Abstract
A welded wire panel, which can be used to make fences, is made of welded wires which have been cold-drawn into a noncircular cross sectional shape, the orientation of which varies helically along the length of the wire. Each such wire has cold-drawn characteristics substantially throughout its structure and over its whole surface. A first set of the wires extends vertically with adjacent wires spaced far enough apart to prevent a child from getting a foothold for climbing. The vertical wires are welded to horizontal cross wires, which are spaced far enough apart in the vertical direction to avoid giving a child a step for climbing the panel.
