DM Type Prestressed Anchorage: High-Performance Solution for Modern Infrastructure
The DM type prestressed anchorage is a specialized mechanical connector engineered to securely transfer tensile forces from high-strength steel tendons into concrete elements within post-tensioned structures. This anchor system, also known as the upset head anchorage or DM anchor with head, plays a critical role in ensuring long-term structural integrity across demanding civil engineering applications such as bridges, skyscrapers, tunnels, and large-span industrial facilities. Designed for optimal load distribution and minimal deformation under extreme stress, it stands out among alternative anchoring solutions due to its superior grip, corrosion resistance, and ease of installation.
Manufactured by Chunpeng Group—a globally recognized producer of prestressed concrete (PC) materials with over three decades of expertise—the DM-type anchorage combines advanced metallurgical processing with precision engineering. Its unique design features an integral upset end that increases surface contact area and enhances frictional locking between the tendon and anchoring component. This results in significantly improved pull-out strength, reduced slippage, and enhanced fatigue performance, making it ideal for projects where durability and safety are non-negotiable.
Key characteristics include:
• High tensile capacity up to 250 kN per unit • Corrosion-resistant finish for extended service life • Compatible with both bonded and unbonded post-tensioning systems • Easy on-site assembly without specialized tools • Compliant with international standards including ASTM A418, EN 13197, and ISO 16602
Constructed from hardened alloy steel and treated with galvanization or anti-corrosion coatings, the DM anchorage resists environmental degradation while maintaining consistent mechanical properties even in aggressive climates. Unlike traditional wedge-type anchors, this system eliminates the need for complex grouting procedures, reducing labor costs and construction timelines. It is particularly effective when used with ultra-high-strength PC strands (up to 1860 MPa), offering seamless integration with modern prestressing technologies such as multi-strand tendons and precast segmental bridge components.
Common applications span transportation infrastructure—like highway viaducts and railway bridges—where dynamic loading and seismic resilience are essential. In high-rise buildings, these anchors support floor slabs, beams, and core walls, enabling longer spans and thinner sections without compromising stability. For tunnel linings and retaining structures, their robustness ensures reliable force transmission through variable soil conditions and groundwater exposure. Additionally, they serve as foundational elements in photovoltaic mounting systems, providing secure anchorage for solar panel arrays on commercial rooftops and ground-mounted installations.
Users consistently praise the DM anchorage for its reliability during installation, especially in tight spaces where conventional methods struggle. Engineers appreciate how the design minimizes stress concentration points, leading to fewer maintenance issues over time. Contractors report faster setup times and fewer rework incidents compared to older anchoring systems, contributing to overall project efficiency and cost savings. The product’s compatibility with various tendon types—including galvanized, weather-resistant, and unbonded strands—makes it a versatile choice for diverse global markets.
What sets the DM anchorage apart from competitors is not just its physical attributes but also its adaptability to evolving construction practices. As sustainability becomes increasingly important, this anchor supports green building goals by extending structure lifespan and reducing material waste from premature failures. Whether deployed in coastal regions prone to saltwater corrosion or arid environments with fluctuating temperatures, the DM type maintains peak performance throughout the expected service life of the structure.
Frequently asked questions often revolve around proper torque specifications, compatibility with different strand diameters, and whether additional protective measures are needed for harsh environments. While specific installation guidelines should be followed based on project requirements, the anchor's modular design allows for straightforward customization and inspection during construction phases. With rigorous quality control processes and extensive field testing, Chunpeng Group continues to lead the industry in delivering trusted, high-performance anchoring solutions tailored to modern engineering challenges worldwide.
