Customized automotive roof rails and decorative trims

With an extensive network of production sites and wide selection of services, we can provide you with design support and extrusion all the way through to the final manufacturing stages for aluminium roof rails, exterior trims and decorative trims.

Aluminium roof rail and decorative trim

Aluminium as a material choice meets a range of performance and sustainability benefits when used in automotive designs, with some applications more suitable than others, such as roof rails and decorative trims. These applications, both interior and exterior, go hand in hand with the properties of aluminium.

We offer bespoke aluminium extrusion from our dedicated automotive presses, as well as an extensive list of additional services in-house, for a fully customized automotive application with full traceability.

Our European production sites are certified to ASI’s Performance and Chain of Custody Standards.
