High-Strength Smooth Bar
Smooth shank with rolled metric end threads for fine-adjustable prestressing.
The TS High-Strength Smooth Bar is a steel bar with a smooth shank and rolled metric end threads for post-tensioning and anchoring systems. Rolled threads formed by cold plastic deformation give high fatigue performance, while the fine thread pitch allows precise adjustment and reduced draw-in loss.
