High-Quality Helical Blades – Core of Screw Pile Performance

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.

Certified Welding Quality – Internationally Recognized

All welding follows ISO 9001 Quality System, with certifications including:

CWB (Canadian Welding Bureau) W47.1 Certification – Canada’s highest welding quality standard;

CE Certification – Compliance for EU markets.

CWB certification is recognized as equivalent to:

AWS D1.1 (United States);

oAS/NZS 1554 (Australia);

oEN ISO 3834 (European Union).

Our welding quality fully meets North American, European, and Australian standards.

Standard material: Q355B steel pipe & plate;

Optional material (per client request): Q235B steel pipe & plate;

Both materials are internationally equivalent and recognized.

Under Canadian engineering supervision, we combine strict material selection with proven OEM/Design-Assistant OEM capability to ensure top performance.

We provide OEM and Design-Assistant OEM services, tailoring screw piles to your project’s design requirements.
