Since 1998, Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer of railway fastening components. Our 2-type Elastic Rail Clip is specifically engineered for high-speed rail turnout systems, where precision and reliability are non-negotiable. This clip plays a critical role in maintaining gauge stability, ensuring that rails remain securely aligned even under dynamic loads. With decades of experience in metal forming and surface treatment, we deliver a product that meets the rigorous demands of modern rail infrastructure.
The 2-type elastic rail clip is designed to provide consistent clamping force while allowing for necessary thermal expansion and vibration absorption. It is manufactured from high-grade spring steel, heat-treated to achieve optimal hardness and elasticity. Each clip undergoes strict quality control to guarantee dimensional accuracy and long-term performance. Whether used in new installations or maintenance projects, this clip offers a cost-effective solution for improving track stability and reducing maintenance frequency.
Key Features & Benefits
- Superior Elasticity: The clip's unique shape and material composition provide excellent elastic recovery, ensuring stable clamping force over time.
- Gauge Stability: Designed to resist lateral rail movement, maintaining proper track gauge even under high-speed and heavy-load conditions.
- Fatigue Resistance: Advanced heat treatment process extends the service life of the clip, reducing replacement frequency.
- Easy Installation: Compatible with standard turnout fastening systems, allowing quick and secure installation without special tools.
- Corrosion Protection: Available with black oxide or zinc plating to resist rust in various environments.
- Certified Quality: Manufactured in accordance with industry standards such as TB/T 3065-2002, ensuring consistent performance.

Detailed Product Description
The 2-type elastic rail clip is a key component in high-speed rail turnout systems. Its primary function is to secure the rail to the sleeper while maintaining precise gauge alignment. Unlike traditional rigid clips, the elastic design allows the clip to absorb dynamic forces from passing trains, reducing stress on the rail and fastening assembly. This results in enhanced track stability, reduced noise, and lower maintenance costs over the lifecycle of the system.
Manufactured using advanced precision stamping and heat treatment processes, each clip exhibits consistent mechanical properties. The material is carefully selected for high yield strength and fatigue life, ensuring that the clip can withstand millions of loading cycles without permanent deformation. Dimensional tolerances are held to tight limits (typically ±0.5 mm) to guarantee compatibility with standard rail profiles and baseplates.
The clip is available in various surface finishes to suit different environmental conditions. For indoor or dry applications, black oxide provides adequate protection. For outdoor or coastal areas, zinc plating offers superior corrosion resistance. Custom coatings such as Dacromet or hot-dip galvanizing can also be applied upon request. The product is suitable for use in both new construction and retrofit projects, compatible with most common turnout systems used in high-speed rail networks worldwide.
One of the major advantages of the 2-type clip is its ease of installation and removal. The clip can be installed using standard rail fastening tools, and its design allows for quick inspection and replacement when necessary. This reduces downtime during track maintenance and improves overall operational efficiency. Additionally, the clip's elastic nature helps maintain consistent clamping force even as the rail expands or contracts due to temperature changes, further contributing to gauge stability.
We understand that every rail project has unique requirements. Therefore, we offer customization options for dimensions, material grade, hardness, and surface treatment. Our engineering team can work with you to develop a clip that meets your specific performance criteria. With a minimum order quantity (MOQ) as low as 1,000 pieces, we can accommodate both small trials and large-scale orders.
