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