Stressing-End Round Anchorage System for Post-Tensioned Prestressed Concrete Structures
The Stressing-End Round Anchorage System is a critical element in modern post-tensioned prestressed concrete construction, engineered to securely hold multiple PC steel strands at the live end during the tensioning phase. This anchoring solution ensures efficient and reliable transfer of high tensile forces into structural elements such as beams, slabs, and bridge decks—enhancing overall strength, durability, and long-term performance. Designed with precision engineering and material integrity, it supports infrastructure resilience under dynamic loads while meeting international standards for safety and serviceability.
Manufactured by Chunpeng Group—a globally recognized leader in prestressed concrete solutions with over three decades of specialized experience—the system reflects a deep commitment to innovation, quality control, and sustainable construction practices. Our expertise spans the full spectrum of prestressing technologies, from ultra-high-strength steel strands to corrosion-resistant anchorage components, ensuring compatibility across diverse environmental conditions and project requirements worldwide.
Key Features:

This anchorage system plays an essential role in enabling advanced structural designs that maximize span lengths, reduce material usage, and minimize life-cycle costs. It integrates seamlessly with post-tensioning methodologies used in bridges, parking structures, high-rise buildings, industrial floors, and precast elements. By maintaining consistent stress distribution throughout the tendon network, it prevents premature failure modes such as bond slippage or anchor pull-out—critical factors in ensuring compliance with ISO, ASTM, EN, and AASHTO standards.
Its versatility makes it ideal for use in seismic zones, coastal regions, and areas exposed to aggressive chemical environments where traditional anchoring systems may degrade prematurely. The system’s modular configuration allows customization based on the number of strands, diameter specifications, and required ultimate tensile strength levels, making it suitable for both small-scale civil works and large-scale infrastructure projects.
Users consistently report improved constructability and reduced downtime due to fewer adjustments needed during tensioning operations. Many engineers appreciate how this anchorage enhances predictability in post-tensioning outcomes, leading to better alignment between theoretical design assumptions and real-world structural behavior. Its proven track record in international markets—from Europe to North America and Southeast Asia—demonstrates adaptability across different regulatory frameworks and climatic challenges.
Frequently Asked Questions:
What distinguishes this anchorage system from standard wedge-type anchors? It offers enhanced gripping capability for multi-strand assemblies and is specifically tailored for the stressing-end application, where precise force application and uniform load distribution are paramount. Unlike generic anchors, our system accounts for variations in strand geometry and tension profiles, reducing the risk of uneven loading or localized stress concentrations.
Is it compatible with unbonded tendons? Yes, the round anchorage system is fully compatible with unbonded PC strands, providing secure fixation without compromising the tendon’s ability to move freely within its duct during tensioning and subsequent grouting processes.
How does it contribute to sustainability in construction? By enabling longer spans and reduced concrete volumes, it contributes to lower carbon emissions per unit of structural output. Additionally, its durable materials and low-maintenance nature extend service life, minimizing the need for replacement or repair—key benefits in green building certification programs like LEED or BREEAM.
Can it be customized for specific project needs? Absolutely. We offer custom configurations based on project-specific parameters such as strand count, tensile strength grade, corrosion protection level, and installation constraints—ensuring optimal integration into any prestressed concrete framework.
