Weight of 6 X 118 equals midway weight between 6 X 1% and 6 x 2.. WEIGHT OF IRON AND STEEL SHEETS. Weights per Square Foot. (For weights by Decimal Gauge, see page 32.) As there are many gauges in use differing from each other, and even the thicknesses of a certain specified gauge, as the Birmingham, are not assumed The same by all manufacturers, orders for sheets and wires should always ate the weight per square foot, or the thickness in thousandths of an inch.
