Abstract
An extruded integral plastics net structure comprising first sets of spaced parallel strands, second sets of spaced parallel strands extending transversely thereto, the sets of strands being joined together at all or certain of their points of intersection to form a net structure wherein the intersection points along any one strand are in the alternating forms of any two of the following: (a) integral masses of mirror image symmetry about the median plane of the net, (b) assymetrical junctions in which there is substantially only linear contact and adhesion between the strands and (c) symmetrical junctions having only linear contact with little or no adhesion between the strands.
