Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer established in 1998 with an annual export value of US$5-10 million, proudly presents our E-type spring clip for concrete sleepers. Manufactured from high-grade 60Si2Mn spring steel and fully hot dip galvanized, this clip meets the rigorous UIC 864 standard to ensure reliable fastening in railway systems. Our experienced team combines over two decades of metalworking expertise with advanced production lines to deliver consistent quality and performance. Whether for new rail construction or maintenance, this spring clip offers superior elasticity, corrosion resistance, and long service life.
Key Features & Technical Specifications
- Material Excellence: 60Si2Mn spring steel provides high yield strength and excellent fatigue resistance, ensuring the clip maintains clamping force even under dynamic loads.
- Hot Dip Galvanized Protection: A thick zinc coating (≥85 μm) applied by hot dipping offers outstanding corrosion resistance for tracks exposed to harsh environments, including rain, snow, and coastal salt spray.
- UIC 864 Compliance: Manufactured strictly in accordance with UIC 864 leaflet, guaranteeing dimensional accuracy, elastic properties, and interchangeability with other UIC-compliant components.
- E-Type Design: The unique E-shaped geometry optimizes the distribution of clamping force on the concrete sleeper, reducing stress concentration and preventing loosening.
- Easy Installation: The clip is designed for quick mounting and dismounting with standard tools, reducing labor time during track laying or maintenance.
- Long Service Life: Combined material durability and galvanizing yield a service life of 10–15 years under normal operating conditions, lowering total lifecycle costs.

Benefits for Your Railway Project: By choosing our E-type spring clip, you gain a reliable fastening solution that reduces maintenance frequency, improves track stability, and meets international railway standards. The 60Si2Mn steel ensures the clip retains its elasticity after millions of load cycles, while the hot dip galvanizing provides a barrier against oxidation for decades. For concrete sleeper systems, the E-type clip offers a proven balance of flexibility and strength, accommodating slight temperature expansion without losing grip.
Frequently Asked Questions
-
Q: What is the difference between E-type and other spring clips?
A: The E-type clip has a distinctive shape that distributes clamping force more evenly across the concrete sleeper, reducing stress on the rail foot. It is specifically designed for heavy-duty mainline tracks and high-speed railways, offering better fatigue life than traditional omega or K-type clips. -
Q: Can you customize the clip dimensions?
A: Yes, we can customize the clip's dimensions (e.g., wire diameter, arm length) to match specific sleeper designs or rail profiles, provided they remain within the UIC 864 tolerance range. Please contact our technical team with your requirements. -
Q: How long does the hot dip galvanizing last?
A: Under normal outdoor conditions, the hot dip galvanized coating (≥85 μm) typically lasts 10–15 years before significant corrosion appears. In aggressive environments (e.g., coastal, industrial), the lifespan may be reduced; we recommend periodic inspection. -
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 500 pieces for new customers. For repeat orders or bulk quantities, we can negotiate lower MOQs. Contact us for details. -
Q: Do you provide samples for testing?
A: Yes, we offer samples (cost of sample and shipping) for evaluation. The sample fee will be deducted from your first purchase order. Samples are available within 5–7 working days. -
Q: Is this clip compatible with all concrete sleeper types?
A: The clip is designed for concrete sleepers that meet UIC 864 specifications. For non-standard sleepers, we recommend verifying the shoulder geometry and recess dimensions. Our engineers can provide compatibility guidance. -
Q: How do you ensure quality consistency?
A: We implement a strict quality control system from raw material incoming inspection (chemical composition, hardness) to in-process checks (dimensional accuracy, heat treatment parameters) and final testing (fatigue test, galvanizing thickness). Each batch is traceable. -
Q: What are the payment terms?
A: Common payment terms are T/T (30% deposit, 70% before shipment) or L/C at sight. For long-term partnerships, other terms may be negotiable.
