Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a professional manufacturer specializing in railway fastening systems. With over 20 years of experience, we have supplied high-quality elastic rail fastening assemblies to global markets, including North America, South America, Europe, Asia, and Africa. Our Elastic Rail Fastening Assembly with 15mm Thick Rubber Pad and 410 Stainless Steel Clips is designed to provide superior durability, vibration damping, and long-term reliability for railway tracks. This product combines robust engineering with cost-effective materials, ensuring stable rail gauge and reduced maintenance costs.
The assembly consists of a 15mm thick rubber pad that absorbs impact and vibrations, and 410 stainless steel clips that offer excellent corrosion resistance and elastic clamping force. The entire system is engineered to meet the demanding requirements of heavy-haul railways, high-speed lines, and urban transit systems. Below, we break down the key features, technical specifications, and benefits of this product.
Key Features
- High-Quality Rubber Pad: The 15mm thick natural rubber or EPDM pad provides excellent elasticity, reducing noise and vibration by up to 30% compared to standard pads. It also protects the rail base from wear and tear.
- 410 Stainless Steel Clips: Made from grade 410 stainless steel, these clips offer high tensile strength, good corrosion resistance in various climates, and maintain clamping force even under extreme temperature fluctuations.
- Elastic Fastening Design: The clips are designed with a specific spring geometry to ensure consistent rail gauge retention, preventing rail creep and lateral movement.
- Easy Installation: The assembly can be installed quickly using standard tools, reducing labor time and costs. No special equipment is required.
- Low Maintenance: The robust construction and corrosion-resistant materials minimize the need for frequent replacements or adjustments, extending the service life of the track system.
- Customizable Options: Available in different sizes and configurations to match various rail profiles (e.g., 50kg/m, 60kg/m). Custom packaging and marking are also available upon request.

Advantages & Benefits
- Improved Track Stability: The elastic clamping force ensures that the rail remains firmly in place, reducing track geometry deterioration and extending ballast life.
- Noise & Vibration Reduction: The 15mm thick rubber pad effectively dampens vibrations, making it ideal for urban rail systems where noise pollution is a concern.
- Corrosion Resistance: 410 stainless steel clips resist rust and oxidation, even in high-humidity or coastal environments, ensuring long-term performance.
- Cost-Effective: Compared to other high-alloy steel clips, our 410 SS clips offer a balanced combination of strength and affordability, reducing overall project costs.
- Environmental Adaptability: The assembly performs reliably across a wide temperature range, from freezing cold to hot climates, without losing elasticity or clamping force.
- Easy Replacement: Individual components (pad or clip) can be replaced separately without disturbing the entire assembly, simplifying maintenance.

Frequently Asked Questions (FAQ)
Q1: What is the difference between 410 stainless steel and other grades for rail clips?
A1: 410 stainless steel is a martensitic grade that offers high strength and moderate corrosion resistance. It is more cost-effective than 304 or 316 stainless steel while providing sufficient durability for most railway environments. For extremely corrosive conditions, we can supply clips in 304 or 316 upon request.
Q2: Can the rubber pad be customized to a different thickness?
A2: Yes, we can produce rubber pads in thicknesses ranging from 10 mm to 20 mm. Please provide your specific requirements and we will adjust the design accordingly. The standard 15 mm thickness is suitable for most applications.
Q3: What is the expected service life of this fastening assembly?
A3: Under normal operating conditions, the rubber pad can last 5-8 years, and the stainless steel clips can last 10-15 years or more, depending on traffic load, environment, and maintenance. Proper installation and regular inspection will extend the life.
Q4: Do you provide samples for testing before bulk order?
A4: Absolutely. We offer free samples for qualified buyers. You only need to pay the shipping cost. Contact our sales team to arrange sample delivery.
Q5: What certifications do you have for this product?
A5: Our factory follows strict quality control procedures. While we do not hold specific third-party certifications mentioned in the product description, we can provide material test reports and dimensional inspection certificates upon request. We also comply with international standards such as AREMA and UIC as per customer requirements.
Q6: How is the product packaged for export?
A6: Standard packaging is in pallets, wrapped with plastic and steel strapping. Each pallet contains 200-500 sets depending on the size. Custom packaging such as wooden crates, barcodes, or customer logos is available at an additional cost.
Q7: What is the lead time for a typical order?
A7: For a standard 20-foot container (approx. 20,000 sets), the lead time is 15-25 days after receipt of deposit. For smaller orders, it can be as short as 7-10 days. We always try to accommodate urgent requests.
Q8: Can you supply other components of the rail fastening system, like tie plates or insulators?
A8: Yes, we are a comprehensive manufacturer of railway fastening components. In addition to elastic clips and rubber pads, we also produce tie plates, insulators, bolts, and nuts. Please inquire for a complete solution.
