Rail pads are widely used in the railway fastening system. They are placed between the steel rail and the sleepers or tie plates for the purpose of eliminating the shocks and vibration caused by passing train. With the elasticity characteristics of rubber and eva and hdpe material, rail pad can keep the closed contacting with the rail above and the sleeper and tie plate underneath.
Not only for the advantages of above mentioned points, the rail pad can perform the function as below:
Load distribution for the passing train on rail
Elimination of load concentration and stresses
Absorption of uneven contact surfaces between rail and support
Reduction of noise and vibration
We can supply wide range of rail pads from trams and heavy hauled lines, as well as all standard gauge rail tracks. Including rail pads for E type rail fastening systems and SKL type rail fastening systems
We have three kinds of materials for produciton of rail pads: HDPE, EVA and Rubber. Below are the differences of the three rail pads differences.
