BS80A Fish Plates (Rail Joint Bars)
BS80A fish plates, also called BS80A rail joint bars or BS80A rail splice bars—are steel connectors used to join two BS80A rails (80 lb/yd).
They stabilize the rail ends, maintain gauge, and absorb vertical and lateral forces during rail operations.
Glory Track supplies BS80A fish plates engineered for secure rail joints, stable running performance, and long service life in heavy-duty railway lines.
Made from high-strength carbon steel and precision-machined for BS80A rail profiles, our BS80A rail joint bars ensure smooth load transfer, accurate rail alignment, and reliable performance in demanding environments such as industrial railways, mining tracks, and mainline upgrade projects.
Key Features of BS80A Fish Plates
- Exact BS80A Rail Compatibility
Manufactured according to BS47-1, ensuring a perfect fit for all BS80A rail sections. - High-Strength Carbon Steel
Available in 55# steel or Q235, providing excellent mechanical properties and long-term durability. - Precision Machining
Bolt holes, straightness, and end surfaces are machined to tight tolerances for stable load transfer and smooth rail joints. - Anti-Corrosion Surface Options
Choose from black treatment, painting, or galvanizing based on project needs. - Available in 4-Hole or 6-Hole Designs
Fully compatible with standard BS80A railway joint configurations.
