Welcome to the reliable rail fastening solution from Anping County Boli Hardware Wiremesh Products Factory. As a seasoned manufacturer with over 25 years of expertise, we present our Rail-to-Sleeper Fastening System specifically engineered for tunnel and bridge construction in demanding environments. This system features a compact design that saves space while ensuring robust holding power, and its corrosion resistance makes it ideal for humid and wet conditions. Whether you're building a subway tunnel or a coastal railway bridge, our fastening system delivers long-term stability and low maintenance, helping you reduce lifecycle costs.
Our product stands out due to its precision engineering and adaptability. The fastening system is designed to accommodate different rail profiles and sleeper types, providing a secure clamp that withstands dynamic loads and vibrations. The compact design also facilitates easier installation in confined spaces, such as tunnel bores and bridge decks, where accessibility is limited. Moreover, the anti-corrosion treatment ensures that the system remains functional in high-humidity environments, preventing rust and degradation over time.
Key Features & Benefits
- Compact Design – Optimized for tight spaces in tunnels and bridges, reducing clearance requirements and simplifying installation.
- Corrosion Resistance – Treated with hot-dip galvanizing or Dacromet coating, effectively resisting rust in humid, salty, or chemically aggressive environments.
- High Holding Strength – Engineered to maintain consistent clamping force, reducing rail movement and ensuring track alignment.
- Easy Installation & Maintenance – Modular components with pre-assembled parts speed up on-site work; no special tools required.
- Vibration Damping – Integrated elastic pads absorb shock and noise, improving passenger comfort and protecting infrastructure.
- Long Service Life – Durable materials and surface treatment extend service intervals, lowering overall operational costs.

Advantages for Your Project
In tunnel construction, space is at a premium. Our compact fastener system allows for a lower track profile, which can reduce the overall tunnel diameter and save excavation costs. For bridges, the corrosion resistance is critical because of exposure to rain, humidity, and sometimes de-icing salts. The system’s robust design also minimizes the need for frequent inspections and replacements, which is especially valuable in hard-to-reach bridge sections. Furthermore, the fasteners are compatible with standard track maintenance equipment, ensuring seamless integration into your existing operations.

Frequently Asked Questions
-
Q: What is the typical lead time for this fastening system?
A: For standard configurations, our lead time is 15–20 working days after order confirmation. Custom orders may require additional time; please contact us for details. -
Q: Can you provide samples for testing before bulk order?
A: Yes, samples are available. We can produce a few sets for your evaluation. The sample cost and shipping are negotiable. -
Q: Is this system compatible with existing rail profiles of 60kg/m?
A: Absolutely. Our fastening system is designed to fit 43kg/m, 50kg/m, and 60kg/m rails. We also offer customization for other profiles. -
Q: How do you ensure corrosion resistance for humid environments?
A: We apply hot-dip galvanizing (thickness ≥85μm) or Dacromet coating, both of which provide excellent protection in high-humidity and corrosive conditions. Specific treatments can be tailored upon request. -
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ is typically 500 sets. However, for first-time cooperation or trial orders, we may be flexible. Please discuss with our sales team. -
Q: Do you provide installation instructions or technical support?
A: Yes, we include detailed installation drawings and guidelines with each shipment. Additionally, our engineers can offer online support or on-site guidance if needed. -
Q: Can this system be used in curved track sections?
A: Yes, the design accounts for curves. The clamping force and spacing can be adjusted to suit the curvature radius. Please provide your specific requirements. -
Q: How does the compact design benefit tunnel construction?
A: The low-profile fasteners reduce the required track height, allowing smaller tunnel cross-sections, which lowers excavation costs and speeds up construction.
