High-Quality Metal Tie Plates from China Suppliers - Compliant with EU EN 13481 & US AREMA Standards
Basic Information
These metal gauge plates and base tie plates are core load-bearing components in EU/US standard compliant rail fastening systems. Metal gauge plates are installed between the elastic clip and base plate to adjust rail gauge and restrict lateral displacement of rails, while metal base tie plates bear and transfer vertical wheel-rail loads to sleepers, avoiding concentrated stress damage to track beds.
EU Market Standards
Adhering to EN 13481 standards, these components are manufactured using QT450-10 ductile iron conforming to EN 1563 specifications. They are engineered for 350km/h high-speed rails and 25t axle-load heavy-haul lines, ensuring full compatibility with Pandrol Fastclip and Vossloh SKL fastening systems.
North American Standards
Following AREMA Chapter 5 rules, grade A cast steel or malleable iron base plates are required for 40t axle-load heavy-haul freight lines. These plates feature pre-drilled holes designed to perfectly match standard AREMA rail profiles and sleeper dimensions.
Technical Specifications & Durability
- Corrosion Resistance: Hot-dip galvanized or dacromet coatings passing 1000+ hour neutral salt spray tests.
- Temperature Tolerance: Designed to adapt to extreme weather conditions ranging from -45℃ to 75℃.
- Dynamic Durability: Passes 5 million dynamic load cycle tests without deformation or cracking.
- Gauge Adjustment: Supports ±8mm to ±12mm rail gauge adjustment by changing thickness.
- Cost Efficiency: Eliminates the need to replace base plates, significantly cutting maintenance costs.
- Custom Sizes: Custom sizes are available to meet specific project requirements.
Frequently Asked Questions
Metal gauge plates are installed between the elastic clip and base plate to adjust rail gauge and restrict lateral displacement. Metal base tie plates bear and transfer vertical wheel-rail loads to sleepers, which prevents concentrated stress damage to track beds.
They comply with EN 13481 standards and are made of QT450-10 ductile iron conforming to EN 1563. They are suitable for 350km/h high-speed rails and 25t axle-load heavy-haul lines, and are fully compatible with Pandrol Fastclip and Vossloh SKL fastening systems.
For North American markets following AREMA Chapter 5 rules, the base plates are made from grade A cast steel or malleable iron, designed to handle 40t axle-load heavy-haul freight lines.
The products feature hot-dip galvanized or dacromet anti-corrosion coatings that pass 1000+ hour neutral salt spray tests, allowing operation in temperatures from -45℃ to 75℃. They also pass 5 million dynamic load cycle tests without deformation or cracking.
The gauge plates support a rail gauge adjustment range of ±8mm to ±12mm by changing the plate thickness. This allows gauge correction without needing to replace the entire base plate, thereby cutting overall maintenance costs.
Yes, custom sizes are available to meet the specific requirements of special railway projects.
