Abstract
An extruded plastics mesh having two sets of oblique strands lying in adjacent planes and joined together at their crossing points by tenacious intersections is suitably stretched to form a structure having mesh openings each of which is a six-sided figure bounded on four sides by portions of four separate strands and on the other two sides by strandlike members comprising stretched intersections of the original mesh. To inhibit splitting of the structure along the length of the stretched intersections there is provided at opposite ends of each such intersection a relaxed web integral with the structure and extending across the crotch defined by the two strands which form the intersection.
