Fish plates railway offer a practical and efficient alternative to welding, simplifying installation and reducing labor costs. Designed for quick and easy assembly with matching fish bolts.
Xingrail is a professional manufacture a comprehensive range of fish plates for light, heavy, and ultra-heavy rail applications. Each plate features a unique arched bridge design, engineered to minimize the impact from train wheels passing over the joint. This innovative structure enhances the longitudinal continuity of the rail, reduces wear, and ensures a smoother, safer ride. By improving train passage stability and absorbing shock, our fish plates extend the life of your track and guarantee superior performance and durability.
