Bartec Coupler | Upset Forged Grade 1 Rebar Coupler for Seismic Structures

Full-Strength Grade 1 Mechanical Connection The upset forging process ensures that the threaded section is stronger than the original bar, allowing the coupler to achieve 100% bar break performance and comply with Grade 1 connection standards. Excellent Slip Resistance (0.1 mm Slip Test Pass) Precision thread engagement and tight axial alignment enable the system to pass the 0.1 mm slip test, ensuring minimal axial deformation and high stability under load. Outstanding Fatigue Resistance Validated through 3,500,000 cycles of fatigue testing, the coupling system maintains long-term performance under repeated dynamic loading, suitable for highways, railways, and heavy-load structures. Superior Seismic Performance Designed for seismic regions, the coupler provides high ductility, consistent energy dissipation, and stable load-bearing performance during earthquakes. Reliable Quality & Easy Installation Uniform thread profile and precision machining ensure consistent engagement. The system requires no torque-controlled tightening, enabling fast and error-free installation on construction sites.
