A cargo trailer wall structure of panels includes adjacent outer sheets, posts spaced along one side of the outer sheets and fasteners therebetween. The posts are formed into central webs and attachment ribs to either side of the central webs. The attachment ribs have concave surfaces abutting against the outer sheets and rows of holes matching rows of holes in the outer sheets. The elongate concave surfaces are aligned with the rows of holes of the attachment ribs. The fasteners draw the sheets and posts together and distort the outer sheets into contact against the concave surfaces.
