A corrugated metal decking having alternating crests and troughs and a decking web disposed angularly out of the vertical, a plurality of linear indentations each extending across the decking web in a direction between the crest and trough walls, said indentations being disposed in a parallel array, the length of each indentation being less than the full width of the decking web but extending over a substantial major fraction of the web width, said indentations being provided in contiguous alternating inner and outer formed indentations substantially symmetrical about the web plane, the length of each indentation being in the range of 70% to 95% of the web width, said web being joined to the crest and trough walls by a radius bend, the indentation length being on the order of but less than the dimension a-2R, where a is the web width and R is the radius of the bend and said indentations do not extend into crest walls, trough walls or radius bends.
