Body & Chassis Structures

Roof header materials must have high tensile strength and lightweight to lower the vehicle center of gravity.  Toughness is important, as is integration capability. A commonly utilized alloy utilized is 6082 aluminum, a which delivers strength, toughness, extrudability – and that converts multiple steel stampings to an efficient, one-piece extrusion on Ford’s flagship vehicle, the F-150.

The weight savings is real, and significant: The roof header on the Ford F-150 delivers 2.9 kg weight savings! 

Extruded roof headers, bows, and rails play a key role in the protection of the passenger compartment on the F-150, which is one of the world's top-selling vehicles.

Success Stories 
 

Metrics to Success in Roof Header Extrusions:

  • Tight tolerances
  • Controlled grain structure
  • Straightness (Profile Tolerances)
  • Stringent mechanical property requirements
  • Versatile to various assembly techniques
