The test is carried out in order to make clear the mechanical properties of the structural welded wire fabric with variables such as tensile strength, reduction of area, elongation, welding point shear strength and bendability. The results are as follows: 1) The test piece across the welds about tensile strength is slightly higher than between the welds, and the elongation is opposite. 2) Welding point shear strength is considerably high, but if the strength is much increased, tensile strength get low by brittleness of welding point. Accordingly it is necessary to establish the shear strength as $15kgf/mm^2$($150N/mm^2$). 3) The bend test should be carried out at welding point, the ductility of which is the smallest.
