This invention discloses a cargo container (10) with transparent polycarbonate panels (12, 14, 16) held by inner and outer corner molding strips (18, 24). The molding strips (18, 24) are press-fitted together, form the corner joints (20) of the container (10), and retain the panel edge corrugations (29, 30) by internesting the corrugations in a matching channel (19, 25) formed by the mated strips (18, 24). The panel (12, 14, 16), therefore, is not penetrated by bolts, rivets, etc. The invention also discloses a method to progressively shape-form corrugations into preheated (to 120 DEG F) panels by a series of roller dies, some of which are also heated to 110 DEG F. |
