Why Double-Flange Railway Wheels?

The problem: On steep gradients and tight curves, standard railway wheels are prone to derailment, rapid flange wear, and reduced stability under heavy loads. So our solution: Double-flange Railway wheels provide extra guidance on both sides of the rail, significantly reducing derailment risk while extending wheel life — even in the toughest conditions.

Product of Double-Flange Railway Wheels Overview

Our double-flange heavy-duty railway wheels are designed for the most demanding rail applications. Built to carry extreme loads while maintaining stability, these wheels are the ideal solution for:

Mining operations
Industrial railways
Heavy freight transport
Ports and cargo terminals

Unlike standard railway wheels, the double-flange design offers extra guidance on tracks, minimizing derailment risks — particularly in tight curves or on steep gradients.

Manufactured from premium alloy steel, these wheels combine high tensile strength, exceptional wear resistance, and precision machining to ensure smooth operation and minimal maintenance over years of service.

Performance and Design

Every wheel is heat-treated to achieve optimal hardness, balancing durability and toughness. Our production process strictly controls dimensions and tolerances, providing wheels that fit perfectly on your rail system.

Material options: Our alloy steel choices, including 20MnCr5 and 25CrMo4, offer the strength and toughness required for heavy-duty operations.

Typical performance:

Tensile strength: 800 – 1000 MPa
Hardness: 280 – 320 HB

Result: long-lasting performance even under continuous heavy loads.
