Fish Plate/Joint Bar

Rail joints, usually called fish plate, commonly known as the joint bar, is a component that joint rails end-to-end. It is applied to light rail, heavy rail and crane rail. There are holes in the middle of the fish plate for rail bolt to screw. The top and bottom of the fish plate are made into slopes corresponding to the slope of the lower part of the railhead and the top part of the rail bottom. Thanks to the design which helps the joint bars wedge the rails, the rail joints can be bolted to the rail very tightly. Therefore, good rail joints can reduce the impact of wheels at the joint and improve the smoothness of the passing trains.

While welded rails are quickly developed and used more often, the rail joints still have their advantages of saving cost and labor since its simple and quick installation. The working state and safety performance of the rail joints directly affect the running state and safety of the line.

According to the raw materials used, rail joints can be divided into ductile iron, Q235 type, and Q255 rolling type, forging type, etc. In general, medium and high carbon steels are used as raw materials. According to different applications, rail joints can be divided into bolted rail joints, compromise rail joints and insulated rail joints.
