A panel structure having a low-density core that can withstanding loads normal to a first primary surface, and a first facing of high-density sheet material that can extend along the first primary surface. The high-density sheet material can be laminated on the core such that the laminated core and facing cooperatively resist bending loads and loads along the primary surface. The first facing can extend from the first primary surface on a side of the core along a secondary surface, which can be non-parallel to the first primary surface. The first facing can bend along a score line between the first primary surface and the secondary surface.
