<p>A profiled castellated metal sheet has secondary features 4 surmounting its flat-topped areas 3 which run parallel to the castellations and which are upstanding from the flat-topped areas 3 in use and have a maximum open width of 25 mm. These secondary features 4 are used to support a mesh when the sheet is used as a decking for a composite steel/concrete floor, and avoid the need to support the mesh on separately provided mesh support stools. The use of such a castellated sheet therefore decreases both the time and cost involved in construction of such composite floors, and also increases the structural integrity of the floors so formed. <IMAGE></p> |
