Product Advantages
- Superior Elasticity & Fatigue Resistance: The specially designed W-shape and spring steel composition ensure excellent energy absorption, reducing the risk of rail displacement and improving passenger comfort.
- Consistent Clamping Force: Maintains stable rail gauge and prevents loosening over time, even under high-frequency dynamic loads typical of high-speed trains.
- Corrosion & Wear Protection: Available with black oxide or oil coating, providing effective resistance against rust and environmental degradation.
- Easy Installation & Maintenance: Lightweight design (approx. 0.8 kg per piece) and compatibility with standard rail fastening systems reduce installation time and labor costs.
- Customizable Hardness & Coating: We can adjust the heat treatment and surface finish to meet specific customer requirements, including different hardness levels or anti-corrosion standards.
- Rigorous Quality Control: Each clip undergoes dimensional inspection, hardness testing, and fatigue testing to ensure consistent performance.

Frequently Asked Questions (FAQ)
-
What material is used for your W-Type elastic rail clip?
We use high-quality spring steel, typically grade 60Si2Mn or equivalent, which provides excellent elasticity and durability. -
Is the 14mm diameter suitable for all high-speed rail systems?
The 14mm diameter is a common specification for many standard high-speed rail fastening systems. However, we can customize the diameter and other dimensions to match your specific rail profile and sleeper design. -
What surface treatments are available?
Standard options include black oxide coating and oil finish. We also offer customized coatings such as zinc plating, Dacromet, or organic coatings upon request to meet specific corrosion resistance requirements. -
Do you provide samples for testing?
Yes, we offer free samples for evaluation (shipping costs may apply). Please contact us with your project details, and we will arrange sample shipment. -
What is the typical lead time for bulk orders?
Lead time depends on order quantity. For a standard container quantity (e.g., 20,000 pieces), production usually takes 20–30 days after sample approval and deposit receipt. -
Can you provide test reports or certifications for the rail clips?
We provide in-house inspection reports including dimensional, hardness, and tensile tests. If you require third-party testing or specific certifications, we can arrange them at an additional cost. Please note that our products are designed to meet international railway standards. -
How do you ensure consistent quality across batches?
We follow strict quality control procedures: incoming material inspection, in-process checks, and final inspection before shipment. Each batch is traceable, and we maintain records for at least 3 years. -
What is the minimum order quantity (MOQ)?
Our MOQ is 1,000 pieces for standard size. For customized sizes, MOQ may be higher. We are flexible and can discuss based on your requirements.
