A corrugated metal decking having alternating crests and troughs and interconnecting therebetween a decking web that is characterized by improved stiffening means, in particular in the form of embossments or indentations. There are provided a plurality of linear indentations, each extending across the decking web between the crest and trough walls. These indentations include inner and outer formed indentations, formed symmetrically about the web center plane with the length of each indentation being in the range of 70%-90% of the web cross-dimension and with the indentations being closely spaced. This arrangement provides for superior web stiffening and also provides improved composite action for interlocking between the metal decking and the concrete.
