Abstract
Triple-twist and fourth-twist model hexagonal wire mesh panels were weaved for
tensile and punch tests. The test samples consisted of unbroken wire mesh panels and one central cut
wire mesh panels. The binding-joint and twist-joint for the connection of wire mesh panels were also
evaluated. The results of the experiments indicated the ultimate tensile strength or punch resistance
for triple-twist or fourth-twist hexagonal wire mesh panels was similar. As the test reached the peak
tensile force and after one steel wire broke, the tensile force was quickly reduced and the elongation
rapidly increased for the triple-twist hexagonal wire mesh. Similar results were also observed for
punch tests for triple-twist wire mesh. However, the fourth-twist hexagonal wire panels showed higher
tensile and punch resistance after the wire was broken at the center or other locations. In addition,
twist- joint enables the provision of higher tensile resistance than for binding joint.
