Advantage
1. Mechanical key-locking effect enables shallow embedment depths with high load-bearing capacity.
2. Near-zero expansion stress allows anchoring at minimal edge distances.
3. Ensures maximum deployment of expansion segments for optimal force transmission.
4. Immediate full design load capacity after installation – no curing time required. TEDUN undercut mechanical anchors utilize high-grade carbon steel sourced from certified steel mills for traceable quality assurance. Exceeding ISO 898-1 Grade 8.8 mechanical properties, they achieve Class S safety certification through rigorous testing including:
Seismic compliance (ACI 355.4 Category 3)
2 million fatigue cycles (EN 1992-4 dynamic loading)
Fire resistance (EOTA TR 048 @ 90min/800°C)
Product enhancements feature redesigned geometry for optimal interlock engagement and permanent TEDUN laser marking on every anchor for authenticity tracking.
Application
1. Structural Reinforcement in Construction
Undercut mechanical anchors specialize in reinforcing existing concrete structures and seismic retrofitting. They are ideal for high-demand applications such as beam-column joint strengthening, curtain wall mullion installations, and base isolator fixations. Their mechanical interlock mechanism retains over 85% pullout resistance in cracked concrete (compared to <50% for conventional anchors), complies with GB 50011 seismic code requirements for 2 million fatigue load cycles, and serves as the core anchoring solution for skyscraper renovations and prefabricated building connections.
2. Heavy Industrial Equipment Anchoring
For securing power generator sets, precision machine tools, and chemical pipelines, these anchors utilize high shear capacity (>50 kN @ M20 per VDI 2230) to suppress equipment vibration displacement. The thrust sleeve-driven key expansion mechanism creates rigid connections that eliminate micro-vibration impacts on operational accuracy. They excel in impact-load scenarios like compressors and hydraulic presses, ensuring uninterrupted production stability.
3. Transportation Infrastructure
These anchors dominate dynamic-load environments including bridge expansion joints, tunnel segment repairs, and high-speed rail catenary mast foundations. Certified for -40°C to +80°C temperature extremes (EN 1992-4), they maintain 3D mechanical interlock through freeze-thaw cycles and train vibrations. With shear resistance reaching 100 kN @ M24 (EN 50122 standard), they significantly reduce track-side maintenance frequency.
4. Energy & Power Engineering
Addressing corrosion resistance and seismic demands in wind turbine grout zones, substation GIS equipment, and nuclear plant supports, they accommodate Dacromet/hot-dip galvanized coatings (ISO 12944 C5M). In coastal and nuclear environments, the inverted-cone cavity interlock delivers reliable pullout strength (160 kN @ M24) and complies with IEC 61400-6 wind certification, resolving critical failure points of bonded anchors in grout layers.
