Abstract (en)
The present invention refers to high resistance extruded panels and to the containers made with them. The panels realized by this technique demonstrate a satisfactory rigidity. Their internal structure is placed obliquely with respect to the plane of the panel forming a series of isosceles triangles having alternatively the base on one plane of the panel, and the vertex on that opposite, every pair of successive triangles also having an oblique common side. This structure is such that any portion of the panel contained by any two section parallel to each other and orthogonal to the direction of the extrusion behaves as a reticular beam, thus conferring on the panel characteristics of high resistance.
