High Performance:Manufactured from 17-4PH stainless steel with tensile strength exceeding 1030 MPa, offering outstanding corrosion resistance, fatigue performance, and low relaxation.
Long-Term Durability:Maintains stable prestress over time, enhancing structural capacity and lifetime safety.
Inherent Corrosion Protection:Corrosion resistance comes from the material itself, eliminating the need for grouting, grease, or other protective systems.
Lower Life-Cycle Cost:Reduced maintenance requirements make it ideal for marine, coastal, and chloride-rich environments.

Key Benefits
