A structural steel decking panel is disclosed, the panel for supporting construction loads and materials including wet concrete and subsequently longitudinally reinforcing the concrete after it has hardened. The panel (10) includes: a first longitudinally extending rib (20); a second longitudinally extending rib (40) spaced apart from and parallel to the first rib (20); and an elongate pan (30) joining the first and second ribs (20, 40) and forming a base, each rib having a top portion (45) and a pair of web portions 44, the web portions (44) diverging as they extend down from the top portion (45) to the base, characterised in that the ribs have a fold zone at an end, whereby the top portion (47) slopes downwards towards the base and the web portions (44') are folded such that in part they form part of a Z-fold that lies adjacent and substantially within or parallel to a transverse inclined fold plane.
