Anping County Boli Hardware Wiremesh Products Factory, established in 1998 with an annual export value of US$5–10 million, proudly presents our Heat Treated Elastic Rail Clip Fastening (10–15mm diameter). Manufactured from premium spring steel and subjected to a rigorous quenching and tempering process, this rail clip delivers exceptional elasticity, fatigue resistance, and long-term stability under heavy loads. With a Mill Test Report available for every batch, we provide full material traceability and quality assurance for railway projects worldwide.
Our rail fastening system is designed to maintain consistent clamping force, reduce rail vibration, and withstand harsh environmental conditions. As a manufacturer with over two decades of experience, we supply to markets across North America, South America, Europe, Southeast Asia, Africa, Oceania, the Middle East, and more. The following detailed description will help you understand why our product is a reliable choice for your railway infrastructure.
Product Features & Technical Specifications
- Heat Treated Elasticity: The quenching and tempering process ensures optimal hardness (HRC 38–46) and high elasticity, allowing the clip to return to its original shape after repeated deflection.
- Diameter Range 10–15mm: Suitable for various rail types and fastening systems; available in common diameters or customizable upon request.
- Corrosion Resistance: Standard oiled finish protects against rust during storage and transport; optional anti-corrosion coatings (e.g., Dacromet, hot-dip galvanized) can be applied.
- Stable Clamping Force: Designed to maintain a consistent toe load of 8–12 kN (depending on clip size), preventing rail creep and gauge widening.
- Easy Installation & Maintenance: Compatible with standard rail fastening assemblies (e.g., SKL, E-clip styles); can be installed using manual or mechanical tools.
- Mill Test Report Included: Each shipment comes with a certified test report covering chemical composition, mechanical properties, and hardness values.

Frequently Asked Questions
Q1: What material is used for the rail clip?
A1: Our clips are made from high-quality spring steel such as 60Si2Mn or 55Si2Mn, which offers excellent elasticity and fatigue resistance. The exact material can be confirmed in the Mill Test Report.
Q2: Do you provide a Mill Test Report?
A2: Yes, a Mill Test Report is available for every production batch, detailing chemical composition, mechanical properties, and hardness values.
Q3: What is the minimum order quantity (MOQ)?
A3: Our MOQ is typically 500 kg for standard sizes, but we can accommodate smaller trial orders for first-time customers. Please contact us for details.
Q4: Can the diameter be customized?
A4: Yes, we offer diameters from 10 mm to 15 mm, and we can also produce custom diameters within a reasonable range. Please specify your requirements.
Q5: What surface treatment do you apply?
A5: The standard finish is oiled to prevent rust. We also offer options like plain (no coating), Dacromet, or hot-dip galvanized for enhanced corrosion protection.
Q6: Are these clips suitable for high-speed rail?
A6: Our clips are designed for heavy-haul and mainline railways. While they meet general industry standards, we recommend verifying specific requirements for high-speed applications. We can adjust the heat treatment parameters if needed.
Q7: How are the clips packaged for export?
A7: They are typically bundled with steel strapping and wrapped in protective material, then loaded onto pallets or directly into containers. Packaging can be customized per your request.
Q8: What is the lead time for production?
