<p>The post has recesses (1) for positioning racks, longerons or gondola elements at different heights, where the post is made of plastic material or metal sheet. Complete longitudinal folds (3, 4) are formed on a face of the post, where the post does not include an opening along its height except the recesses. A closed perimeter section (2) is provided in a polygonal form outside a folded zone that is positioned in middle of the post face. A linear portion between the folds is positioned inside the post with respect to a square or rectangular structure of the closed perimeter section.</p> |
