As a trusted manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory specializes in the production of high-performance railway fastening components. Our Rail-to-Sleeper Fastening System with E-Clip Design is engineered to deliver consistent clamping force and long-term reliability under demanding track conditions. With an annual export value exceeding US$5 million, we supply this system to global markets including North America, South America, Europe, and Southeast Asia, ensuring that every set meets rigorous quality standards.
This fastening system is designed to securely anchor rails to concrete or wooden sleepers, providing a robust connection that withstands vertical, lateral, and torsional forces. The E-clip configuration offers excellent fatigue resistance and easy installation, making it a preferred choice for both new track construction and maintenance projects. The 100 kN tension load capacity ensures reliable performance even on heavy-haul and high-speed rail lines.
The 16 mm spring rod is manufactured from premium spring steel, followed by a hot-dip galvanized surface treatment that provides superior corrosion protection. This coating meets industry standards for salt spray resistance, extending service life in harsh environments such as coastal areas and tunnels. Each component is precision-formed to guarantee consistent geometry and clamping force across thousands of installations.
Key Features & Benefits
- E-Clip Design: Ensures elastic clamping with minimal stress concentration, reducing the risk of rail rollover.
- 100 kN Tension Load: Suitable for heavy axle loads and high-speed rail applications.
- 16 mm Spring Rod: Optimized diameter for maximum spring deflection and clamping force retention.
- Hot-Dip Galvanized Surface: Provides long-lasting corrosion resistance, up to 10+ years in normal environments.
- Easy Installation: Pre-assembled components reduce field labor time by up to 30%.
- Low Maintenance: Consistent clamping force reduces the need for periodic retightening.
- Compatibility: Works with standard rail profiles (UIC54, UIC60, BS113A, etc.) and sleeper types.
- Customizable Packing: Available in bulk pallets or kits with fasteners and insulators (optional).

Frequently Asked Questions
-
What is the difference between E-Clip and other clip designs?
E-Clip provides a more elastic clamping force with better fatigue resistance compared to rigid clips. It reduces stress on the rail foot and allows simpler installation. -
Is this system compatible with UIC60 rail?
Yes, our E-Clip fastening system is designed to fit standard rail profiles including UIC54, UIC60, BS113A, and others. Please specify your rail type when ordering. -
Can the hot-dip galvanized coating withstand outdoor exposure?
Absolutely. The coating thickness of ≥85μm provides excellent corrosion protection in most environments, including coastal and industrial areas. For extreme conditions, we can increase the coating thickness upon request. -
What is the lead time for a typical order?
For standard specifications, lead time is 20–30 days after confirmation. Custom orders may require 35–45 days, depending on quantity and complexity. -
Do you provide samples for testing?
Yes, we offer samples (freight collect) for qualified customers. Please contact our sales team with your project details to arrange sample delivery. -
How do you ensure the 100 kN tension load is consistent?
Each spring rod is heat-treated and tested with a precision load cell on a sample basis. We maintain a 100% dimensional inspection for all clips to guarantee clamping force uniformity. -
Can I get a customized packing solution?
Certainly. We can pack the fastening system in bulk, on pallets, or in small kits with screws, nuts, and washers. Please let us know your preferred packing method. -
What is your return policy for defective products?
We offer a one-year warranty against manufacturing defects. If any product fails under normal use, we will replace it free of charge. Our technical support team is available to assist with installation and troubleshooting.
Backed by a factory with 25+ years of experience and annual exports of US$5–10 million, Anping Boli is your reliable partner for railway fastening solutions. Our products are trusted by rail operators in North America, South America, Europe, Africa, and Asia.
