Abstract: A wire-mesh security fence panel and security fence is provided. In at least on example the fence panel includes: a first set of substantially parallel wires, each wire having a first and a second end; a second set of substantially parallel wires, the second set of wires being welded across the first set on one picket-wire side of the first set; a cross-wire-side connection strip welded across the first end of the first set on the picket-wire side of the first set; and an opposite side connection strip welded across the second end of the first set on the opposite side of the picket-wire side. In one such example each connection strip has an outside edge and each outside edge is equally spaced from the end of the wires to which the strip is welded.
