Aluminum offers an excellent strength-to-weight ratio, which is crucial for rail transit to reduce energy consumption. It also provides natural corrosion resistance and allows for complex extruded cross-sections to guide door mechanisms smoothly.
Hard anodizing creates a much thicker and denser oxide layer on the aluminum surface. This provides exceptional wear resistance against the constant sliding friction of train doors, while the black color offers a clean, professional aesthetic.
