● 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.
