Continuous-thread hollow SDA rods manufactured in high-yield alloy steel. Designed for simultaneous drilling, flushing, and pressure grouting across complex fractured geological formations.
CTA & SDA Rods
CTA Rods (Composite Threaded Anchors)
CTA Rods manufactured from high-tensile structural alloy steel featuring full-length external rope threading for continuous coupling and custom on-site length adjustment.
CTA & SDA Rods
Fully Threaded Rods
High-tensile fully threaded steel rods engineered for heavy tieback anchorages, soil nailed slope walls, and structural micropiles.
ABOUT CTA & SDA Rods
