Rail Plastic Dowel is a counter-party of Screw Spike, which is pre-inserted into the concrete sleeper. When we use the rail fastening system, the plastic dowel performed as the fastening base.
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.
