High-Performance YJM 13 and YJM 15 H-Type Prestressed Anchorage Systems for Modern Infrastructure
Engineered for durability, precision, and long-term structural integrity, the YJM 13 and YJM 15 H-type anchor systems represent a benchmark in post-tensioning technology. These advanced prestressed anchorage solutions are specifically designed for demanding civil engineering applications such as bridges, tunnels, high-rise buildings, and large-span industrial structures. As part of Chunpeng Group’s comprehensive range of pre-stressed concrete (PC) materials, these systems ensure optimal load transfer, corrosion resistance, and ease of installation—critical factors for global infrastructure resilience.
Key features include optimized load distribution across multiple strands, minimal maintenance requirements, and compatibility with both bonded and Unbonded PC Strand configurations. The H-type design enhances gripping efficiency while reducing stress concentration points, making it ideal for environments exposed to extreme weather conditions or heavy cyclic loading. Constructed from hardened alloy steel and treated with anti-corrosion coatings, each system maintains performance over decades under challenging operational conditions.
These anchorage units are not only engineered for strength but also for adaptability—supporting various tendon arrangements, including multi-strand configurations up to 15 strands (YJM 15). Whether used in seismic-prone regions or coastal zones where salt exposure is common, the YJM series offers reliable anchoring without compromising on safety margins. Their modular nature allows for efficient assembly during construction phases, minimizing downtime and labor costs—a key advantage for contractors managing tight project schedules worldwide.
Commonly referred to as "prestressed anchorage YJM 13 H type system" or "YJM 15 H type anchor system," this product line has been adopted globally in major transportation and utility projects. It integrates seamlessly with ultra-high tensile strength PC strands, galvanized variants, and weather-resistant formulations, offering engineers flexibility in material selection based on environmental and mechanical demands. For developers seeking durable, low-maintenance anchoring solutions, these systems provide a proven path to sustainable construction outcomes.
Users consistently highlight the system's reliability in complex projects, particularly when compared to older wedge-type anchors. One engineer noted: “The YJM 15 H-type anchor performed flawlessly in a bridge deck retrofit, even after five years of continuous traffic loads and temperature fluctuations.” Another user praised its quick installation process: “We saved nearly two weeks on our tunnel lining project by switching from traditional methods to this H-type anchorage setup.”
FAQs frequently asked include: What makes the YJM 13/15 H-type anchor different from standard wedge anchors? Answer: Its unique geometry and material composition allow for better grip and reduced slippage under dynamic loads. Can it be used with unbonded strands? Yes—it’s fully compatible with both bonded and unbonded post-tensioning systems. Is it suitable for marine environments? Absolutely—the anti-corrosion coating ensures longevity even in saline atmospheres.
