Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a professional manufacturer specializing in railway fastening components. Our Spring Steel Rail Clip is engineered to deliver reliable performance in demanding rail environments. With over 20 years of manufacturing experience and an annual export value of US$5–10 million, we supply to global markets including North America, Europe, Southeast Asia, and Africa. This heat-treated rail clip offers a precise hardness of 40–45 HRC, ensuring excellent elasticity and fatigue resistance for long-lasting rail fastening solutions.
Our rail clips are made from high-grade spring steel (60Si2Mn or equivalent), processed through a strict quenching and tempering procedure to achieve the specified hardness range. The 40–45 HRC hardness provides the optimal balance between strength and ductility, allowing the clip to withstand repeated loading cycles without permanent deformation. This product is an essential component in modern railway fastening systems, used to secure rails to sleepers and maintain track gauge stability.
- Material: Premium spring steel (60Si2Mn / 55Si2Mn) for high yield strength and elasticity.
- Heat Treatment: Quenched and tempered to achieve a uniform hardness of 40–45 HRC across the entire clip.
- Durability: Excellent fatigue life – tested over 3 million cycles without failure (data available upon request).
- Corrosion Resistance: Available with black oxide finish or other anti-corrosion coatings as required.
- Compatibility: Designed to fit standard rail bases (e.g., UIC60, 50kg, 54kg, etc.) and can be customized for special profiles.
- Precision Manufacturing: CNC bending and forming ensure consistent dimensions within ±0.5mm tolerance.
- Easy Installation: Lightweight design with simple insertion mechanism reduces labor time on site.
- Cost-Effective: Long service life lowers replacement frequency and maintenance costs.

The Spring Steel Rail Clip is a critical component in the railway fastening system. It provides the clamping force necessary to keep the rail firmly attached to the sleeper while allowing for thermal expansion and vibration damping. Our heat-treated clips are designed to maintain consistent clamping force over time, reducing the risk of loosening and track misalignment. The hardness range of 40–45 HRC is carefully selected to balance wear resistance and flexibility, ensuring the clip can absorb dynamic loads without cracking or permanent set.
Key Benefits for Customers:
- Improved track safety and stability due to consistent clamping force.
- Reduced maintenance intervals – clips last longer than standard untreated versions.
- Compatible with various rail types and sleeper designs (concrete, wood, steel).
- Customizable dimensions and shapes to meet specific project requirements.
- Reliable supply from a manufacturer with 25+ years of export experience.

Frequently Asked Questions
Q1: What material is the rail clip made of?
A: Our rail clips are made from high-quality spring steel, typically 60Si2Mn or 55Si2Mn, which offers excellent elasticity and fatigue resistance. We can also supply alternative grades upon request.
Q2: What is the hardness range, and why is it important?
A: The hardness is 40–45 HRC. This range provides an optimal balance between strength and ductility, ensuring the clip can withstand repeated loading without cracking or losing its clamping force.
Q3: Can you customize the clip dimensions or shape?
A: Yes, we offer customization. We can produce clips according to your drawings or samples, including different types (SKL, CK, PR) and sizes. Please provide your requirements for a quotation.
Q4: What is the typical lead time for an order?
A: For standard sizes, lead time is usually 15–25 days after order confirmation. For custom items, it may be 25–35 days depending on complexity. We can expedite urgent orders upon negotiation.
Q5: Do you provide samples for testing?
A: Yes, we offer free samples for existing designs. The buyer pays shipping costs. For custom samples, there may be a mold fee, which is refundable with bulk orders.
Q6: Which rail types are these clips compatible with?
A: Our clips are designed to fit standard rail profiles such as UIC60, 50kg, 54kg, 60kg, and others. We can also adjust the design to match specific rail base dimensions.
Q7: How is the surface treated to prevent corrosion?
A: Standard treatment is black oxide (blackening) and oiling. Other options include zinc plating, hot-dip galvanizing, or Dacromet coating, depending on your environmental requirements.
Q8: What quality control measures do you have in place?
A: We have a dedicated QC team that inspects raw materials, in-process parameters (hardness, dimensions), and final products. Each batch is tested for hardness and mechanical properties. Test reports are available upon request.
