Railway HDPE Plastic Sleeves In Concrete Ties White Or Yellow Color
General Introduction of HDPE Plastic Sleeves
HDPE Plastci Sleeves is used to fasten rails. Together with the screw spikes, it gives more strength to ensure that rail is fixed firmly. It is put in concrete railroad ties and the material is usually HDPE or PA66.
