A metal scaffolding board comprises a rectangular sheet 1 having, over substantially its entire area, holes 5 with upwardly (or downwardly) directed rims. Flanges 2, with turned in edges forming box sections 21 are provided along the sides of the sheet 1. To stiffen the panel, and minimise the possibility of it deforming, members 142 are provided at each end of the panel to form a frame with the flanges 2. Claws 14 for locating the panel on a supporting framework are fixed to the members 142. In the illustrated case, the members 142 are U-section with their flanges 142' directed inwardly of that panel, but they could, if desired, be of box section. <IMAGE> |
