As a professional manufacturer with over 25 years of experience in railway fastening components, Anping County Boli Hardware Wiremesh Products Factory proudly presents our Heat Treated Elastic Rail Clip with Zinc Plated Finish. Engineered to deliver a reliable 118 MPa tensile strength, this rail clip is designed to secure rails firmly while absorbing dynamic loads and vibrations. Our factory, established in 1998, has exported millions of rail fastening products to markets across North America, South America, Europe, Asia, and Africa, ensuring consistent quality and performance.
This elastic rail clip undergoes a precise heat treatment process to achieve optimal hardness and elasticity, followed by a zinc plating finish that provides excellent corrosion resistance. The result is a durable component suitable for various rail systems, including mainline, heavy-haul, and urban transit networks. The 118 MPa tensile strength ensures the clip maintains its clamping force under extreme conditions, reducing the risk of rail creep and track misalignment.
Below is a detailed breakdown of the product's technical specifications and advantages:
- Material & Treatment: Manufactured from high-quality spring steel, quenched and tempered to achieve a balance of strength and flexibility. The zinc plating (electroplated) provides a uniform protective layer against moisture and salt spray.
- Mechanical Properties: Tensile strength of 118 MPa ensures reliable clamping force. The elastic deflection range is optimized to accommodate rail thermal expansion and contraction without permanent deformation.
- Corrosion Resistance: Zinc plating thickness of 8-12 microns meets standard anti-corrosion requirements (e.g., ASTM B633). Optional hot-dip galvanized finish available upon request for aggressive environments.
- Compatibility: Designed to fit standard rail profiles (e.g., 50kg/m, 60kg/m UIC rails) and can be customized for specific rail types or customer drawings.
- Installation: Easy to install with standard rail fastening systems; can be used with cast or forged base plates and nylon insulators.
- Quality Control: Each batch undergoes tensile strength testing, hardness testing, and dimensional inspection to ensure compliance with international standards.

The heat treatment process not only enhances the clip's strength but also its fatigue life, allowing it to withstand millions of loading cycles without failure. The zinc plating finish acts as a sacrificial coating, protecting the base steel from rust even in humid or coastal environments. This combination of properties makes the clip an excellent choice for railway operators looking to reduce maintenance frequency and extend track service life.

Frequently Asked Questions
-
Q: What is the typical lifespan of this rail clip under normal conditions?
A: Under standard railway operating conditions with proper maintenance, these clips can last 5-8 years or more, depending on traffic load and environmental factors. The zinc plating and heat treatment significantly extend service life compared to untreated clips. -
Q: Can the clip be used with concrete sleepers?
A: Yes, it is compatible with concrete sleepers when used with appropriate base plates, insulators, and pads. We recommend consulting our technical team for specific application requirements. -
Q: Do you offer custom dimensions or different tensile strengths?
A: Yes, we can customize the clip's geometry, dimensions, and mechanical properties (e.g., higher or lower tensile strength) based on your engineering drawings or specifications. Minimum order quantities may apply. -
Q: What is the zinc plating thickness? Is it RoHS compliant?
A: The standard zinc plating thickness is 8-12 microns, and it is RoHS compliant. For thicker coatings (e.g., 15-20 microns), please inquire about availability. -
Q: How are the clips packaged for export?
A: We use woven bags, palletized packaging, or wooden crates depending on the quantity and your preference. Each package is labeled with product details and batch numbers for traceability. -
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 2000 pieces per size, but we can negotiate smaller quantities for sampling or trial orders. Contact us for details. -
Q: Can you provide samples before bulk order?
A: Yes, we offer free samples (buyer pays shipping) for quality evaluation. Samples are typically available within 7-10 days after order confirmation. -
Q: Do you have any quality certifications?
A: Our factory follows strict internal quality control procedures. While we do not claim specific certifications in this listing, we can provide test reports upon request. Our processes are aligned with industry best practices.
