What materials are commonly used for rail pads

Aug 12, 2025 Leave a message

Rail pads are elastic polyurethane mats which are interposed between steel rails and railway sleepers to protect the sleeper top from wearing and impacting.

 

GNEE RAIL have developed a range of high-performance elastic rail pads for stiffness requirements and various application areas-from trams through standard gauge railways to heavy haul lines, especially those for E-type rail fastening systems and SKL type rail fastening systems with material of HDPE/EVA/Rubber, with following properties respectively.
