Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer of railway fastening components since 1998. Our Rail-to-Sleeper Fastening System made from 40Cr Alloy Steel and subjected to quenching and tempering is engineered for optimal performance on 60E1 rail profiles with a 12mm clip wire diameter. This system ensures reliable rail fixation, reduces maintenance needs, and extends the service life of your railway infrastructure. With an annual export value of US$5 million to US$10 million, we supply customers across North America, South America, Europe, Asia, Africa, and Oceania, delivering consistent quality and competitive pricing.
Our fastening system is designed to meet the rigorous demands of modern railway operations. The use of 40Cr alloy steel combined with precise heat treatment provides exceptional strength, fatigue resistance, and elasticity. The 12mm clip wire diameter ensures a secure grip on the rail while allowing for necessary thermal expansion and contraction. Whether you are building new tracks or upgrading existing ones, this system offers a dependable solution for both heavy-haul and high-speed rail lines.
Product Features & Technical Specifications
- Material: 40Cr Alloy Steel – high hardenability, excellent wear resistance, and good toughness after quenching and tempering.
- Heat Treatment: Quenched and Tempered – achieves consistent hardness (HRC 38-45) and improved ductility, reducing the risk of brittle fracture.
- Rail Profile Compatibility: 60E1 (UIC60) – widely used in mainline, heavy-haul, and high-speed railways.
- Clip Wire Diameter: 12mm – provides optimal clamping force while maintaining elasticity.
- Surface Finish: Oiled or black oxide (optional) – corrosion protection for extended service life.
- Design: Standard elastic clip design with easy installation and removal.
- Application: Suitable for concrete sleepers, wooden sleepers, and steel sleepers with appropriate baseplates.
- Customization: Available upon request – dimensions, surface treatment, and packaging can be tailored to specific project requirements.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between this 40Cr alloy steel clip and standard carbon steel clips?
A: 40Cr alloy steel offers higher strength, better hardenability, and improved fatigue resistance compared to common carbon steels like 60Si2Mn or 55Cr3. The quenching and tempering process further enhances toughness, making it suitable for heavy-duty railway applications. -
Q: Can this fastening system be used with other rail profiles besides 60E1?
A: This system is specifically designed for 60E1 (UIC60) rail profile. For other profiles such as 50E1, 54E1, or 136RE, we recommend contacting us for customized clips or baseplates. -
Q: What is the expected service life of these clips under normal conditions?
A: Under typical mainline traffic with proper maintenance, the clips can last 10–15 years or more. Actual life depends on factors like traffic density, climate, and track maintenance practices. -
Q: Do you provide samples for testing before bulk order?
A: Yes, we offer sample orders. Please contact our sales team for sample availability and shipping costs. We can provide small quantities for evaluation. -
Q: What surface finishes are available? Which one do you recommend for coastal or humid environments?
A: Standard finishes include oiled (temporary protection) and black oxide. For coastal or high-humidity areas, we recommend black oxide or a custom zinc-rich coating. Please discuss your environmental conditions with us for the best option. -
Q: What is the minimum order quantity (MOQ)?
A: MOQ for standard clips is typically 5,000 pieces. For customized items, the MOQ may be higher. Please inquire with our sales team for specific requirements. -
Q: How do you ensure the quality of the clips?
A: We perform in-process inspections and final testing including hardness, tensile strength, and dimensional checks. Each batch is accompanied by a test certificate. We also offer third-party inspection upon request. -
Q: What is the packaging method for export?
A: Clips are packed in woven bags or palletized with steel straps, then loaded into containers. We can also provide customized packaging according to your specifications (e.g., smaller cartons for distribution).
