Rail Pad

Rail pads are placed between rails and sleepers to protect the tops of the sleepers from wear and impact. The rail pads are kept in close contact with the rails. Generally, the rail pads are made of rubber or plastic insulators, which act as a buffer to suppress the impact of passing train vibrations on the wear of rails and sleepers.

Rail pads are critical to reducing shock and vibration in the rail system, so materials must be wear-resistant.

The rail pads are placed under the rails to share the load on a larger surface, eliminating load concentration and resulting fatigue stresses.

It can absorb the vibration and noise caused by uneven contact surfaces between rails and sleepers

We can provide rail pads for E-type rail fixing system . SKL type rail fixing system and fist rail fixing system , respectively, with the following properties.

1、Rail pad used for E type rail fastening system

Rail pads used for E-type rail fastening systems are  functionally similar to rail insulators used to isolate rails and sleepers to  effectively prevent vibration and solid noise. Rail rad is used with Elastic  clip , rail insulator. .rail shoulder to well fix the rails .

2、Rail pad used for SKL rail fastening system

Rail pad in a SKL rail fastening system Used with SKL  clip, screw spikes, rail insulators, plastic dowels, etc. We produce rail pads  with definite stiffness and increase the elasticity of the rail's  superstructure. With this flexibility, it helps to achieve the quiet operation  of railway vehicles to meet the requirements of today's railway operations.
