Adhering to our quality first policy, SUYU pays great attention to quality control management. We have been granted ISO9001-2008 certificates and have received the production license of China's Railway Ministry on railway products. We have a full set of inspection instruments to ensure all our rail plastic sleeve are of high quality and up to customers' requirements.

As a leading manufacturer of rail fastening based in China, SUYU also produces many other railway fasteners, such as track bolt, sleeper screw, track spike, tie plate, rail clip, elastic rail clip, SKL tension clamp, rail shoulder, and so on.



rail insulator

We produce E type rail insulator and guide plate for SKL rail fastening and Nabla fastening system. The material we use for rail insulator is PA66, with the color white, dark brown and black. Our rail nylon insulator is used to adjust rail gauge and insulate the rail from ties and clips.

The material properties of PA66 are listed below.

Rail Pad

The rail pad, originally called sole plate, is used when rail is attached to concrete, rather than timber, ties or sleepers. Rail pads function to reduce fatigue cracking of the concrete ties, believed to be driven by impact and vibration from the passing train. It is thought that the rail pads act in two ways: they diminish shock or impact loads by providing compliance, and they reduce (by isolation and perhaps by damping) resonant vibrations excited in the concrete ties (lowest resonant frequency about 200 Hz) and accommodate vibration deflections in the rail sections between the ties (about 0.12mm amplitude, 1000 Hz).

The raid pad prevents rail-sleeper abrasion and the crushing of the sleeper under the rail foot. Rubber rail pads are normally designed to a specified load-deflection characteristic. The initial stiffness of the rail pad is designed to be low so that that their deformations under the springs toe loads is quite substantial. This ensures that the rail pad remains in intimate contact with the rail despite any vertical movements of the latter. When the wheel is over the pad, the latter's stiffness must be high to prevent large movements which can result in the metal spring becoming loose. S
