foundation costs for support systems, shorten installation time, and minimize environmental impact. This cost-effective solution is applicable to solar photovoltaic, wind energy, and construction industries, offering high load performance, stability, settlement resistance, and pull-out resistance.
Installation Equipment Compatibility
- Hand-held equipment
- Mini-excavators and skid steers
- Backhoes and trackhoes
- Crane-supported rigs
This versatility, combined with the ability to immediately load and test anchors, makes helical piles a convenient and economical solution for concrete stabilization and foundation repair projects.
Manufacturing Capabilities
Annual production capacity: 300,000 pieces with comprehensive quality testing including steel grade, welding quality, galvanizing quality, and actual trial testing.
