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: Can fish plates withstand extreme temperatures?
A: Yes, tested for -40°C to +70°C without brittleness or strength loss.
Q: Can fish plates be reused after rail replacement?
A: Yes, if undamaged – inspect for cracks/deformation before reinstallation.
Q: How to reduce wear at rail joints?
A: Use our lubricated fish plates or abrasion-resistant coatings to minimize friction.
