Rail Tie Plate

A rail tie plate is a board used to connect two railway tracks, usually used in railway switches, track joints, etc. The material of the connecting plate is mostly steel, and the surface treatment can be natural color, galvanized, hot dip galvanized, rough surface, copper plating, oxidation black and so on. According to different specifications and uses, railway connection plates have different weights, common 10kg, 18kg, 30kg, 38kg and so on. The main differences between railway connection plates of various materials are their manufacturing materials, physical and chemical properties, use environment and application range. 

Steel: is a common rail connection material, with high strength, corrosion resistance and wear resistance, suitable for a variety of environmental and climatic conditions. At the same time, steel can be strengthened and protected by means of heat treatment and surface treatment to improve its performance and service life.
Aluminum alloy: Aluminum alloy rail connection plate has the advantages of light weight, good corrosion resistance, good processing performance, high strength, suitable for high-speed railway, urban rail vehicles and so on. In addition, aluminum alloy rail connection plate also has excellent electrical conductivity, can be used in electrified railway contact line and other high electrical conductivity requirements.
Copper: Copper connection plate is mainly used for electrified railway contact line, has excellent electrical conductivity and corrosion resistance, and can meet the needs of high-speed electrified railway. At the same time, the copper connection plate also has high strength and stiffness, and can withstand greater pressure and impact.
Cast iron: The connection plate made of cast iron is mainly used in the railway with high strength and stiffness, and can withstand greater pressure and impact. At the same time, the cast iron connecting plate also has good wear resistance and impact resistance, which can meet the needs of long-term operation of railway lines.
In general, rail tie plates of various materials have their unique characteristics and scope of application, which need to be selected according to the specific use environment and needs.
