China Elastic Rail Clip Suppliers - Durable Factory-Made Fasteners for EU EN 13481 & US AREMA Standards
Basic Information
These elastic rail clips (also known as spring clips) are core elastic clamping components of EU/US standard-compliant rail fastening systems, designed to apply continuous and stable clamping force on rail feet, buffer wheel-rail impact, and prevent lateral or longitudinal rail displacement under long-term dynamic loads.
Standards & Compatibility
- EU Markets (EN 13481): Forged from 60Si2MnA spring steel. Includes SKL series omega-shaped clips and Pandrol E-type clips. Suitable for 350km/h high-speed rails, 25t axle-load heavy-haul lines, and urban transit. Fully compatible with Vossloh and Pandrol mainstream fastening systems.
- North American Markets (AREMA Ch. 5): High-strength pre-assembled Pandrol Fastclips for 40t axle-load heavy-haul freight lines, supporting toolless quick installation to cut on-site construction costs.
Performance & Testing
- Dynamic Load Performance: Passed 5 million dynamic load cycle tests with less than 5% clamping force loss and no permanent deformation.
- Corrosion Resistance: Applied with Dacromet or hot-dip galvanized anti-corrosion coatings, passing 1500+ hour neutral salt spray tests.
- Climate Adaptability: Engineered to adapt to extreme weather conditions ranging from -45℃ to 80℃.
Specialized Features
- Signal Protection: Insulation-sheathed versions are available for electrified lines, providing ≥10MΩ insulation resistance to avoid railway signal interference.
- Tailored Engineering: Custom models with specified clamping force and sizes are available for special project demands.
Frequently Asked Questions (FAQ)
1. What materials are used to manufacture these elastic rail clips?
For EU markets conforming to EN 13481 specifications, the clips are forged from high-grade 60Si2MnA spring steel and undergo strict quenching and tempering heat treatment.
2. Which rail fastening systems are these clips compatible with?
They are fully compatible with Vossloh and Pandrol mainstream fastening systems. This includes SKL series omega-shaped clips, Pandrol E-type clips, and high-strength pre-assembled Pandrol Fastclips.
3. How do the clips perform under dynamic loads?
All products undergo rigorous testing, passing 5 million dynamic load cycle tests with less than 5% clamping force loss and no permanent deformation.
4. What coatings are applied for corrosion protection?
The clips are finished with Dacromet or hot-dip galvanized anti-corrosion coatings. They pass 1500+ hour neutral salt spray tests, allowing them to adapt to extreme weather from -45℃ to 80℃.
5. Are there options available for electrified railway lines?
Yes, we offer insulation-sheathed versions for electrified lines that provide ≥10MΩ insulation resistance to prevent railway signal interference.
6. Can the rail clips be customized for specific projects?
Yes, custom models with specified clamping forces and dimensions can be engineered and manufactured to meet your unique project requirements.
