<p>A sheet decking (1) has a plurality of parallel transversely spaced-apart re-entrant dovetail corrugations (2) extending longitudinally along the sheet (1). An upper section (4) of each corrugation has a plurality of spaced-apart upper shear keys (10). Side walls (5, 6) of the corrugations (2) have a plurality of spaced-apart side shear keys (11). The combination of the re-entrant dovetail corrugations (2) and the upper and side keys (10, 11) give an improved mechanical bond between the sheet decking and conctrete.</p> |
