China Elastic Rail Clips Factory - Reliable Suppliers for EU EN 13481 & US AREMA Compliant 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. They are professionally 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.
Global Standards
Conforms to EN 13481 (EU) and AREMA Chapter 5 (US) specifications.
Premium Material
Forged from 60Si2MnA spring steel with strict quenching and tempering.
High Durability
Passed 5 million dynamic load cycles with
Anti-Corrosion
Dacromet or hot-dip galvanized coating, 1500+ hour salt spray test.
Signal Safety
Insulation-sheathed versions available with ≥10MΩ resistance.
Versatile Application
Suitable for high-speed rail, heavy-haul lines (up to 40t), and urban transit.
For EU markets, common models include SKL series omega-shaped clips and Pandrol E-type clips, fully compatible with Vossloh and Pandrol mainstream fastening systems. For North American markets, high-strength pre-assembled Pandrol Fastclips support toolless quick installation to cut on-site construction costs. These products adapt to extreme weather from -45℃ to 80℃, and custom models with specified clamping force and size are available for special project demands.
Frequently Asked Questions
Q1: Which international standards do your rail clips comply with?
Our rail clips are manufactured to meet EU EN 13481 specifications and North American AREMA Chapter 5 rules, ensuring compatibility with global railway infrastructures.
Q2: What material is used for manufacturing these elastic clips?
We use high-grade 60Si2MnA spring steel, which undergoes specialized quenching and tempering heat treatments to ensure maximum elasticity and strength.
Q3: How do the clips perform under heavy dynamic loads?
The clips have successfully passed 5 million dynamic load cycle tests, showing less than 5% loss in clamping force and no permanent deformation.
Q4: Are these clips suitable for extreme environmental conditions?
Yes, with Dacromet or hot-dip galvanized coatings, they pass 1500+ hour neutral salt spray tests and operate reliably in temperatures ranging from -45℃ to 80℃.
Q5: Do you provide solutions for electrified railway lines?
We offer insulation-sheathed versions that provide ≥10MΩ insulation resistance, effectively preventing railway signal interference on electrified tracks.
Q6: Can the clamping force be customized for specific projects?
Absolutely. We offer custom models where the clamping force and dimensions can be tailored to meet the specific requirements of unique railway projects.
