What are the advantages of applying plain (oiled) surface treatment to Rail Clips?

A rail clip is an essential fastening device that secures steel rails to railway sleepers. These clips ensure reliable connections between rails and sleepers while maintaining track integrity during temperature-induced expansion and contraction. Rail clips also absorb shock produced by passing trains, reducing stress on the track structure.

As an OEM & OBM manufacturer, GNEE RAIL is capable of not only producing a wide range of internationally common types of rail clips, such as W Tension Clamp, e-Clip, Fast-Clip, SKL Tension Clamp, Nabla Blade, etc., but also customizing products tailored to our customers' specific requirements.

The main advantage of applying a plain (oiled) surface treatment to rail clips is that it is a low-cost, temporary method for corrosion protection. This treatment provides a basic, temporary barrier against rust by applying a layer of oil, making it suitable for applications where cost is a primary concern and long-term durability is not the highest priority.

Advantages of plain (oiled) treatment

• Low cost: Applying oil is a very inexpensive process compared to other treatments like galvanizing or specialized coatings.

• Basic corrosion protection: The oil forms a protective layer on the metal, preventing moisture and oxygen from reaching the surface and causing rust.

• Temporary: The oil-based protection is not permanent and will wear off over time, requiring reapplication or a more durable coating for long-term use.

Limitations and alternatives

• Limited durability: For applications with harsh environmental conditions, such as high moisture or chemical exposure, this basic treatment may not be sufficient and can lead to premature failure.

• Alternative treatments: More durable options, such as zinc plating (galvanizing), Dacromet coating, or epoxy painting, are widely used for better long-term corrosion resistance in demanding environments.

Furthermore, GNEE RAIL offers a diverse range of products and services, including OEM and OBM rail fastening systems for conventional, high-speed, heavy-haul, and metro applications. Its portfolio includes rail clips, pads, tie plates, bolts, and other specialized components. Comprehensive laboratory facilities ensure all products meet rigorous standards, including EN 13146, EN 13481 internationally, and TB standards domestically in China.
