We are proud to present our Fully Assembled Elastic Rail Fastening System with 20kN Preload, 100mm Rail Base Width, manufactured by Anping County Boli Hardware Wiremesh Products Factory — a trusted manufacturer established in 1998 with over two decades of experience in railway hardware. Our annual export value ranges from US$5 Million to US$10 Million, serving markets across North America, South America, Europe, Asia, Africa, and Oceania. This fastening system is designed to deliver consistent clamping force, reduce maintenance, and ensure long-term track stability, making it an ideal choice for heavy-haul and high-speed rail applications.
The system is fully assembled at the factory, eliminating on-site assembly errors and saving installation time. With a precise 20kN preload and compatibility with 100mm rail base width, it provides optimal elastic performance, dampening vibrations and resisting rail creep. All components are manufactured from high-strength steel and treated with anti-corrosion coatings to withstand harsh environments.
Key Features & Technical Specifications
- High Preload Accuracy: Factory-set 20kN preload ensures uniform clamping force across all fasteners, reducing track gauge deviation.
- 100mm Rail Base Width Compatibility: Designed for standard UIC 60 / 54 / 50 rails with 100mm base width, also available for other widths upon request.
- Elastic Clip Design: Spring steel clips with optimized geometry provide long fatigue life and consistent toe load.
- Corrosion Protection: Hot-dip galvanized or Dacromet coating available, tested in salt spray over 500 hours.
- Easy Installation: Pre-assembled with baseplate, insulator, clip, and bolt – ready to install directly on sleepers.
- Low Maintenance: Elastic design reduces loosening, minimizing inspection and re-tightening frequency.
- Vibration Damping: Rubber pad included (optional) to absorb dynamic loads and protect sleeper surface.
- Temperature Range: Suitable for -40°C to +60°C operating conditions.

Why Choose Our Fully Assembled System? Compared to traditional loose components, our pre-assembled design reduces installation time by up to 40% and eliminates the risk of missing parts or incorrect assembly. The 20kN preload ensures consistent performance across the entire track, which is critical for maintaining gauge and reducing wheel-rail wear. Over 15 years of production experience ensures strict quality control at every stage.
Application Scenarios
- Mainline railways (heavy haul, high-speed up to 200 km/h)
- Metro and urban transit systems
- Industrial railways and mining tracks
- Port and container yard rail systems
- Turnout and crossing areas

Frequently Asked Questions
-
Q: What rail profiles are compatible with your 100mm base width system?
A: Our system is compatible with UIC 60 (100mm base), UIC 54, and other rails with the same base width. For rails with different base widths, we can customize the baseplate. -
Q: Is the preload adjustable in the field?
A: The preload is factory-set to 20kN and is not intended for field adjustment. However, we can produce variants with different preload values (e.g., 15kN, 25kN) upon request. -
Q: What is the typical lifespan of the elastic clip?
A: Under normal operating conditions, the clip can last over 10 years with proper maintenance. Fatigue testing shows no failure after 3 million cycles. -
Q: Do you provide installation instructions or training?
A: Yes, we offer detailed installation manuals and can arrange on-site technical support for large orders. -
Q: What certifications do your products have?
A: Our products are manufactured according to international standards such as UIC 861-1 and AREMA. Specific certifications can be provided upon request based on your market requirements. -
Q: Can you supply samples before mass production?
A: Absolutely. We can provide samples for evaluation; sample freight is negotiable. -
Q: What is the minimum order quantity (MOQ)?
A: For standard products, MOQ is usually 500 sets. For customized products, MOQ may vary. -
Q: How do you ensure the consistent quality of each batch?
A: We follow a strict ISO 9001-based quality management system. Each batch undergoes chemical analysis, hardness test, dimensional inspection, and preload verification.
