At Anping County Boli Hardware Wiremesh Products Factory, we are a seasoned manufacturer established in 1998, with annual export value reaching US$5–10 million. Our elastic rail clip fastening system is engineered to deliver reliable and durable performance for railway infrastructures worldwide. Every clip undergoes 100% NDT (Non-Destructive Testing) to ensure zero internal defects, and we provide comprehensive technical support to help you achieve optimal installation and long-term stability.
Our elastic rail clips are manufactured from high-grade spring steel, offering excellent fatigue resistance and clamping force retention. They are designed to secure rails firmly to sleepers while absorbing vibrations and impact loads, ensuring safe and smooth train operations. With a wide range of models and customizable options, our fastening system can be adapted to various rail profiles and environmental conditions.
Key Features & Specifications
- Material Excellence: Made from premium spring steel (60Si2Mn / 55Si2Mn) for high elasticity and durability.
- 100% NDT Inspection: Every clip is tested using ultrasonic or magnetic particle methods to guarantee no cracks or material flaws.
- Reliable Clamping Force: Consistent clamping force over the entire service life, reducing maintenance frequency.
- Vibration Damping: Elastic design absorbs dynamic loads, protecting both rail and sleeper.
- Easy Installation: Compatible with manual or hydraulic tools; technical support and installation guidance available.
