As a professional manufacturer from Anping County Boli Hardware Wiremesh Products Factory (established 1998), we specialize in manufacturing high-quality spring clips designed specifically for railway sleepers used in high-speed rail track elastic fastening systems. Our spring clips are engineered to provide reliable clamping force, ensuring track stability and safety even under extreme dynamic loads. With over 20 years of experience and annual export value exceeding US$5 million, we serve global markets including North America, Europe, and Southeast Asia, delivering consistent performance and durability.
These spring clips are critical components in elastic fastening systems, maintaining the correct gauge and preventing rail creep. They are made from premium spring steel, heat-treated to achieve optimal elasticity and fatigue resistance, meeting international standards for high-speed rail applications.
Key Features & Technical Specifications
- Material Excellence: Manufactured from 60Si2Mn or 55Cr3 spring steel, offering high yield strength and excellent fatigue life, suitable for heavy-duty railway environments.
- Precision Heat Treatment: Controlled quenching and tempering process ensures hardness of HRC 40-48 and tensile strength ≥ 1200 MPa, providing consistent clamping force over years of service.
- Corrosion Resistance: Available with black oxide, zinc plating, or Dacromet coating to resist rust and extend service life in humid or coastal areas.
- Versatile Compatibility: Designed to fit UIC60, UIC54, and 50kg/m rails, compatible with standard concrete sleepers and elastic fastening systems (e.g., SKL, W-type).
- Dynamic Performance: Optimized geometry to reduce stress concentration and maintain stable clamping force under high-frequency vibration in high-speed rail tracks.
- Easy Installation: Simple clip-on design reduces installation time and labor costs, with no need for special tools.
