Elastic Rail Clips from China Suppliers - Factory-Compliant with 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.
For EU markets conforming to EN 13481 specifications, clips are forged from 60Si2MnA spring steel, with common models including 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 routes, fully compatible with Vossloh and Pandrol mainstream fastening systems.
For North American markets following AREMA Chapter 5 rules, high-strength pre-assembled Pandrol Fastclips are required for 40t axle-load heavy-haul freight lines, supporting toolless quick installation to cut on-site construction costs. All products undergo strict quenching and tempering heat treatment, passing 5 million dynamic load cycle tests with less than 5% clamping force loss and no permanent deformation. Dacromet or hot-dip galvanized anti-corrosion coatings are applied, passing 1500+ hour neutral salt spray tests to adapt to extreme weather from -45℃ to 80℃. Insulation-sheathed versions are available for electrified lines, providing ≥10MΩ insulation resistance to avoid railway signal interference, and custom models with specified clamping force and size are available for special project demands.

Frequently Asked Questions
What standards do these elastic rail clips comply with?
Our elastic rail clips comply with EU standard EN 13481 specifications (such as SKL series and Pandrol E-type clips) and North American AREMA Chapter 5 regulations (such as high-strength pre-assembled Pandrol Fastclips).
What material is used to manufacture the rail clips?
For EU standard-compliant clips, they are forged from high-quality 60Si2MnA spring steel and undergo strict quenching and tempering heat treatments to ensure optimal elastic clamping force.
What are the application limits for these rail fastening clips?
They are highly suitable for 350km/h high-speed railways, 25t axle-load heavy-haul lines, 40t axle-load heavy-haul freight lines, and urban transit routes, being fully compatible with Vossloh and Pandrol systems.
How durable are these spring clips under dynamic loads?
These clips have passed 5 million dynamic load cycle tests, showing less than 5% clamping force loss and zero permanent deformation under long-term dynamic loading.
What anti-corrosion treatments are available?
We apply Dacromet or hot-dip galvanized coatings. These coatings pass 1500+ hour neutral salt spray tests, allowing the clips to perform in extreme temperatures ranging from -45℃ to 80℃.
Can these clips be used on electrified railway lines?
Yes, we provide insulation-sheathed versions for electrified lines that offer ≥10MΩ insulation resistance to prevent railway signal interference.
