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.
EU Market Standards
Conforming to EN 13481 specifications, forged from 60Si2MnA spring steel. Includes SKL series omega-shaped and Pandrol E-type clips. Suitable for 350km/h high-speed rail.
North American Standards
Following AREMA Chapter 5 rules, utilizing high-strength pre-assembled Pandrol Fastclips for 40t axle-load heavy-haul freight lines.
Durability & Testing
Passed 5 million dynamic load cycle tests with
Extreme Protection
Dacromet or hot-dip galvanized coatings (1500+ hour salt spray test). Operational range from -45℃ to 80℃ with ≥10MΩ insulation resistance.
Frequently Asked Questions
What materials are used for the EU market rail clips?
For markets conforming to EN 13481 specifications, the clips are forged from high-quality 60Si2MnA spring steel to ensure maximum elasticity and durability.
Are these clips compatible with Vossloh and Pandrol systems?
Yes, our clips are fully compatible with mainstream fastening systems, including the Vossloh SKL series and Pandrol E-type and Fastclip systems.
How do the clips perform under dynamic heavy loads?
All products pass 5 million dynamic load cycle tests. They maintain structural integrity with less than 5% clamping force loss and no permanent deformation.
What kind of anti-corrosion treatment is applied?
We apply Dacromet or hot-dip galvanized coatings, which pass 1500+ hour neutral salt spray tests, making them suitable for extreme environments.
Can these clips be used on electrified railway lines?
Yes, insulation-sheathed versions are available that provide ≥10MΩ insulation resistance to prevent railway signal interference.
What is the temperature tolerance for these rail clips?
The clips are designed to adapt to extreme weather conditions ranging from -45℃ to 80℃ without compromising clamping performance.
