Roof or wall cladding comprises sheet metal panels with longitudinal ribs along longitudinal edges projecting perpendicularly upwards with head parts of rounded cross-section for interengagement

摘要

The individual sheet metal panels (3,4) have along their two longitudinal edges upwardly projecting longitudinal ribs (1, 2) with head parts (10, 9). The longitudinal ribs are set perpendicular to the plane of the panels and the head parts each have a partial circular shaped cross-sectional profile provided with radially directed holding means (12) and coupling means (11). the head part of the engaged rib can have an approximately semi-circular cross-sectional profile and a coupling means formed by a channel-like swage directed radially relative to same.
