About Our Rail-to-Sleeper Fastening System
Since 1998, Anping County Boli Hardware Wiremesh Products Factory has been a reliable manufacturer of high-quality rail fastening components. Our Rail-to-Sleeper Fastening System is designed to provide secure and durable fixation between steel rails and concrete or wooden sleepers, ensuring long-term stability for railway tracks. We take pride in offering 100% inspection before shipment and include material certificates according to EN 10204 3.1 with every order, giving you full traceability and confidence in the product quality.
With an annual export value of US$5–10 million and shipments from major Chinese ports (Tianjin, Qingdao, Shanghai, Foshan), we serve markets across North America, South America, Europe, Southeast Asia, Africa, Oceania, and the Middle East. Our fastening system is engineered to meet international standards, offering both performance and cost-effectiveness for railway projects of all scales.
Key Features and Technical Specifications
- High-Strength Materials: Manufactured from premium spring steel (e.g., 60Si2Mn, 55Si2Mn) with a tensile strength of ≥1200 MPa, ensuring excellent fatigue resistance and long service life under heavy loads.
- Precision Manufacturing: CNC machining and heat treatment processes guarantee dimensional accuracy and consistent hardness, reducing installation time and maintenance costs.
- Versatile Surface Options: Available in black oxide, zinc plating, or hot-dip galvanized finishes to meet different corrosion resistance requirements (e.g., coastal or humid environments).
- Drop-In Replacement: Designed to be compatible with standard rail profiles (e.g., UIC54, UIC60, ASCE) and common sleeper types (concrete, wood, composite).
- Complete System Components: Includes rail clips, base plates, sleeper screws, and insulating parts – all matched for optimal clamping force and vibration damping.

Q: Are your fastening systems suitable for both concrete and wooden sleepers?
A: Yes, our system is designed to be compatible with standard concrete, wooden, and composite sleepers. We can also adjust the base plate dimensions for special sleeper designs upon request. -
Q: What is the typical lead time for an order?
A: Lead time depends on the quantity and customization. For standard sizes, we can deliver within 15–25 working days after order confirmation. For large projects, please contact us for a specific schedule. -
Q: Do you offer samples for testing before bulk purchase?
A: Yes, we provide samples free of charge, but the customer pays for shipping. Samples are available within 5–7 days after request. -
Q: Can you customize the surface treatment or other specifications?
A: Absolutely. We offer various surface treatments (zinc, HDG, Dacromet, etc.) and can adjust dimensions, hardness, or clamping force to meet your project requirements. Customization is available upon request. -
Q: How do you ensure the 100% inspection before shipment?
A: Our quality control team checks every component for dimensional accuracy, surface finish, and mechanical performance. We use precision gauge tools and hardness testers. A detailed inspection report can be provided. -
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ for standard fastening systems is 500 sets. For customized items, MOQ may be higher. We can negotiate based on the project. -
Q: Which ports do you ship from, and what is the packaging?
