Rail pads are elastic polyurethane mats which are interposed between steel rails and railway sleepers to protect the sleeper top from wearing and impacting.The starting stiffness of a rail pad is designed to not be high so that their relative deformation under the spring clip toe loads is greatly substantial. In this way, it can guarantees the rail pad maintaining in close contact with the rail despite of any vertical movements of the latter.
GNEE RAIL commonly uses materials such as rubber, EVA, HDPE, and high-density polyurethane to manufacture rail pads. These pads interact with railway fasteners including spikes, bolts and nuts, fish plates, rail anchors, and others to ensure railway operational safety.
