of section or any length the orientation of the sharp points with respect to the mesh can be perpendicular oblique or any other the sharp points can be straight or curved individual or multiple single or braided or of any other type the manufacturing process of the mesh will be by electrowelding such that a flat rigid or semirigid mesh is obtained that is barbed the mesh will be produced in sheets of any size the sheets can have any distribution of squares of the mesh with respect to its edges which can have any type of finish in this fashion the sclerophyllic mesh offers the advantages of normal metallic material of the rigid or semirigid type which because it has a certain hole size prevents the livestock from sticking their heads through and eating the tree and the barbed wire which because it is barbed prevents the livestock from rubbing against it and knocking over the cage or breaking it although the main use foreseen for the mesh is the one presented above other possible uses are not discarded such as pastoral farming industrial or urban uses fig1 shows a view of an example of an embodiment of the esclerofila mesh.
