With the rapid development of urban transportation, the subway has become one of the most important modes of public transport in large cities. As lightweight, durable, and corrosion-resistant materials are increasingly required in this field, aluminum profiles have become the ideal solution for subway manufacturing.

1. Lightweight Structure for Energy Efficiency

Compared to traditional steel materials, aluminum profiles are significantly lighter. This feature reduces the overall weight of subway cars, which leads to improved energy efficiency, lower operational costs, and reduced wear on rails.

2. High Strength and Structural Integrity

Thanks to the advanced alloy formulations and precise extrusion techniques, aluminum profiles used in subways offer high mechanical strength. This ensures safety and durability even under frequent, high-speed operation and vibration.

3. Excellent Corrosion Resistance

Aluminum naturally forms an oxide layer that protects it from corrosion. For subway environments with high humidity or air pollution, this is especially important to extend service life and reduce maintenance needs.

4. Wide Applications in Subway Systems

Aluminum profiles are used in various parts of subway systems, including:

1.Car body frames: Reducing weight while ensuring structural strength

2.Doors and windows: Providing precision, aesthetic appearance, and corrosion resistance

3.Interior trims: Offering modern design, easy maintenance, and comfort

4.Equipment housings and support structures: Durable and safe for high-stress environments

5. Customized Extrusion Solutions

Modern subway projects often require tailor-made aluminum profiles. Our factory supports custom extrusions up to 9 meters in length using a 15,000-ton press, which allows for large, integrated structural parts to be formed in one piece, reducing assembly and improving integrity.

6. Global Applications

Our aluminum profiles have been successfully applied in several metro projects across Asia and Europe. For example, a German metro system adopted our large aluminum structural profiles to improve strength while reducing assembly time.
