An improved structure for transporting on a semi-trailer large sheets of flat rigid material such as large sheets of flat glass. A generally A-shaped platform having sloped sides is secured over a conventional semitrailer frame. Stacks of the material being transported rest on a plurality of rigid girders which project outwardly from the lower edges of the sloped sides. A novel clamping mechanism is adjustable to engage both edges and the side of each material stack during transport and is removable to facilitate loading and unloading the trailer.
