Claim:
A cladding assembly that includes: (a) a plurality of concealed clips secured to an underlying structure; and (b) a plurality of cladding sheets that have enhanced uplift capacity and are in side by side overlapping relationship and are retained on the underlying structure by the concealed clips, each cladding sheet including side formations on opposite sides of the sheet that engage complementary side formations on adjacent sheets and retain the sheets in side by side overlapping relationship, each cladding sheet also including at least one lengthwise extending pan and a lengthwise extending rib on each side of the pan, with each rib having a width of between 70% and 130% of the width of the pan, and wherein one side formation includes a re-entrant section that engages one concealed clip and a channel that opens inwardly of the sheet and is in a higher section of the one side formation, and wherein the other side formation forms one side of one rib and includes an in-turned lip that extends into the channel of the one side formation of an adjacent sheet, wherein the other side of the one rib includes a re-entrant section that engages one concealed clip, and the engagement of this side of the one rib with the re-entrant section ensures that the in-turned lip extends into the channel and retains together the side formations and holds the adjacent sheets in overlapping relationship.
