ABSTRACT:
A coated steel roof cladding panel comprises upwardly projecting, inverted channel, edge and stiffening ribs with essentially flat pans between the ribs. At or near each junction of a rib and panel there is a small bead extending in the same direction as the ribs, and projecting downwardly. If the panel is walked upon after or while being laid on supporting purlins, the beads deform sacrifically and prevent unsightly transverse marks forming in the pans due to flexing of the panel.
