Multi-Strand Anchorage Systems High-Performance Post-Tensioning Solutions

Key Features & Advantages

​Engineered to meet international construction standards (such as fib, PTI, and ETAG), our systems offer distinct advantages for structural engineers and contractors:

· â€‹High Load Capacity: Designed to securely lock and transfer high forces from multiple prestressing strands (typically ranging from 2 to 55 strands or more) into the concrete structure.

· â€‹Optimal Wedge Design: Features precisely heat-treated, multi-piece wedges that ensure uniform grip on the steel strand without causing premature fatigue or notching.

· â€‹Corrosion Protection Options: Available in standard, encapsulated, and fully greased/waxed configurations with heavy-duty plastic caps for aggressive environments (marine structures, bridges).

· â€‹Reliable Power Transfer: The heavy-duty bearing plates distribute concentrated forces evenly across the concrete cross-section, minimizing local stress concentrations.

· â€‹Easy Installation & Stressing: Compatible with standard hydraulic stressing jacks and wedge-seating equipment, ensuring smooth on-site tensioning operations.

Primary Applications of Our Multi-Strand Anchorage Systems

Our prestressed multi-strand anchorage systems are heavy-duty, versatile solutions trusted by structural engineers and contractors worldwide. They are widely applied in various civil engineering, infrastructure, and heavy construction sectors:

 Bridge & Highway Infrastructure

· Segmental Bridges: Securing precast concrete segments in high-speed rail and highway bridge projects.

· Stay Cable Bridges & Suspension Structures: Providing reliable, high-fatigue resistant anchoring for heavy structural loads.

· Box Girder & Balanced Cantilever Bridges: Ensuring longitudinal, transverse, and vertical prestressing.

 Commercial Buildings & Industrial Structures

· Large-Span Buildings: Ideal for shopping malls, airport terminals, and parking structures requiring column-free spaces and reduced floor thickness.

· Industrial Silos & Tanks: Used in circumferential post-tensioning for LNG storage tanks, cement silos, water reservoirs, and nuclear containment vessels.

· Transfer Girders & Deep Beams: Supporting heavy structural transfers in high-rise buildings.

Geotechnical & Heavy Engineering

· Ground & Rock Anchors: Used in slope stabilization, deep foundation pit support, and tie-back anchoring for retaining walls.

· Heavy Lifting & Moving: Providing temporary or permanent anchorage for lifting mega-structures, offshore platforms, and heavy machinery.

· Dam Rehabilitation: Strengthening and stabilizing concrete gravity dams and spillway structures.
