The rail joint bar, commonly known as fishplate, serves as a vital component in railway fastening systems for connecting adjacent rails. Its structural design and type directly impact track stability and service life. Based on different track conditions and application requirements, fishplates can be categorized into four main types, each with distinct structural features, suitable applications, and installation accessories.
Common rail fishplates are typically manufactured from standard Q235 steel material, suitable for various types of rail tracks. The appearance and weight of ordinary rail joints vary according to different rail weights, with main types being 4-hole and 6-hole configurations. As a professional railway fastener supplier, GNEE RAIL offers a comprehensive range of railway fasteners, including both standard and customized products.

Insulated Rail Joints are specifically designed for electrified railways and signal sections. These incorporate insulating materials to isolate electrical current and prevent signal interference while maintaining excellent mechanical strength. This type is typically used with accessories like Insulated Gauge Blocks and Rail Pads to ensure stable operation of signaling systems.
Non-standard railway fishplates encompass various types within all rail joint categories. Depending on different railway sections and speed requirements, some rail joints differ from standard fishplates. Generally, non-standard rail joints can be categorized by different weights, pitches, and appearances.
Compromise rail joints differ from non-standard types. Common compromise rail joints include bulge railway fishplates and railway Switch Expansion Joints. These are typically custom-made and primarily used in switch expansion joints or specially designed railway sections. Compared to other types, compromise rail joints are more complex to manufacture.
