ABSTRACT:
A structural member is an elongated, generally rectangular panel having at least 2 substantially parallel fold lines extending the length of the panel parallel its long sides, preferably defining 3 subpanels. When the panel is folded along the fold lines, preferably by hand, the interior angles at each fold occur on the same surface of the panel, are approximately 90 degrees, and the member has a generally C-shaped cross-section when folded. At least one male/female lock holds each of the panels at a fixed angle relative to the adjacent panel, each male/female lock having a male component affixed to one of the subpanels and a mating female component affixed to the adjacent subpanel such that when said one subpanel is folded with respect to the adjacent subpanel, the male component inserts into the female component and is retained therein.
