Fish Plate

Fish plate, also known as splice bar, rail joint or joint bar. It is a metal connecting plate used to join adjacent rails in a railway track. Its main function is to securely fasten the rails together using rail bolts or railroad spikes, ensuring the continuity and stability of the railway line. Here are some screw holes in the middle of the fish plate. It is much more labor-saving and easier to install than rail butt welding technology. Fish plates play a crucial role in the maintenance and construction of railway tracks, ensuring that railway systems operate smoothly.

The fish plate, serving as a railway joint, has a weak structure. It is required to use steel with good rigidity and toughness, enhance the allowable stress through heat treatment, and improve the hardness and wear resistance of its supporting surface. Make sure it can be securely fastened to the steel rail when trains pass through.

Fish plates are essential components in railways, and their primary role is to minimize the impact of wheels on the rail connection section, enhances the overall stability and continuity of trains as they traverse these connection points, and ensures the efficiency and safety of railway systems.

GNEE is a professional manufacturer of railway equipment, providing high-quality railway fasteners. We specialize in producing types of fish plates: normal fish plates, joggled fish plates, compromise fish plates, and more. Additionally, we provide a range of other fasteners, including fish plates, rail clips, railroad spikes, and more. And we offer customization according to customer specific requirements.

● Normal fish plate

The common rail fish plate is a widely used type of railway connector, typically made of medium carbon steel and high carbon steel. And there are two types of normal fish plate, four-hole and six-hole fish plates. It is used in conjunction with fish bolts, providing a secure fastening through the combination of elliptical holes and bolts. This type of fish plate is suitable for various rail types, and its appearance and weight depend on the different weights of railway tracks.

● Compromise fish plate

The compromise fish plate is a railway connector designed to link two different types of rail tracks. It consists of two separate sections - one installed on the outer side of the rail and the other on the inner side. The structure includes upper and lower working surfaces along the horizontal axis, with the back of the upper working surface extending upward to form a transitional part, creating a bridge arch shape along the direction of the fish plate. The compromise fish plate has a unique shape and is usually custom-made compared to the other two types of fish plates. And it is more difficult to manufacture and is mainly used in specific railway sections with special designs and requirements, such as railway turnouts.

● Joggled fish plate

The joggled fish plate has a different shape compared to the normal fish plate; it is a specially forged plate consisting of a fish plate with a raised section in the middle. The joggled fish plate can securely clamp and repair welded steel rails, ensuring the safe passage of trains on railway tracks. It has features of following rail deformations, wide applicability, easy maintenance, strong durability, simple installation, and excellent fatigue resistance.

GNEE manufactures various types of rail joint fish plates suitable for use in light rail, heavy rail, and crane rails.
