As a dedicated manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory has been supplying reliable rail fastening components to global markets. Our 2-type Elastic Rail Clip is engineered specifically for heavy haul railway tracks, mining operations, and port terminals where maximum clamping force and fatigue resistance are critical. With annual export value exceeding US$5 million and shipments to over 15 regions including North America, Europe, and Africa, we understand the demands of the toughest rail environments.
This clip is designed to provide consistent toe load and safe rail fixation under extreme conditions. The 2-type shape (also known as e-clip) offers excellent elasticity and durability, reducing maintenance frequency and extending track life. Our clips are manufactured from premium spring steel with precise heat treatment to ensure uniform hardness and performance batch after batch.
Key features include:
- High clamping force: Maintains consistent toe load of 10-12 kN per clip, preventing rail creep and gauge widening.
- Superior fatigue life: Tested for over 3 million cycles without failure, ideal for high-frequency heavy haul lines.
- Corrosion resistance: Black oxide or oiled surface treatment protects against rust in humid mining and port environments.
- Easy installation: Compatible with standard rail fastening systems, no special tools required.
- Customizable dimensions: Available in various wire diameters (e.g., 13mm, 14mm, 15mm) to match different rail profiles (UIC60, 54E1, 50E2, etc.).
Technical specifications are summarized below:
| Parameter | Value |
| Material | Spring Steel 60Si2Mn (or equivalent per ASTM A67) |
| Type | 2-type (e-clip design) |
| Surface Treatment | Black Oxide or Oiled (optional) |
| Hardness | 40-48 HRC |
| Tensile Strength | ≥1200 MPa |
| Toe Load (per clip) | 10-12 kN (adjustable via design) |
| Fatigue Life | >3 million cycles |
| Weight (approx.) | 0.5 kg/piece |
Benefits for your operations:
- Reduced track maintenance costs – longer service intervals mean less downtime.
- Enhanced safety – reliable clamping prevents rail buckling and derailments.
- Compatibility with existing systems – can be used with standard insulator and shoulder assemblies.
- Cost-effective solution – competitive pricing without compromising quality.
- Global logistics support – shipped from major Chinese ports (Tianjin, Qingdao, Shanghai) with flexible delivery terms.
Our factory has been producing wire mesh and rail hardware since 1998, with a strong focus on quality control. Each batch of clips undergoes dimensional inspection and hardness testing before packaging. We serve clients in North America, South America, Europe, Africa, Southeast Asia, and Oceania, with annual export value reaching US$5-10 million.
We are committed to meeting your specific requirements. Whether you need a different wire diameter, surface treatment, or packaging, we can customize the clip to your specifications. Our experienced team will provide technical support throughout the ordering process.

Frequently Asked Questions
Q1: What is the difference between a Type 2 clip and other rail clips (e.g., Type 1, Type 3)?
A: Type 2 (e-clip) has a distinct shape that provides a balanced toe load and is widely used in heavy haul applications. It offers better fatigue resistance compared to Type 1 and is easier to install in confined spaces.
Q2: Can these clips be used on curved tracks?
A: Yes. The elastic design allows the clip to accommodate slight rail movements on curves. For tight curves, please consult our technical team for recommended toe load adjustments.
Q3: What rail profiles are compatible with your 2-type clips?
A: Our clips are commonly used with UIC60, 54E1, 50E2, and AREMA 115RE/136RE profiles. Custom dimensions can be produced to match other standards.
Q4: Do you provide samples for testing?
A: Yes. We offer free samples for evaluation (shipping charges apply). Contact us to arrange sample delivery to your location.
Q5: What is the typical lead time for bulk orders?
A: For standard sizes, lead time is 15-25 days after order confirmation. Custom orders may require 30-40 days depending on quantity and specifications.
Q6: How do you ensure the quality of the clips?
A: Each production batch is sampled for hardness, tensile strength, and dimensional accuracy. We also perform fatigue testing on representative samples. Our quality control system has been refined over 20+ years.
Q7: Can the clips be supplied with a different surface treatment, such as zinc plating or Dacromet?
A: Yes. We offer optional surface treatments including hot-dip galvanizing, zinc plating, and Dacromet coating. Please specify your requirement when ordering.
Q8: What is the minimum order quantity (MOQ)?
A: MOQ for stock items is 5000 pieces. For custom sizes, MOQ may be higher. We can discuss flexible terms for trial orders.
