1. A decking comprising a unitary panel of uniform thickness sheet metal with a top surface and a bottom surface having a repeating pattern of top flanges and bottom flanges connected by webs therebetween wherein each of the top flanges and the bottom flanges each has a maximum energy potential and a width and the width of at least one of the top flanges is less than the width of at least one of the bottom flanges, the at least one of the bottom flanges connected to the at least one of the top flanges by a web, wherein the at least one of the top flanges is comprised of a plurality of folded-layer segments which are folded back onto itself to contact itself and adjacent to each other in a parallel stacked position, such that the maximum energy potential of the at least one of the top flanges comprised of a plurality of folded-layer segments is equal in magnitude to the maximum energy potential of the at least one of the bottom flanges without a plurality of folded-layer segments that is connected to the at least one of the top flanges by a web.
