The BJM Flat Type Anchors are a premium component of the JM Anchorage System, engineered for high-performance post-tensioned prestressed concrete applications. Designed to securely anchor steel strands with tensile strengths up to 2000MPa, these anchors support both standard diameters—Φ12.70mm and Φ15.20mm—and offer reliable load transfer in demanding structural environments. Whether used in residential slabs, commercial buildings, or infrastructure projects, this anchoring solution ensures durability, precision, and safety. This system includes tension-end components such as BM and HBM Anchors, along with fixed-end options like Type H and Type P, making it ideal for multi-strand assemblies ranging from 2 to 5 strands per unit. The flat-type design enhances ease of installation while maintaining optimal stress distribution across the strand bundle—a critical factor in preventing premature failure and ensuring long-term performance. Engineered for compatibility with ultra-high-strength PC strands, including galvanized and corrosion-resistant variants, the BJM Anchorage System supports modern construction demands for resilience against environmental degradation and mechanical fatigue. Developed by Chunpeng Group—a globally recognized manufacturer with over three decades of expertise in prestressed concrete materials—this anchorage solution reflects a commitment to innovation, quality control, and sustainable engineering practices. Beyond traditional prestressing systems, the company also offers
Unbonded PC Strand solutions, weather-resistant reinforcement products, and photovoltaic mounting systems tailored for integrated energy-efficient structures. Each product line is rigorously tested to meet international standards, ensuring compliance with global specifications for civil engineering projects. Ideal for negative moment regions in bridge decks, parking garages, and precast elements, the BJM Flat Type Anchors provide engineers and contractors with versatile, field-proven performance. Their modular configuration allows seamless integration into complex geometries without compromising structural integrity. With minimal maintenance requirements and proven resistance to dynamic loading conditions, these anchors contribute to reduced lifecycle costs and enhanced project longevity. Users consistently praise the system's robustness under extreme loads, particularly in seismic zones where ductility and energy dissipation are paramount. Contractors appreciate the straightforward installation process, which minimizes downtime on-site and reduces labor intensity compared to conventional alternatives. Engineers highlight the system’s adaptability to both new builds and retrofitting scenarios, especially when upgrading older concrete structures with modern prestressing techniques. Common questions often revolve around compatibility with different strand types, ease of assembly, and expected service life under various climatic conditions. The BJM system is compatible with a wide range of
Prestressed Steel strands—including normal and ultra-high-tensile strength variants—and has demonstrated exceptional durability in humid, salty, and industrial environments. Installation typically requires basic tools and trained personnel, though detailed technical documentation is available for reference. With proper handling and adherence to recommended torque values, these anchors can exceed 50 years of service life in most applications. For professionals seeking durable, efficient, and future-ready anchoring solutions, the BJM Flat Type Anchors represent a strategic choice in modern construction. They combine decades of manufacturing excellence with cutting-edge design principles, delivering unmatched value for infrastructure, transportation, and building projects worldwide.
