Abstract: A reticular structure includes first elements distanced from each other and having an elongated conformation according to a first prevalent development trajectory, and second elements distanced from each other and having an elongated conformation according to a second prevalent development trajectory orthogonal, to the first prevalent development trajectory of the first elements. The first and second elements intersect at nodes to form meshes. The first elements have at a mid-portion defined between two consecutive nodes and orthogonally to the first prevalent development trajectory and a substantially T-shaped section including a base and a protuberance emerging orthogonally from the base.
