Feb 06, 2026 Leave a message

A rail fish plate is a steel bar installed at rail ends to maintain track geometry, resist vertical and lateral forces, and ensure continuity of the load-bearing path across a joint. GNEE RAIL manufactures fish plates compatible with GB light and heavy rails, UIC50–UIC60, DIN536 A55–A120, QU70–QU120 crane rails, JIS rail sections, AS1085 profiles, BS11 rails, and AREMA/ASCE standards, with full support for custom project requirements.

What is the size of Japanese Standard Fishplate?

 

A Japanese Standard (JIS) rail fish plate, or joint bar, is a specialized steel fastener designed according to Japanese Industrial Standards (JIS E series) to connect two rail ends securely. These plates ensure consistent track alignment, strength, and load transfer in railway systems, commonly produced for JIS 30A, 37A, 40N, 50N, and 60kg rail profiles.

How are rail joint bars manufactured?

 

Rail joint bars (fishplates) are manufactured through a process of shaping hot-rolled steel, followed by heat treatment, punching/drilling, and finishing to ensure high strength and durability. They are typically produced from carbon or microalloyed steel, which is forged to exact profiles, quenched for hardness, and finished with protective coatings.

 

Key Manufacturing Processes

 

  • Material Preparation: The process starts with high-quality carbon or microalloyed steel.

 

  • Forging and Shaping: The steel is heated to high temperatures and shaped using rollers or presses to match specific rail profiles (e.g., UIC 60, 136 RE). This ensures a dense, uniform, and defect-free structure.

 

  • Punching and Drilling: Bolt holes (usually 4 or 6) are punched or drilled, and in some cases, joint bars are slotted.

 

  • Heat Treatment (Quenching & Tempering): To enhance hardness, durability, and wear resistance, the bars are heated and then rapidly quenched.

 

  • Finishing: The bars are cleaned, straightened, and often coated to prevent corrosion.

 

  • Quality Control: Inspections include dimensional checks, ultrasonic testing for internal flaws, and hardness testing.

 

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.
