Rail tie plate is also known as base plate or sole plate, used between rails and sleepers to support the rails. It is one of the main parts in railway construction.

Rail tie plate is not only used for support the rails, but also for fasten the whole rail fastening system. It is generally used in conjunction with clip, clip bolt /sleeper screw etc., to bear the loads produced during locomotive's travelling as well as transfer part of the loads to the sleepers. Its surface contacting with the rails is flat and smooth, so as to ensure the distance between the two parallel rails.

Casting, forging and rolling are three common production processes for manufacturing rail tie plate.

  1. Rail tie plate by casting
  2. Rail tie plate by rolling
  3. Rail tie plate by forging


From the perspective of production process, casting process is widely applied to rail tie plate at home and abroad due to its lowest production cost. The rail tie plates by casting are generally used on UIC60, UIC54, S49, 50kg, 60kg and many other models of rails.

In recent years, American and Canadian customers have large demands in rail tie plates by rolling. Relying on our mastered professional knowledge in rolling, together with accumulated joint bar rolling experience over the years, our factory attempt to apply rolling process to the production of rail tie plates. Up to now, we have successfully developed rail tie plates with base of 5/1/2" and 6" and width of 11", 14", 14-3 / 4" and 16", widely recognized by customers. Based on this, we have received large amount of orders from America and Canada. At the same time, there are more types under technical discussion and development preparation.
