11.11mm 7‑Wire Low‑Relaxation Bonded PC Strand | Structural Engineering Grade

Engineering‑Grade Structural Integrity. Manufactured for high‑load post‑tensioned and pre‑tensioned applications, our 11.11mm 7‑wire bonded prestressed concrete steel strand delivers uncompromising tensile performance, strict metallurgical tolerances, and certified compliance with global infrastructure standards.

1. Technical Specifications & Metallurgical Data

Designed for critical load paths and high‑stress environments. Every coil is engineered to meet strict international mechanical standards.

2. Core Engineering Advantages

• Optimized Low‑Relaxation Performance: Advanced thermal‑mechanical stabilization reduces initial stress loss, guaranteeing long‑term structural prestress retention over design life cycles.
• Superior Mechanical Interlock: The precise helical geometry of the 7‑wire layout maximizes shear bond strength between the steel tendon and structural grout/concrete.
