Metro Iron Base Plate

The Metro Iron Base Plate is a high-strength railway component specifically designed for urban metro and light rail systems, providing stable support, precise rail positioning, and effective load transfer between the rail and the sleeper or concrete track bed. Manufactured from premium-grade forged or hot-rolled steel, the base plate undergoes strict heat treatment and anti-corrosion surface processing—such as hot-dip galvanizing or epoxy coating—to ensure excellent durability, wear resistance, and long service life in demanding metro environments.

Engineered with high dimensional accuracy, the Metro Iron Base Plate serves as a key interface within the rail fastening system. It evenly distributes vertical and horizontal loads generated by train operation, minimizing stress on the sleeper or slab and ensuring stable rail geometry. The plate is designed to accommodate metro rail profiles such as 50kg/m, 60kg/m, and UIC60, and can be configured for both direct fastening systems and indirect elastic fastenings. Its robust design, precision holes, and smooth surface finish ensure perfect compatibility with rail clips, bolts, and insulating pads, making it suitable for high-frequency, high-traffic metro applications.

Function & Application
The Metro Iron Base Plate plays a vital role in maintaining track stability, passenger comfort, and operational safety in metro and light rail networks. Its primary function is to support the rail base and distribute dynamic loads evenly to the sleeper or concrete bed, preventing localized stress and structural fatigue. The plate ensures proper rail gauge and alignment, minimizing rail deformation, vibration, and noise during train operation. The high rigidity and precise shape of the base plate contribute to reduced rail movement and improved long-term track geometry.

In addition to load distribution, the Metro Iron Base Plate acts as a protective interface that prevents direct contact between the rail and the sleeper, reducing wear, corrosion, and maintenance needs. When used in combination with elastic components such as under-rail pads or insulators, it enhances vibration absorption and noise reduction—an essential factor for metro systems operating in urban environments. The plate’s strong mechanical performance and corrosion-resistant coating ensure reliable operation even in underground tunnels, humid climates, or areas with chemical exposure.

The Metro Iron Base Plate is widely used in metro lines, light rail systems, urban transit networks, and depot tracks, supporting both ballasted and ballastless track structures. It is compatible with various fastening assemblies including WJ-7, WJ-8, and WJ-9 systems, and can be tailored to meet different rail profiles and sleeper materials. Installation is simple and efficient, requiring minimal maintenance and enabling easy inspection and replacement during routine track servicing.

Complying with international railway standards such as UIC, AREMA, and EN, the Metro Iron Base Plate can be customized in size, thickness, hole configuration, and surface treatment to suit specific design and operational requirements. Environmentally friendly coating technologies and recyclable materials make it a sustainable choice for long-term metro infrastructure development.

In summary, the Metro Iron Base Plate is a durable, precise, and high-performance component designed to meet the demanding needs of modern metro systems. Its excellent load-bearing capacity, corrosion resistance, and compatibility with multiple fastening systems ensure enhanced safety, reduced vibration, and extended track life—making it the preferred solution for reliable and efficient urban rail operation.
