Concrete Anchor Hook
Products Description
Concrete Anchor Hook is a mechanical anchoring fastener designed for suspension and support installation in concrete substrates.
Unlike standard expansion bolts that provide threaded attachment points, a concrete anchor hook integrates an expansion anchoring mechanism with a closed-hook suspension structure, allowing direct connection of:
Threaded rods
Suspension chains
Wire ropes
Pipe hangers
Cable support hardware
The product is widely used in electrical installation, HVAC systems, cable tray support structures, industrial maintenance platforms, and commercial building infrastructure projects.
The anchoring mechanism converts installation torque into radial expansion force, creating a mechanical interlock between the expansion sleeve and the concrete wall.
Core Technical Features: Breaking Through the Performance Limitations of Traditional Anchors
Multi-lobed Interlocking Anchoring Technology
Utilising a 3-6 lobe expansion tube design, it expands simultaneously upon tightening, forming multi-point interlocking with the concrete hole wall. The contact area is increased by 40% compared to traditional sleeve-type expansion hooks, significantly enhancing pull-out resistance.
Barbed Anti-slip Locking Technology
The expansion tube surface is equipped with serrated barbs that embed into the concrete substrate after expansion, forming a mechanical self-locking mechanism. The probability of loosening in vibration environments approaches zero, far exceeding that of ordinary smooth expansion tubes.
Stress Dispersion Optimisation Technology
Through finite element simulation, the expansion tube wall thickness and expansion angle are optimised, ensuring that the anchoring stress is evenly distributed within the concrete, avoiding substrate cracking caused by localised stress concentration.
Environmental Resistance Enhancement Technology
Employing a dual treatment of "substrate rust prevention + surface corrosion prevention," expansion hook meets salt spray test standards for over 120 hours and maintains stable performance in harsh environments such as -30℃ to 80℃, humidity, and outdoor conditions.
Materials Science and Structural Innovation: A Perfect Unity of Micro and Macro Perspectives
1. High-Performance Material System
Utilising low-alloy high-strength steel, precise heat treatment processes achieve the optimal balance of strength and toughness.
Hot-dip galvanising provides long-lasting electrochemical protection with precisely controlled zinc layer thickness.
Special passivation technology significantly enhances corrosion resistance while maintaining a stable coefficient of friction.
2. Innovative Structural Design Philosophy
wall anchor hook geometry optimisation based on finite element analysis ensures smooth stress flow transmission.
Asymmetric expansion plate design ensures ideal expansion effects in various concrete substrates.
Precise thread lead design guarantees reliable anti-loosening performance while ensuring installation efficiency.

Engineering Considerations for Concrete Installation
Concrete Strength
Higher substrate strength generally provides greater pull-out resistance.
Embedment Depth
Insufficient embedment depth may reduce anchoring performance.
Edge Distance
Anchors installed too close to concrete edges may increase cracking risk.
Load Direction
Vertical loads and side loads affect anchor performance differently and should be considered during system design.
