Product Overview
As a professional manufacturer established in 1998, Anping County Boli Hardware Wiremesh Products Factory specializes in producing high-quality railway fastening components. Our E-Shaped Elastic Rail Clip Fastening, Grade 8.8, with Anti-Corrosion Coating, is engineered to deliver reliable performance in demanding rail environments. With an annual export value of US$5–10 million and global shipping from Tianjin, Qingdao, Shanghai, and Foshan, we ensure that every clip meets rigorous quality standards. This product combines excellent elasticity, high strength, and superior corrosion resistance to extend service life and reduce maintenance costs.
Key Features & Technical Specifications
- E-Shaped Elastic Design – Provides consistent clamping force and absorbs vibrations, ensuring stable rail positioning and reducing track irregularities.
- Grade 8.8 Strength – Manufactured from high-quality spring steel (e.g., 60Si2Mn) with heat treatment to achieve 8.8 grade mechanical properties, including tensile strength ≥ 800 MPa and yield strength ≥ 640 MPa.
- Anti-Corrosion Coating – Available with black oxide, zinc plating, or Dacromet coating to withstand harsh environments, including humidity, salt spray, and chemical exposure. Tested per ASTM B117 for salt spray resistance (up to 200 hours upon request).
- Precise Dimensions – Each clip is manufactured to tight tolerances (e.g., ±0.5 mm) for easy installation and compatibility with standard rail bases and insulators.
- Low Maintenance – The elastic design minimizes permanent deformation, and the coating reduces rust and wear, lowering total lifecycle costs.
- Wide Application – Suitable for railway main lines, sidings, mines, ports, and light rail systems. Compatible with UIC 54, UIC 60, and other rail profiles.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between Grade 8.8 and other grades?
A: Grade 8.8 indicates a minimum tensile strength of 800 MPa and yield strength of 640 MPa, providing higher load capacity than lower grades like 4.8 or 6.8. This makes the clip suitable for heavy-duty railway applications. -
Q: Can the coating be customized for extremely corrosive environments?
A: Yes. We offer Dacromet coating and hot-dip galvanizing options for enhanced corrosion resistance. Please specify your requirements (e.g., salt spray test hours) when ordering. -
Q: Are these clips compatible with standard rail insulators?
A: Yes, our E-shaped clips are designed to fit standard rail insulators (e.g., nylon or polyurethane) used in common rail fastening systems. We can provide technical drawings for verification. -
Q: What is the typical lead time for bulk orders?
A: For standard sizes, lead time is 15–25 days after order confirmation. For custom specifications, please allow 20–30 days. We ship from Tianjin, Qingdao, Shanghai, or Foshan ports. -
Q: Do you provide samples for testing?
A: Yes, we offer free samples for quality evaluation. The buyer only needs to cover shipping costs. Contact our sales team to request samples. -
Q: How do you ensure the quality of the clips?
A: We perform 100% dimensional inspection, hardness testing, and coating thickness measurement. Random samples are tested for clamping force and salt spray resistance. A quality certificate is provided with each shipment. -
Q: Can I get a customized packaging?
A: Yes, packaging can be customized (e.g., pallet, carton, or bulk packing) according to your requirements. We also support OEM/ODM labels. -
Q: What rail profiles are compatible with this clip?
A: The clip is compatible with UIC 54, UIC 60, and similar rail profiles. For other profiles, we can adjust the dimensions. Please provide rail specifications for customization.
