Why Die-Formed
Outperforms
Spin-Twisted
Competitors typically "spin twist" their helical bars — a manufacturing process that can create an inconsistent pitch, introduces internal stresses, and often produces unreliable performance characteristics. Thor Helical's patented die-formed process is fundamentally different.
Consistent Pitch
Die-formed manufacturing controls pitch precisely along the full bar length. Consistent pitch = uniform load distribution and maximum anchoring performance.
Stronger Core
Die-forming reduces internal stresses, preventing weak points. Spin-twisted bars carry these stress points throughout their length creating potential failure points.
Superior Quality Control
Our patented process gives complete control over the finished tie. Variable spin-twisted products can result in inconsistent finishes and risks unreliable performance.
Greater Cross-Sectional Strength
Thor Helical bars provide greater strength over their cross-sectional area compared to all other helical tie products on the market.
Uniform pitch = predictable, certified performance
Variable pitch = unreliable anchoring, substrate damage
