Elastic Rail Clips from China Factory - Compliant with EU EN 13481 & US AREMA, Reliable Suppliers for Rail Fasteners
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 Standards & Design
Conforms to EN 13481 specifications, forged from 60Si2MnA spring steel. Includes SKL series omega-shaped clips and Pandrol E-type clips compatible with Vossloh and Pandrol fastening systems.
US Standards & Heavy Haul
Complies with AREMA Chapter 5 rules. Features high-strength pre-assembled Pandrol Fastclips for 40t axle-load freight lines, supporting toolless quick installation.
Rigorous Testing
Undergoes strict quenching and tempering heat treatment. Passed 5 million dynamic load cycle tests with less than 5% clamping force loss and zero permanent deformation.
Weatherproof & Insulation
Dacromet or hot-dip galvanized coatings pass 1500+ hour neutral salt spray tests (-45℃ to 80℃). Insulation-sheathed versions provide ≥10MΩ resistance to prevent signal interference.
Frequently Asked Questions
What standards do these elastic rail clips comply with?
Our rail clips comply with EU standards conforming to EN 13481 specifications, as well as North American standards following AREMA Chapter 5 rules.
What materials and models are available for the EU market?
For the EU market, clips are forged from 60Si2MnA spring steel. Common models include SKL series omega-shaped clips and Pandrol E-type clips, compatible with Vossloh and Pandrol mainstream fastening systems.
How do the clips perform under heavy-haul dynamic loads?
They pass 5 million dynamic load cycle tests with less than 5% clamping force loss and no permanent deformation, supporting up to 40t axle-load heavy-haul freight lines.
How corrosion-resistant are these spring clips in extreme weather?
All products feature Dacromet or hot-dip galvanized anti-corrosion coatings, passing 1500+ hour neutral salt spray tests to operate reliably in temperatures from -45℃ to 80℃.
Are there insulated versions for electrified transit systems?
Yes, insulation-sheathed versions are available for electrified lines, offering ≥10MΩ insulation resistance to prevent railway signal interference.
Can you customize the clamping force and dimensions?
Yes, custom models with specified clamping force and sizing can be manufactured to meet unique project demands.
