    • A cladding sheet (31) has two marginal ribs respectively extending longitudinally of opposite longitudinal edge margins of the sheet and each having upwardly converging flanks merging with a crest, such that when in use an underlying marginal rib (34) extending along one edge margin of the cladding sheet is overlapped by an overlying marginal rib (35) extending along the opposite edge margin of an identical sheet (31) and the sheets are secured with those edge margins in overlapping relationship by a hold-down fastener (36) extending through the crests of the overlapping marginal ribs, and is characterised by spacer means (37) associated with at least one of the marginal ribs (34), which spacer means ensure that there is a longitudinally extending barrier space (38) between the overlapping marginal ribs whereby any free water on the upper surfaces of the sheets that may be drawn between the overlapping edge margins by capillary attraction is inhibited from reaching the hold-down fastener.
    • 包覆片(31)具有分别在片材的相对的纵向边缘边缘纵向延伸的两个边缘肋条,并且每个具有向上收敛的边缘与峰顶合并,使得当使用时,下面的边缘肋条(34)沿着 覆层片由沿相同片材(31)的相对边缘延伸的上覆边缘肋(35)重叠,并且片材通过延伸穿过所述片材(31)的压紧紧固件(36)以重叠关系被所述边缘边缘固定 重叠的边缘肋的顶部,并且其特征在于与至少一个边缘肋(34)相关联的间隔件装置(37),该间隔件确保在重叠的边缘肋之间存在纵向延伸的阻挡空间(38),由此 通过毛细吸引可以在重叠的边缘之间拉伸的片材的上表面上的任何自由水被阻止到达紧固 呃。
