<p>Specific profile for producing a horizontal metallic cladding, of the type comprising a plurality of identical horizontal ribs (1, 2, 3, 4) of trapezoidal section, each section being connected to the next one or to the preceding one by means of a vertical plate (5, 6, 7, 8, 9), characterised in that the upwardly directed short side of the trapezoidal section of the cladding forms, together with the adjacent upper plate (5, 6, 7, 8), an open angle alpha lying between 110 and 160 DEG , the downwardly directed short side (14, 15, 16, 17) of the trapezoidal section of the cladding forming, together with the adjacent lower plate (6, 7, 8, 9), an open angle beta lying between 90 DEG and alpha . <IMAGE></p> |
