The fish  plate is made of: B7, 45 #, Q235 rolling, forging etc. The fish plate mainly uses carbon steel and high carbon steel as raw materials.

The manufacturer:

The fishtail plate production in great, Henan province is very focused on quality control and management. Our fishplate production is completely controlled by the iso9001-2008 quality system, and we have obtained the railway product license from China railway ministry. We have a complete set of inspection equipment to ensure all of our products quality and meet customer's requirements.




The fish plate (the rail joint splint) is commonly known as the road splint, which is connected at the junction of the track. A fish plate is a kind of fastening used for the connection between orbit and orbit. The use of the fish plate is more convenient than the rail butt welding technology. The installation is simple and fast, and the fish plate is used with the fish bolt. Fish plate, which is equipped with the screw hole, along the horizontal axis of the screw holes on both sides of the upper and lower sets and rail head lower contact on the working face, and the lower face of the upper and rail bottom contact, described on the face at the back of the upward along the stretch forming a higher than on the surface of the rail transition section, the transition section along the fish plate length direction to form high, middle low on both ends of the bridge arch.


The structure of fish plate is simple, it can reduce the impact of the wheel on the rail joint, and increase the continuity of the longitudinal deformation of the rail, and improve the smoothness of the train.

Company profile:

Company's products have passed the quality certification testing center of the Ministry of railways , and the enterprise has a staff of 82 people, with senior engineering and technical personnel 9 people, the company has advanced equipment, machining, forging, Dacromet anticorrosion and other large equipment. Besides, our company has   strong technical force, complete detecting means , strict implementation of the Ministry of Railways standard production. Since its establishment in more than 10 years, the products have been sold well all over the country and sold to the various engineering bureaus of the Ministry of railways, the Railway Bureau, railway service section, the local railway line, the large mineral enterprises and the mineral bureau special lines of the coal system. Over the years praised by users and can also be processed according to the special requirements of customers. The company's products are widely used in high-speed rail, bridges, infrastructure, coal mines, and tunnels and so on.

Product specification: 

The fishtail plate model can be divided into 43kg, 50kg, 60kg, 75kg, UIC, German standard and American standard.

Business scope:

The series products include: all kinds of rail clips, gauge plate, all kinds of track spikes, rubber tie plate, Nylon plate, special switch  plate, rail joint splint that weights 43 kg,50 kg ,60 kg and tunnel segment bolt and so on.

Product description: 

the fish plate (rail joint splint) is commonly referred to as the road splint, which is a kind of connecting fastener used for the connection of rail and rail. It is divided into light rail, heavy rail and heavy rail. The light rail fish plate is also known as the crossbar, the heavy rail fish plate is also known as the hoisting rail. The insulating fish plate is made of insulating materials. The insulating fish plate is a new type of track material made of high strength composite material.


It is corrosion resistant, anti-rust, anti-ultraviolet, non - conductive, non - magnetic. It belongs to thermosetting material and cannot be processed twice, so it is not afraid to steal.


The reinforced fish plate of Henan great railway machinery co., LTD. was approved by the China railway research institute and obtained the patent

In recent years, the company also adheres to the principle of market orientation, ability matching, innovation and development, and the principle of local conditions, so that the company's products can be serialized, refined and branded. At the same time, according to market situation and customer feedback, continuous improvement innovation, formed a unique series of products. Its products are widely used in railway, Bridges, mines, construction and other transit and intercity rail transit lines construction, especially in the national key project, the construction of Qinghai Tibet railway, the company production of rail fittings fishplate successfully solved the plateau permafrost, bad environment conditions, such as day and night temperature difference is bigger, use to ensure the quality of the major issue. 

"According to the original standard, the fishtail plate is not able to adapt to the larger climate of the Qinghai Tibet plateau and is prone to fracture." Therefore, Henan great orbit machinery co., LTD., in conjunction with the China academy of railway sciences and Anshan iron and steel, after a lot of research and for the adjustment of the material, finally produce conform to use in the conditions of rail connection reinforced fishplate. At the same time, Henan great orbital co., LTD., as one of the standard drafting units, participated in and reformulated railway standards.
