Abstract
A walkway on a rooftop comprises expanded metal planks supported by U-shaped support stands disposed transversely with respect to the length of the planks. The planks have alternating rows of ridges and valleys, both of which have transverse slits. The planks are connected to the support stands by T-shaped bolts whose crossbars are rounded. The shanks of the T-bolts pass through the slits in the valleys and the crossbars nestle within the valleys in rotatably slidable engagement with the metal.
