Anping County Boli Hardware Wiremesh Products Factory proudly presents our E-type Elastic Rail Clip, specifically designed for 50kg/m rail with a precise 70mm length. Manufactured from premium Spring Steel Grade 60Si2Mn and finished with shot blasting, this clip delivers exceptional elasticity and fatigue resistance for reliable railway fastening. As a trusted manufacturer since 1998, we combine decades of metallurgical expertise with advanced production techniques to ensure consistent quality and long service life, making your rail infrastructure safer and more durable.
Our E-type elastic rail clip is engineered to provide optimal clamping force while maintaining flexibility under dynamic loads. The 60Si2Mn spring steel offers excellent hardness and toughness, while the shot blasting process removes surface impurities and introduces compressive stresses, significantly enhancing corrosion resistance and fatigue strength. Whether for mainline tracks, sidings, or industrial railways, this clip meets the rigorous demands of modern rail systems.
Key Features & Technical Specifications
- Material Excellence: Grade 60Si2Mn spring steel (equivalent to 60Si2CrVA or similar) ensures high yield strength and elastic limit, capable of withstanding repetitive stress cycles without plastic deformation.
- Precision Dimensions: 70mm length tailored for 50kg/m rail profiles, with tight tolerances (±0.5mm) to guarantee consistent clamping force across all installations.
- Shot Blasted Surface: Uniform shot peening removes mill scale, burrs, and micro-cracks, improving surface finish and extending service life by 30% compared to untreated clips.
- E-type Geometry: Optimized shape provides a balance of flexibility and strength, reducing the risk of rail rollover and ensuring secure fastening even under high lateral forces.
- Anti-Corrosion Option: Available with additional coatings (e.g., zinc plating, Dacromet) upon request for harsh environments such as coastal or humid regions.
- Compatibility: Works with standard rail clips, insulators, and baseplates used in 50kg/m rail systems, fully interchangeable with global designs.

Frequently Asked Questions
-
Q: What is the difference between E-type and other rail clip types?
A: E-type clips are designed for 50kg/m rail and offer a balanced profile with moderate elasticity, making them suitable for both mainline and secondary tracks. They are often preferred for their reliable clamping force and ease of installation. -
Q: Can this clip be used for rails of other weights, like 60kg/m?
A: No, this specific E-type clip is engineered for 50kg/m rail. Using it on different rail profiles may result in improper clamping or reduced performance. Custom sizes are available upon request for other rail weights. -
Q: Is the shot blasting process sufficient for corrosion protection?
A: Shot blasting primarily removes surface impurities and introduces compressive stress, which improves fatigue life but does not provide long-term corrosion protection. For exposed environments, we recommend additional coatings such as zinc plating or Dacromet, which are available as optional treatments. -
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 10,000 pieces, but we can accommodate smaller trial orders for new customers. Please contact our sales team for details. -
Q: How do you ensure consistent quality across production batches?
A: We follow strict incoming material inspection, in-process dimensional checks, and final testing including hardness, tensile strength, and fatigue tests. Random samples from each batch are retained for traceability. -
Q: Can you provide samples for testing?
A: Yes, we offer free samples (freight collect) for qualified customers. Samples are typically shipped within 5-7 working days after order confirmation. -
Q: What is the typical lead time for bulk orders?
A: Lead time depends on quantity. For 100,000 pieces, it is usually 20-25 days after receipt of deposit. We can expedite for urgent projects upon request. -
Q: Do you have any certifications for quality management?
A: We operate according to internal quality standards that meet industry requirements. Specific certifications can be discussed based on project needs – please inquire with our sales team for more information.
