China Suppliers Factory Metal Gauge Plates and Base Tie Plates for Rail Fasteners - EN 13481 & AREMA Compliant
Basic Information: Metal Gauge Plates & Base Tie Plates
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.

Frequently Asked Questions
Metal gauge plates are installed between elastic clips and base plates to adjust rail gauge and restrict lateral displacement. Base tie plates bear and transfer vertical wheel-rail loads to sleepers, preventing concentrated stress damage to the track bed.
They comply with EU standards (EN 13481, using EN 1563 material specifications) and North American standards (AREMA Chapter 5 guidelines).
For the EU market, they are made of QT450-10 ductile iron. For the North American market, they are manufactured using grade A cast steel or malleable iron.
They feature hot-dip galvanized or dacromet coatings that pass 1000+ hour neutral salt spray tests, allowing them to adapt to temperatures from -45℃ to 75℃. They also pass 5 million dynamic load cycle tests without cracking or deformation.
The gauge plates allow for a ±8mm to ±12mm rail gauge adjustment simply by changing their thickness. This eliminates the need to replace the entire base plate, significantly lowering ongoing maintenance costs.
Yes, custom sizes can be provided to meet special project requirements.
