Is surface treatment necessary for rail clips?

In the railway track system, rail clips, often called an elastic rail clips, railway clips. What's function of rail clips? Through the bending deformation of the elastic rail clips, the buckle pressure acts on the track, which can effectively ensure the reliable connection between the rail.

GNEE RAILWAY RAILWAY offer an extensive range of rail clips with optimum quality, these rail clips are designed with high precision and made up of premium grade spring steel. GNEE RAILWAY has been the largest and most competitive production base of rail clip in China after more than 20 years' rail clip producing experience, and have qualification to tender nationally large and medium scaled rail projects. What's more, our rail clip can be customized according to clients' requirements.

Yes, surface treatment is necessary for rail clips to enhance their durability and corrosion resistance. Without it, clips can quickly degrade due to environmental factors like moisture and chemicals, leading to premature failure. Common treatments include galvanization, specialized coatings for different environments (like for coastal or chemical-polluted areas), and painting.

Why surface treatment is essential

• Corrosion protection: Rail clips are exposed to harsh environments, including moisture, salt spray, and industrial chemicals. Surface treatments like galvanization create a protective barrier that prevents rust and corrosion.

• Enhanced durability: Treatments can improve the overall lifespan of the clip by protecting it from wear, abrasion, and other forms of damage.

• Environmental adaptation: The specific surface treatment can be tailored to the application's environment. For example:

                                                          Coastal areas: Hot-dip galvanizing combined with a sealing coating is effective against saltwater.

                                                         Chemical-polluted areas: PTFE coatings offer excellent chemical resistance.

                                                         Frigid regions: Zinc-nickel alloy coatings are used for good low-temperature toughness.

• Aesthetics: In some applications, a consistent appearance is desired, which can be achieved through painting or other coatings.

Common surface treatments

• Galvanization: A process where steel is coated in a protective layer of zinc, providing excellent corrosion resistance.

• Coating: Various coatings can be applied, such as Dacromet, anti-rust paint, or specific coatings like PTFE for chemical resistance.

• Painting: A common method for both protection and aesthetics.

• Plain (oiled): Some clips are left with a simple oil coating, especially if a more robust treatment isn't required.
