Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer since 1998, specializing in high-precision railway fastening components. Our Heat Treated Type I Elastic Rail Clip with a 12mm diameter and 150kN clamping force is designed to deliver exceptional holding power and fatigue resistance for heavy-haul and high-speed rail lines. Backed by over two decades of manufacturing expertise and an annual export value of US$5–10 million, we supply this rail clip to demanding markets across North America, Europe, Southeast Asia, and Oceania. This product is engineered to reduce maintenance costs, increase track stability, and ensure long service life under extreme conditions.

Product Features and Technical Specifications

Precision 12mm Diameter: The clip is made from high-quality spring steel rod (60Si2Mn or 55Si2Mn) with a consistent 12mm diameter, ensuring uniform stress distribution and reliable clamping force.
Heat Treated for Strength: Undergoes a controlled quenched and tempered process to achieve optimal hardness, elasticity, and toughness. The heat treatment eliminates internal stresses and enhances fatigue life.
150kN Clamping Force: Delivers a powerful clamping force of 150 kilonewtons, securely fastening the rail to the sleeper and preventing lateral displacement or gauge widening.
Type I Design: Conforms to the Type I elastic rail clip profile, widely used in standard railway fastening systems. Compatible with most standard rail pads and base plates.
Excellent Corrosion Resistance: Available with optional surface treatments such as plain finish, oiled, or black oxide coating to resist rust and prolong service life in harsh environments.
High Fatigue Resistance: Tested to withstand millions of load cycles without failure, ensuring long-term reliability in high-traffic corridors.
Easy Installation: Designed for simple manual or mechanical installation, reducing labor time and costs.

Key Benefits for Your Railway Operations

Enhanced Track Stability: The 150kN clamping force effectively locks the rail in place, minimizing track gauge variation and reducing the risk of derailment.
Reduced Maintenance Frequency: Thanks to the high fatigue resistance and heat treatment, the clip maintains its elasticity over time, reducing the need for frequent retightening or replacement.
Cost-Effective Solution: Our direct factory pricing and efficient production capacity (established in 1998) allow us to offer competitive prices without compromising quality.
Global Compatibility: The Type I design is recognized and used in many railway systems worldwide, making it a versatile choice for both new installations and replacement projects.
Customizable Options: We can adjust surface finish, hardness, or even dimensions (within limits) to meet your specific project requirements. Contact us for customization.

Frequently Asked Questions (FAQ)

Q: What is the exact clamping force of this rail clip?
A: The minimum clamping force is 150 kN, as tested under standard conditions. The actual force may vary slightly depending on the rail profile and base plate configuration.
Q: Is this clip compatible with all rail types?
A: Yes, the Type I elastic rail clip is designed to work with standard rail profiles such as 50kg/m, 60kg/m, and 75kg/m. However, we recommend verifying compatibility with your specific base plate and rail pad.
Q: What surface treatment options are available?
A: We offer plain finish, oiled, and black oxide coating. Other custom treatments (e.g., zinc plating, Dacromet) can be provided upon request with additional cost.
Q: How long does the heat treatment last?
A: The heat treatment is permanent and does not degrade over time under normal operating conditions. The clip's fatigue life is typically rated for several million cycles.
Q: Do you provide samples for testing?
A: Yes, we can provide small samples for evaluation. Please contact our sales team to discuss sample availability and shipping terms.
Q: What is the minimum order quantity (MOQ)?
A: For standard clips, the MOQ is 1,000 pieces. For custom specifications, the MOQ may be higher. We can discuss flexible terms for long-term partnerships.
Q: How do you ensure quality control?
A: We conduct incoming material inspection, in-process dimensional checks, and final testing for clamping force, hardness, and surface quality. Each batch is accompanied by a test certificate.
