A profiled deck is roll-formed from a steel sheet to define at least one pair of crests 2, a stiffener 16 upstanding from the surface of each crest, a trough 6 positioned between the or each pair of crests, and inclined webs 8 extending between the sides of the trough and the neighbouring sides of the crests. The boundary between each web and crest defines a corner 14 which has a smooth curvilinear profile. The elemental compression width of each crest 2 is no more than four times the elemental compression width of the respective stiffener 16, and the radius of each curvilinear corner 14 is not less than 33mm.
