A paperboard panel substitute for lumber, particularly adapted for use as a skid for supporting an object, comprises a plurality of layers of corrugated paperboard forming an inner core, and an outer jacket of solid fiber paperboard enveloping the core and secured thereto. The solid fiber jacket is formed by folding a sheet thereof about the core and adhesively bonding the same thereto. For use as a supporting skid, the panel is pre-formed with an apertured portion to receive a fastening member adapted to be secured to an object to be supported. Such apertured portion includes a knockout section which is displaced by a head on the fastening member to form a countersunk recess and a washer therefor.
