<p>In order to produce high tensile strength mesh structures, starting material, which is at least 0.75 mm thick and which has a square or rectangular pattern of holes or depressions, is stretched either in one direction or in two directions at right angles. The uniaxially stretched structure has orientated strands which are connected by parallel bars, the orientation of the strands penetrating into the bars but the centers of the bars being thicker than the strands, all along the length of the bar center. The biaxially stretched structure has orientated strands which are interconnected by orientated junctions which have orientated crotches between the strands; the thinnest parts of the junctions are not less than 75% of the thickness of the strands, the thickest parts of the junctions are thicker than the thinnest parts and thicker than the strands, and the center of the junction is not the thinnest part of the junction.</p> |
