Abstract
A structural load-bearing portable panel for staging, choral risers and the like having a high impact corner construction to resist the shock and dragging forces to which the corners are subjected when being assembled, disassembled, transported and stored. A molded or extruded corner element interfits with and is retained mechanically by the side edge pieces which have a recess to receive wing extensions on the corner elements. The corner elements are backed by the core material in the panel which is a lamination of surface elements and coring reinforcement. Each corner element can have a recess normal to the plane of the panel to receive structural support legs or the like.
