Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a professional manufacturer specializing in railway fastening systems. With annual export value exceeding US$5 million, we supply high-quality Elastic Rail Clips designed for heavy haul railway applications. Our 14mm hardened surface rail clip made from 60Si2Mn spring steel delivers exceptional durability, fatigue resistance, and reliable clamping force, ensuring safe and stable track performance under extreme loads. Trusted by clients across North America, Europe, Asia, and beyond, our products are your ideal choice for demanding railway infrastructure.
This elastic rail clip is engineered to meet the rigorous demands of heavy haul railways, where continuous high axle loads and frequent traffic require components with superior strength and elasticity. The 60Si2Mn spring steel provides excellent resilience, while the hardened surface enhances wear resistance and extends service life. Each clip is precisely manufactured to a 14mm diameter, ensuring consistent fit and clamping force. Whether for new track construction or maintenance replacement, these clips offer reliable performance in diverse climates and operating conditions.
Key Features & Technical Specifications
- High-Quality Material: Made from 60Si2Mn spring steel, known for its excellent fatigue strength and elastic limit.
- Hardened Surface: Surface hardness is enhanced through heat treatment (HRC 40-48), improving wear resistance and longevity.
- Precise Dimensions: 14mm diameter ensures consistent clamping force and compatibility with standard rail fastening systems.
- Heavy Haul Capability: Designed to withstand high axle loads (up to 35 tons) and frequent dynamic stresses.
- Corrosion Resistance: Optional surface coating (e.g., black oxide, zinc plating) available upon request for harsh environments.
- Easy Installation: Clip design allows for quick and secure mounting with standard tools, reducing labor time.
- Rigorous Quality Control: Each batch undergoes hardness testing, dimensional inspection, and fatigue testing to ensure consistent performance.

Advantages for Your Project
- Extended Service Life: The hardened surface reduces wear, minimizing replacement frequency and lowering maintenance costs.
- Reliable Clamping Force: Consistent elastic performance ensures proper rail gauge retention under heavy loads, improving safety.
- Cost-Effective: Durable material and optimized design provide excellent value for money compared to lower-grade alternatives.
- Global Compatibility: Dimensions meet common international railway standards; can be customized to match specific rail profiles.
- Fast Delivery: With our factory located in Hengshui, Hebei, and multiple ports of shipment (Tianjin, Qingdao, Shanghai, Foshan), we ensure timely delivery worldwide.
Our elastic rail clips have been tested under simulated heavy haul conditions, demonstrating excellent fatigue life exceeding 3 million cycles without failure. The 60Si2Mn material, combined with controlled heat treatment, delivers a balanced combination of strength and ductility, absorbing vibrations and impact loads effectively. This makes them particularly suitable for high-density freight corridors and mining railways where downtime is costly.
