FAQ
Q: What is the function of a rail fish plate?
A: It connects two rail ends securely, maintaining alignment and distributing load to prevent rail deformation.
Q: What materials are used?
A: High-carbon steel (55#/Q235) or alloy steel (B7) with hot-forged & heat-treated for durability.
Q: What's the service life in high-traffic lines?
A: 10-15 years under standard loads (25-30 ton axles), with thicker designs for mining/heavy-haul.
Q: Are bolt holes pre-drilled for easy installation?
A: Yes, precision CNC-drilled holes with standard spacing (e.g., 4-hole or 6-hole patterns).
