Rail tie plate is also called rail base plate or sole plate, it is a main component in railroad construction of a crane rail or track support system.
Rail tie plates can be classified depending on either a single or double shoulder construction, GNEE RAIL can supply various ribbed tie plates. Single shoulder tie plates\Double shoulder base plates\AREMA hook twin tie plate etc.
GNEE RAIL possesses professional expertise and mature technology to ensure the quality of sleeper plates. Typically, rolled sleeper plates are manufactured using Q235 carbon steel.
Q235 carbon steel, also known as A3 carbon steel, derives its name from its yield strength: "Q" stands for yield limit, and "235" indicates a yield value approaching 235 MPa. With moderate carbon content, it offers a balanced combination of strength, plasticity, and weldability. Due to its well-rounded mechanical properties, Q235 carbon steel is widely used in railway fastening systems.
QT400-18 carbon steel is commonly used for cast sleeper plates, with casting being the most frequent manufacturing method for such components. QT400-18 is composed of iron, carbon, and silicon. It exhibits good weldability, machinability, and plasticity, along with high impact toughness at room temperature. These characteristics make it suitable for casting sleeper plates and other railway components.
White iron is often employed for forged sleeper plates. With a carbon content of approximately 2.5%, white iron is highly hard and brittle due to its substantial Fe₃C (iron carbide) content. Forging is another common method for producing sleeper plates.
Q345 carbon steel is also used for forging railway sleeper plates. This material offers excellent comprehensive mechanical properties, good hot and cold workability, and corrosion resistance. These attributes make Q345 carbon steel ideal for manufacturing high-load welded components.
