The railway sector is moving more and more towards high-speed and high-passenger capacity carriages. The extruded case alone can also be a few tonnes lighter than an equivalent in steel. For this reason, in recent decades, aluminum has been conquering more and more components inside high-speed trains, Intercity and light rails. In the case of high-speed trains, the use of light metal per carriage is significantly higher. Colombo Alluminio supplies laminates and extrusions in alloys and physical states typical for the needs of railway carpentry and is able to support substantial annual needs even with staggered deliveries.
