Blue car with aluminum roofrails


Anodizing process; increases corrosion and chemical resistance enhances wear resistance and improves the appearance of aluminum surfaces

From roof rails, trims, frames, electronic housing, brake calipers, and heat sinks as used in combustion, hybrid, and fully electrical vehicles, we partner with you to understand the specific requirements of each project to deliver the industry’s most functional and protective coating.

SUVs and aluminum

Vehicles are mostly sold on content, it’s a consumer product. At the moment the SUVs are immensely popular vehicles. These larger cars require additional lightweight considerations when compared to smaller cars.

For SUVs and pick-ups, there is a trend towards using aluminum brake calipers instead of cast iron. The aluminum brake calipers are often anodized to provide additional corrosion and wear resistance as well as uniform color (red, black, yellow, blue) to meet automotive specifications.


Anodizing aluminum extrusions for car exteriors creates a dirt-repellent surface and improves corrosion resistance. It provides a surface with electrically insulated coating and is available in different colors.

High-end aluminum exterior components for the roof rails, frames and trims are growing more popular as they provide a lightweight smooth surface that is pleasant to the touch.
