As a specialized manufacturer with over 25 years of experience (Anping County Boli Hardware Wiremesh Products Factory, established 1998), we are proud to introduce our Elastic Rail Clip for Urban Metro Rail Track Fastening System. This clip is engineered to deliver exceptional holding force and fatigue resistance, ensuring safe and stable rail alignment in high-density metro environments. Our factory has supplied these components to metro projects across North America, Europe, and Southeast Asia, with an annual export value exceeding US$5 million.
Product Overview
The Elastic Rail Clip is a critical component of the rail fastening system, designed to securely clamp the rail to the baseplate while allowing controlled elastic deformation. This maintains consistent gauge, absorbs dynamic loads, and reduces noise and vibration — essential for urban metro tracks where passenger comfort and track durability are paramount. Manufactured from premium spring steel, each clip undergoes strict quality control to meet international standards for metro rail applications.
Key Features & Benefits
- Superior Elasticity — The clip's unique geometry provides optimal clamping force (typical 8-12 kN per clip) while maintaining flexibility to accommodate rail thermal expansion and contraction.
- High Fatigue Strength — Tested for over 3 million cycles without failure, ensuring long service life even under heavy metro traffic.
- Corrosion Resistance — Available with black oxide, phosphating, or Dacromet coating, offering rust protection in humid tunnel environments.
- Easy Installation — Designed for simple manual or hydraulic tool insertion, reducing labor time on site.
- Compatibility — Fits standard UIC60, 54E1, or other metro rail profiles with corresponding baseplate designs.
- Customizable Dimensions — Our factory can produce clips according to your specific drawings or samples, with lead times as short as 15 days.

Frequently Asked Questions
-
What material is used for the rail clip?
We use premium spring steel (60Si2Mn or 55Cr3) to ensure high elasticity and fatigue resistance. Other materials are available upon request. -
Can the clip be customized for different rail profiles?
Yes, we can produce clips according to your rail profile (UIC60, 54E1, etc.) and baseplate design. Please provide drawings or samples. -
What is the lead time for bulk orders?
Typically 15-25 working days after sample approval. Rush orders can be expedited. -
How do you ensure corrosion resistance in underground metro environments?
We offer multiple surface treatments: black oxide, phosphating, and Dacromet coating. The Dacromet option provides excellent salt spray resistance (up to 500 hours). -
Is the clip easy to install and remove?
Yes, our clip is designed for easy installation using standard tools (manual or hydraulic clip inserter). Removal is also straightforward for maintenance. -
What is the typical clamping force?
Standard range is 8-12 kN per clip. We can adjust the force by modifying the clip geometry or material thickness. -
Do you provide samples for testing?
Yes, we offer free samples for qualification. The buyer only pays for shipping. Samples are available within 7 days. -
What quality control measures do you have?
Every batch undergoes hardness testing, dimensional inspection, and fatigue testing. We also provide a material test certificate upon request.
