<p>The wire grid has a steel core provided with a coating that is made from alloy of zinc and aluminum. The alloy has a zinc proportion ranging between 91 and 98 percentages by weight, aluminum proportion between 5 and 1 percentages by weight and magnesium proportion ranging between 0.1 and 4 percentages by weight. The wires (1, 2) have a diameter ranging between 3.5 and 6 millimeters. The alloy is applied on the steel core in plating between 250 and 450 gram per meter square, and the coating has a thickness ranging between 35 and 65 micrometer.</p> |
