Why Our Screw Piles Are Trusted Worldwide
High-Quality Helical Blades
Certified Welding Quality
Material Selection & Professional OEM Service
Our Commitment
- The helical blade is the heart of the screw pile. Only True Helix Blades ensure:
- Stable penetration at one pitch per revolution;
- Avoiding soil auguring or voids, ensuring true load capacity;
- Accurate weld positioning and consistent weld quality;
- We use rotational pressing technology to guarantee precise pitch, angle, and geometry, ensuring both installation efficiency and long-term design integrity.
- Backed by the guidance of Canadian professional engineers and more than 15 years of hands-on manufacturing experience, our screw pile production process has been refined into a world-class standard of quality.
- International research has proven that blade geometry directly determines pile performance—poorly formed blades significantly weaken both installation efficiency and ultimate capacity.
High-quality blades = High-quality screw piles.
