A tie plate, also known as base plate or sole plate, which is a steel plate that used between the steel rail and railway sleeper. Tie plate basically has some holes and shoulder(s). But there is no shoulder in some types of tie plate. Rail tie plate usually has tapered side to improve the stability and reduce the twisting and torsion of rails.
Rail tie plates are used not only to support the rails, but also to fix the entire rail fastening systems. It always works together with anchor bolts or spikes by sustaining the load of a rail track and also transferring part of the load to the tie sleepers, with a flat smooth resting surface to guarantee the vertical alignment and hold the rail in correct gauge for a rail line system.
GNEE RAIL is capable of producing rail tie plates by either casting(welded or fabricated type) or forging or rolling, applicable of different rail sections, for wooden, steel or concrete sleepers, depending on the load and rail standard, i.e. UIC 60, UIC 54, RN 45, 90 A, etc.
Specification of Rail Tie Plate
| Rail tie plate | Applicable condition | Processing way | Material |

Railroad tie plate give support to rail and make railway track reliable and safe with other rail components, such as railway fish plate, rail clip and railroad spikes.
