FAQ
Q: What is a tie plate?
A: A tie plate (or base plate) is a steel or composite plate placed between the rail and wooden/concrete sleeper (tie) to distribute load, prevent rail cutting into the sleeper, and maintain proper gauge alignment.
Q: What are the main types of tie plates?
A: Flat Tie Plates: Basic design for light rail applications
Shouldered Tie Plates: Provide lateral rail support (common in mainlines)
Sloped Tie Plates: For cant adjustment (1:20 or 1:40)
Insulated Tie Plates: Used in electrified tracks for isolation
Q: What materials are tie plates made from?
A: Steel (Manganese/Carbon): Most common, durable, and cost-effective
Composite (Nylon/Fiberglass): Lightweight, corrosion-resistant, used in special environments
Ductile Iron: For heavy-haul or high-impact areas
