JIS50N Rail Fish Plates
Glory Track produces JIS50N rail fish plates, also known as rail joint bars or splice bars, for JIS-standard track systems. Each fish plate is made to match the JIS50N rail profile (50 kg/m) and works together with our fish bolts, nuts, and washers to form a reliable rail joint. As demand for JIS rail networks continues to grow, JIS50N rail fish plates have become an essential part of keeping the track stable and easy to maintain.
Key Features & Benefits
Tight fit for JIS rails: hole spacing and shape match JIS50N profiles for clean alignment.
Fast installation: bolted joints speed up track assembly and shorten maintenance windows.
Simple replacement: swap a damaged fish plate without removing nearby rail sections.
Corrosion options: galvanized or coated finishes extend service life in coastal or humid sites.
Complete supply: fish plates, fish bolts, nuts, washers, and accessories available from one supplier.

Manufacturing & quality control
Glory Track runs forging, milling, precision drilling, heat treatment, and finishing lines dedicated to fish plates. We check each batch for:
- dimensional accuracy (flatness, hole alignment)
- mechanical properties (hardness, tensile)
Custom options
We accept drawings for nonstandard hole spacing, extra length, countersinks, chamfers, and special alloys. We can also supply insulated fish plates and shaped fish plates on request.
