Rail plastic dowel is one part of rail fastening system, it should be pre-inserted into the concrete sleeper separately before assembling the rail fastening system parts, so it can be considered as the fastening foundation.
Signum can provide different types of rail washers with various specifications to meet customers' requirements.
Below are two kinds of materials that used for manufacturing rail screw dowels: HDPE and PA66 Nylon with glass fiber.
