Abstract

Ce grillage, du type en matière plastique, comporte, en combinaison, au moins un élément longitudinal de caractéristiques mécaniques telles que sa résistance à la rupture soit différente de celle du grillage lui-même, et au moins un élément métallique associé soit à cet élément longitudinal, soit au grillage.This mesh, of the plastic type, comprises, in combination, at least one longitudinal element with mechanical characteristics such that its breaking strength is different from that of the mesh itself, and at least one metal element associated with either this element. longitudinal, or to the wire mesh.
