As a fully certified bonded injection anchor strictly covered under official ETA Certificate ETA-23/0370 issued by ETA-Danmark, the MT500 chemical anchoring system complies fully with EU Construction Products Regulation (EU No 305/2011) and carries valid CE marking, making it a code-approved anchoring solution for global concrete construction projects.
This complete bonded anchor set consists of two-component injection mortar cartridge, 10.9-grade 35CrMo threaded rods ranging from M10 to M30, matching galvanized nuts and washers. Designed for permanent post-installed fixing in cracked & uncracked normal concrete C20/25 to C50/60, it delivers stable bearing capacity under static, quasi-static loads and seismic actions up to performance category C2, meeting rigorous international seismic design standards.
Verified through full third-party lab testing documented in the 17-page official ETA dossier, MT500 supports ultra-long service life options of 50 years and 100 years. It adapts to complex harsh working conditions, including dry interior environments, high-humidity coastal zones, wet boreholes and fully flooded drill holes (excluding seawater). The system maintains reliable anchoring performance within a wide temperature spectrum from -40°C up to +60°C, with stable bond strength even under long-term high-temperature exposure.
Outstanding core mechanical performance validated in ETA test data:
1. High tensile & shear resistance: M10–M30 10.9-grade studs deliver up to 561kN characteristic tensile resistance and 281kN shear resistance, with stable bond stress values for both cracked and uncracked concrete under dry, wet or water-submerged installation conditions.
2. Superior long-term stability: Optimized anti-creep performance with standardized sustained load reduction factors, effectively preventing anchor displacement over decades of service.
3. Wide construction adaptability: Clear standardized installation parameters for drilling diameter, embedment depth, minimum slab thickness and tightening torque for each size. Complete curing time schedules cover ambient temperatures from -5°C to above 30°C, allowing construction under low winter temperatures. Step-by-step standardized hole cleaning and injection operation procedures are specified to guarantee consistent installation quality.
Recognized and adopted for world-class high-standard landmark infrastructure projects with the strictest safety thresholds:
- El-Dabaa Nuclear Power Plant, Egypt
Africa’s flagship Generation III+ nuclear energy facility built to top global nuclear safety codes. Multiple auxiliary structures operate under long-term seawater immersion and humid marine corrosion environments. ETA-certified MT500 bonded anchors were selected for critical submerged component anchoring, relying on its low water absorption and corrosion-resistant bonding performance to secure lifelong structural stability.
- Chashma-C5 Nuclear Power Plant, Pakistan
Pakistan’s core national nuclear strategic project, demanding extreme long-term anti-creep performance under continuous static loads. MT500 bonded anchors with verified 100-year service life data are specified for all permanent structural reinforcement fixing.
- Khor Al-Zubair Submerged Tunnel, Iraq
Iconic cross-water tunnel project in the Middle East located in heavily corrosive coastal surroundings. MT500 chemical anchors provide durable anchoring for tunnel lining and underwater auxiliary concrete members, fully compliant with EU anchoring design codes.
Major domestic key engineering projects that trust MT500 bonded anchoring system:
- Xudabao Nuclear Power Plant
State-level key nuclear power project in Northeast China with ultra-rigorous nuclear safety specifications. ETA & CE certified MT500 bonded anchors are widely deployed for permanent structural anchoring and secondary reinforcement of nuclear island auxiliary buildings.
- New Link Line Project between Guangzhou Station and Guangzhou South Station, undertaken by China Railway 18th Bureau Group Co., Ltd.
A vital rail transit artery of the Guangdong-Hong Kong-Macao Greater Bay Area, featuring super-large-diameter shield tunnels with complicated soft soil and cross-river geological conditions. MT500 bonded anchors ensure high-strength, long-term stable anchoring for tunnel lining, bridge piers and underground auxiliary structures under frequent dynamic train loads.
- Lot 2 Pre-works of Hangzhou Xiaoshan Airport Railway Hub & Connection Project, undertaken by China Railway 14th Bureau Group Co., Ltd.
A landmark air-rail integration transportation project crossing Qiantang River, with deep-buried underwater shield tunnels bearing huge water and soil pressure. MT500 ETA-certified bonded anchors are adopted for permanent structural reinforcement of tunnel segments, station main structures and viaduct components to meet strict anti-fatigue and anti-corrosion requirements.
