Introducing the Black Oxide Coated 2-type Elastic Rail Clip – a precision-engineered fastening component designed for demanding railway applications. Manufactured by Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 with annual export values exceeding US$5 million, this rail clip combines robust construction with advanced surface treatment. The 13mm×13mm cross section ensures reliable clamping force, while the black oxide coating provides excellent corrosion resistance and reduces friction during installation. Our factory adheres to ISO 9001 quality management standards, ensuring consistent product performance across every shipment.
This elastic rail clip is specifically designed as a Type 2 (2-type) component, widely used in railway track systems to secure rails to sleepers or base plates. The black oxide finish not only enhances durability but also offers a matte appearance that reduces glare for maintenance crews. With a cross-section of 13mm×13mm, it balances flexibility and strength, making it suitable for both heavy-haul and high-speed rail lines. Below we detail the key features, technical specifications, and benefits that make our rail clip a preferred choice for rail contractors and infrastructure companies worldwide.
Key Features & Technical Specifications
- Material Excellence: Manufactured from high-quality spring steel (e.g., 60Si2Mn) with controlled hardness (HRC 40-48) to achieve optimal elasticity and fatigue resistance.
- Black Oxide Coating: A controlled oxidation process creates a uniform magnetite layer (Fe₃O₄) that protects against corrosion and wear, with a typical thickness of 0.5-1.5 μm.
- Precision Dimensions: 13mm × 13mm cross section with tight tolerances (±0.5mm) to ensure consistent clamping force and compatibility with standard rail clip slots.
- Type 2 Geometry: Designed according to industry-standard Type 2 profile, featuring a specific shape that provides optimal toe load and deflection characteristics.
- ISO 9001 Compliant Factory: Our production facility follows strict quality control procedures, from raw material inspection to final packaging, ensuring each clip meets international standards.
- Customizable Options: Available in various lengths, batch sizes, and packaging configurations (pallets, wooden cases, cartons) to suit your logistics requirements.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between a Type 2 elastic rail clip and other types?
A: The Type 2 clip has a specific geometry that provides a balanced toe load and deflection, making it suitable for medium to heavy rail applications. It is commonly used in mainline tracks and turnout systems. Other types (e.g., Type 1, Type 3) may have different clamping forces or installation methods. -
Q: How does the black oxide coating improve performance?
A: Black oxide coating provides a protective layer that resists corrosion and reduces friction, preventing galling during installation. It also has a matte appearance that minimizes glare and improves visual inspection. The coating does not significantly affect the clip's mechanical properties. -
Q: Can you supply clips with a different cross-section, such as 12mm×12mm or 14mm×14mm?
A: Yes, we can customize the cross-section dimensions according to your requirements. However, the 13mm×13mm size is standard and immediately available. Please contact our sales team with your specific needs. -
Q: What is the typical lead time for bulk orders?
A: For standard 13mm×13mm 2-type clips, lead time is approximately 15-25 days after order confirmation, depending on quantity. For customized orders, it may be 30-45 days. We recommend placing orders well in advance for large projects. -
Q: Do you provide samples for testing before bulk purchase?
A: Yes, we offer free samples for qualified buyers. You only need to cover the shipping cost. Samples are typically shipped within 5 working days. -
Q: How do you ensure the clips meet international quality standards?
A: Our factory operates under ISO 9001 quality management system. We conduct incoming material inspection, in-process checks, and final testing (dimensions, hardness, surface finish) for every batch. A test certificate can be provided upon request. -
Q: What is the packaging method for export?
A: Standard packaging includes steel pallets with shrink wrap, or wooden cases for sea freight. We also offer custom packaging with labels as per your instructions. All packaging is designed to protect the clips from moisture and mechanical damage during transit. -
Q: Can you supply clips in other surface treatments, such as zinc plating or phosphating?
A: Yes, we can offer alternative surface treatments (e.g., hot-dip galvanizing, mechanical zinc plating, phosphating) based on your project requirements. Please specify your preference when inquiring.
