High-Performance Prestressed Anchorage Systems: YJM 13 and YJM 15 for Modern Construction
Engineered for structural excellence, the YJM 13 Prestressed Anchorage System and YJM 15 Holding System represent cutting-edge solutions in post-tensioning technology. Designed by Chunpeng Group—a trusted manufacturer with over three decades of expertise in prestressed concrete (PC) materials—these anchoring systems deliver unmatched strength, durability, and precision for critical infrastructure projects worldwide. Whether applied in bridges, high-rise buildings, or industrial facilities, both systems ensure reliable tendon fixation under extreme tensile loads while minimizing stress concentrations and enhancing long-term performance.
The YJM 13 system excels in efficient load transfer through its robust, modular design, making it ideal for standard to demanding civil engineering applications. Its optimized geometry and high-strength components allow seamless integration into reinforced concrete elements, ensuring consistent performance across diverse environmental conditions. Meanwhile, the YJM 15 Holding System is specifically engineered for harsh environments, offering superior resistance to corrosion, weathering, and mechanical fatigue—making it a preferred choice for coastal, marine, or chemically aggressive settings where longevity and reliability are paramount.
Both anchorage systems are manufactured to meet international quality standards, including ISO and ASTM benchmarks, guaranteeing compatibility with various PC steel strands such as galvanized, unbonded, ultra-high-tensile, and anti-corrosion variants. This ensures flexibility in project-specific configurations while maintaining compliance with global construction codes. The use of advanced metallurgy and surface treatments enhances fatigue life and reduces maintenance needs, aligning with sustainable development goals in modern infrastructure planning.
Key features include:
• Modular assembly for easy installation • High tensile capacity for heavy-duty applications • Corrosion-resistant coatings for extended service life • Compatibility with bonded and unbonded tendon systems • Precision-engineered gripping mechanisms for secure strand retention
These anchoring solutions are widely used in bridge decks, parking structures, precast panels, offshore platforms, and seismic-resistant frameworks. Their ability to maintain tension integrity over time makes them essential for any project requiring long-term stability, safety, and minimal degradation. With increasing demand for resilient infrastructure, especially in regions prone to natural hazards, the YJM series offers engineers a dependable, future-proof option for prestressing applications.
Users consistently praise the ease of installation, reduced labor requirements, and improved structural efficiency compared to traditional anchorage methods. Many engineers note that the systems’ adaptability allows for customization without compromising performance, which is particularly valuable in complex architectural designs or retrofitting existing structures.
Common questions often revolve around material compatibility, expected lifespan under different climatic conditions, and installation best practices. The YJM 13 and YJM 15 systems are compatible with most types of PC steel strands available globally, including those with enhanced weather protection. With proper design and application, these anchorage systems can exceed 50 years of service life in moderate climates, even longer in controlled environments. Installation should always follow technical guidelines provided by the manufacturer to maximize load distribution and prevent premature failure.
