New corrugated cardboard of the covered type, characterized essentially by being made of flat sheets of material, color and appropriate dimensions, between which a third sheet of the same nature appears, corrugated and arranged with its channels, which are fixed to the elements external by means of a glue applied to the crests of those, oblique with respect to any of the axes of symmetry of the piece of cardboard, in order that such orientation, never equivalent to a ninety degree angle, confers to the whole a high resistance to bending.
