A rail fish plate is a joint reinforcement bar that reduces impact loads at rail ends and prevents accelerated wear and fatigue in traditional jointed tracks. GNEE RAIL provides fish plates for GB rails, UIC rails, DIN536 and QU crane rails, JIS profiles, AS1085 rails, BS11 standards, and AREMA/ASCE sections, offering pre-assembled joint sets and international shipping solutions.

Types of Rail Joints in Track Railway
Rail joints in railway tracks connect rail ends, ensuring continuity, structural strength, and space for thermal expansion, primarily categorized by position and function. Key types include suspended, supported, bridge, square (even), and staggered joints. They are crucial for maintaining track geometry, reducing wheel impact, and supporting train load transfer.
Supported joint:
A supported joint in railway engineering features a rail joint positioned directly over a supporting sleeper or tie, rather than between them (which is a suspended joint). It aims to reduce rail end wear by eliminating cantilever action, though it often creates a stiffer ride and higher sleeper maintenance, such as with duplex sleepers.
Suspended joint:
A suspended joint is a common railway track connection where the rail joint is positioned between two sleepers, causing the rail ends to be cantilevered. It is widely used for better shock absorption and simpler maintenance compared to supported joints, though it requires more frequent sleeper packing due to potential looseness from the pounding action of passing trains.
Bridge joints:
Bridge joints are essential structural gaps in bridges that safely accommodate movement from thermal expansion/contraction, traffic loads, and seismic activity while maintaining a smooth riding surface. They prevent structural failure, reduce damage to bearings, and must be watertight to protect the infrastructure beneath. Common types include asphaltic plugs, strip seals, and large modular joints.
Components of a rail joint bar
A rail joint bar (or fishplate) is a critical fastener assembly, comprising two steel plates (inside and outside) bolted together against the rail web to connect rail ends. Key components include high-tensile steel joint bars, four to six fish bolts with nuts, and spring washers, often supported by additional fasteners like clips and tie plates.
Founded in 2008, GNEE RAIL is a leading global manufacturer and supplier of railway components, specializing in high-quality rail fish plates (joint bars/splice bars) with strong production capacity and global service capabilities.
Our rail fish plate portfolio is comprehensive and compliant with international standards including UIC, AREMA, BS, DIN, and GB, covering light rail (8kg-30kg), heavy rail (38kg-75kg), and crane rail (QU70-QU120) systems. We offer diverse types such as insulated joint bars, bulged fish plates, and compromise rail joints,with precise specifications (4-hole/6-hole, 24-inch/36-inch), ensuring excellent mechanical performance.We uphold strict quality control supported by ISO 9001:2015 certification, an in-house inspection center, and third-party audits by SGS and BV. Our one-stop service includes customization, production, packaging, and after-sales support, tailored to clients' project needs.
