AREMA Standard Fish Plate (Rail Joint Bar)
The AREMA Standard Fish Plate—also known as a rail joint bar—is an essential component for connecting two rail ends in heavy-haul, mainline, and industrial railway systems. As a professional rail joint bar supplier, Glory Track manufactures AREMA-compliant fish plates engineered for long service life, precise fit, and stable load transfer.
Compared with rail butt welding, our AREMA fish plates enable faster installation, easier maintenance, and reduced downtime—making them a preferred solution for railway contractors worldwide.
Key Features & Benefits
- Reliable Load Distribution
Machined contact surfaces ensure stable bending and shear load transfer, reducing stress concentration at the rail joint. - Enhanced Fatigue Performance
Heat-treated steel improves wear resistance and extends service life under continuous vibration and dynamic loading. - Precision Fit for AREMA Rail Profiles
Hole spacing and machining tolerances are controlled to guarantee proper alignment and tight clamping with 115RE–141RE rails. - Fast Installation & Easy Replacement
Compared with welded joints, fish plate assemblies shorten installation time and reduce rail downtime—ideal for maintenance or emergency replacement. - Complete Joint System Supply
Matching bolts, nuts, washers, and optional protective coatings are available, allowing customers to source an entire rail joint system from one supplier.
