A rail fish plate is a mechanical coupling device that allows separate rail lengths to behave as a continuous structural member by transmitting loads through bolted steel interfaces rather than rail-end contact alone. GNEE RAIL manufactures fish plates for GB rail standards, UIC rails, JIS profiles, AS1085 rails, BS11 sections, AREMA/ASCE systems, and crane rails including DIN536 A55–A120 and QU70–QU120, with installation guidance support.

Specification Drawings of 115RE rail joint bar
A 115RE joint bar (also known as a fishplate or splice bar) is a heavy-duty steel connector used to join two 115 lb/yd (115RE) rail sections together in railway tracks. Designed to AREMA standards, these bars are bolted to the rail ends to maintain structural alignment and ensure safe, continuous rail passage, typically featuring 4 or 6 holes.

Why use 55# material to manufacture the 115RE rail joint bar?
55# steel (a medium-high carbon steel) is used for 115RE rail joint bars (fish plates) to provide high strength, durability, and excellent wear resistance. It ensures the joint, the weakest part of the track, can withstand heavy loads, prevent bolt hole elongation, and endure high-impact, high-frequency stress.
- High Strength and Durability: 55# steel, with carbon content around 0.50–0.60%, offers superior mechanical strength compared to lower-grade steels, essential for supporting heavy-duty rail traffic.
- Optimal Hardness and Wear Resistance: The material is often heat-treated (quenched and tempered) to increase hardness and wear resistance, significantly extending the service life of the joints.
- Impact Resistance: Joint bars require toughness to absorb the constant impact from wheels passing over the rail gap, which 55# steel provides efficiently.
- Excellent Matching with 115RE Rails: 55# steel is frequently used to manufacture joint bars that perfectly match the profile and physical properties of 115RE rails.
In summary, 55# steel is chosen because it offers the best balance of mechanical strength, wear resistance, and toughness needed for structural stability at the rail joint.
