Abstract

See full text

A metallic extruded profile has two parallel skins interconnected by a set of at least two webs running between extrusion edges of the profile and snap-fit features on joining edges permitting two instances of the profile to snap fit together along the joining edges, where a first web that is closest to snap-fit features of a first joining edge, is a curved web viewed from the extrusion edges. The curvature allows for both the curved web and skins to participate in snap-fit deformation, allowing for the deformation to be distributed over a large area, for a stiffer snap fit, and reduced plastic deformation.
