Rail pads are elastic polyurethane pads, installed directly under the steel rail. They have a defined stiffness to increase the elasticity of the ballasted superstructure. The improved load distribution yields greater passenger comfort and less wear on the superstructure. It can be made of HDPE, EVA, rubber, and EPDM to preclude and buffer impact, increase friction and reduce vibration. We produce the rail pad for E type rail fastening system and SKL type rail fastening system
We can supply rail pad with a thickness ranging from 5mm to 25mm thick. Pads made of metal bonding are used to reduce extensive vibrations.
We offers a wide range of rail pads for every required stiffness rating, from standard gauge tracks to tram tracks. We are a leading rail plastic dowel manufacturer in China. We can also make other rail fastenings such as railway screw, plastic dowel, rail pad, railway insulator, rail fish bolt, railway base plate, rail anchor, railway shoulder, rail bolt, flat and spring washer, fastening system of E type/SKL type/KP type/Nabla type.
