Material Sizes

Wire and flat strip are produced in a range of standard sizes. Wire diameters and flat strip thicknesses usually stick to the Standard Wire Gauge (swg) sizes or to a metric or imperial size. Our wire stocks cover all the standard wire gauges and a lot of non-standard metric and imperial sizes for special cases.
