Advantage
1. Instant Load-Bearing Capacity
Expansion anchor bolts achieve immediate locking via mechanical expansion, allowing instant load-bearing (tension/shear) after installation. This eliminates the curing wait time required for chemical anchors, reducing construction cycles by over 30% in urgent repairs or time-critical projects.
2. Exceptional Mechanical Performance
Utilizing high-strength alloy steel (Grade 8.8/10.9) and optimized expansion mechanisms, they deliver tensile strength up to 250kN (M30 size) and shear resistance exceeding 120kN. Certified to EN 1992-4 for seismic performance, they maintain >50-year service life under vibration/impact loads (validated per ISO 898-1 fatigue tests).
3. Revolutionary Installation Efficiency
Tool-free hammer-drive installation (e.g., impact-type anchors) tolerates drilling deviations of ±2mm. Compared to chemical anchors, this reduces 5 steps (hole cleaning, resin injection, etc.), significantly easing overhead/vertical operations and boosting efficiency by 40%.
4. Extreme Environmental Resilience
Corrosion Resistance: A4-316 stainless steel / 50μm hot-dip galvanizing withstands salt spray (ISO 9227: 1000h+)
Temperature Tolerance: Specialty steel for -60°C to all-metal structures at 300°C (verified per ISO 9142 thermal cycling)
Waterproof Sealing: Enclosed expansion sleeve design meets ETAG 001 Annex E for long-term immersion。
5. Lifecycle Cost Efficiency
Unit cost is 30% lower than chemical anchors, with zero maintenance or reinspection due to all-metal anti-aging construction. By eliminating resin equipment and curing time during installation, total project costs drop 15%-25% (IBAU Research Institute data).
Application
Core Characteristics & Suitable Substrates: Expansion anchors are mechanical anchors that achieve high-load-bearing fixation by expanding to generate friction and locking forces. They are primarily suitable for solid, dense substrates such as concrete (optimal performance), solid brick, and natural stone. They are not suitable for hollow bricks, aerated concrete blocks, plasterboard, timber, or other low-strength or loose substrates.
1. Core Applications in Building Structures: Within the construction field, they are essential components for structural fixing and heavy-duty installations. They are used to fix steel structures (beams, columns), install curtain wall embedments/post-installed anchors, secure heavy door/window frames, fasten stair handrails/guardrails, mount pipe/cable tray supports, install elevator guides, and anchor heavy equipment bases (e.g., pumps, transformers) in floors/walls, as well as for exterior wall decorations/billboards.
2. Industrial Equipment & Heavy Facility Fixing: In industrial settings, expansion anchors are fundamental for ensuring reliable equipment operation. They are primarily used to securely anchor various heavy machinery (machine tools, generators, pumps), production line supports, large industrial piping systems, storage tanks/containers, as well as heavy-duty warehouse shelving and overhead crane rails to concrete foundations or structures, preventing displacement or overturning.
3. Critical Connections in Infrastructure: In infrastructure sectors like bridges, tunnels, power, transportation, and water conservancy, they play a vital role in critical connections and safety assurance. Typical applications include fixing bridge expansion joints/bearings, tunnel equipment (lighting, ventilation, cable supports), power facility bases (transformers, switchgear), transportation facilities (road guardrails, signs, traffic lights, railway equipment), airport navigation devices, and hydraulic gates/pump station equipment.
4. Civil/Commercial Uses: In civil and commercial spaces, they are used for applications requiring strong anchoring, such as installing large chandeliers/ceiling fans, heavy wall-mounted TVs, high/upper kitchen cabinets (especially when fully loaded), bathroom grab bars, heavy bookshelves/racks, fitness equipment, outdoor awnings, and heavy-duty retail displays/billboards.
Key Considerations: Precise drilling and strict adherence to installation specifications (e.g., torque control) are essential. Substrate quality must be ensured (no cracks or looseness). Compliance with building codes and safety factors is mandatory for critical structural safety applications (e.g., curtain walls, equipment bases), involving structural engineers when necessary.
