Product Description

 

 A rail pad, also called rail rubber plate, is designed between the rail tie plate and foot of the rail, made by an elastic polyurethane mat, which is interposed between steel rails and tie sleepers to protect the sleeper top from wearing and impacting. Its defined stiffness is used to increase the elasticity of the superstructure of the ballast and reduce shock and vibration in the rail system. With such upgraded load distribution, it will lead to greater passenger comfort and less wearing onto the superstructure. The strengthened elasticity effects positively onto the wear of the superstructure items and rolling stock. It's always fastened within a fastening system by screw spikes or rail bolts into the sleeper ties. The reason why rail pad made up of rubber or plastic is to dampen the shocks or vibration of a passing train. Usually the starting stiffness is designed a little low in order that the relative deformation under the spring clip toe loads is substantial, which can guarantees the rail pad maintaining in close contact with the rail in spite of any vertical movements of the latter.
Rail pad is a kind of rail fasteners used between the rails and the tie plate, and it is usually made of elastic polyurethane mat. It is usually used under the rails and above the tie plate. Rubber rail pad can buffer the shake that the vehicles pushed on the tie plate and protect the tie plate and the sleeper from abrasion and impaction and prolong the service life of other fasteners. 
Shanghai Bosheng Industries Co., Ltd is an ISO 9001/2008 certified company. All processes are in accordance with the requirements of ISO quality management system, from supplier quality control to finished products, we are in accordance with the standard procedures, we have strict quality control system for suppliers:
1. Before producing Rail Pad, we will check and test the raw materials. we require suppliers to provide production batch number, chemical composition, mechanical properties and other testing indicators.
2. Our quality control inspectors take sample sampling and batch testing after the process of manufacturing Rail Pad, and provide raw material certificate and other means to control the testing process.
3.According to the different requirements of Rail Pad, we make the corresponding physical and chemical testing and inspection. If the results do not meet our requirements, we will refuse to accept the materials only if they meet our standards.
4. For semi-finished products and their external suppliers of Rail Pad, we often organize quality control coordination meetings and provide technical advice and guidance. Ensure that qualified products are delivered to our customers prior to shipment.
