A coating cover with a metal structure for roofs of buildings, comprising a plurality of slabs of substantially quadrilateral shape each of which is provided with the lateral edges (17,18) that are parallel to one another and opposite and are intended for mutual connection between adjacent slabs in the longitudinal direction and are intended for the formation of a joint positioned between each of the adjacent slabs, wherein said lateral edges (17, 18) comprise first folds (18a,18b,19a,19b,20a,20b,21a,21b,22a,22b,23a,23b) at least partially symmetrical on the two edges, and moreover further folds (24,25,26) made on at least one of the lateral edges, and still further folds (27,28) made on at least the other of the lateral edges and configured to interlock with said further folds (24,25,26), said cover further comprising at least one fixing bracket that is configured to join the lateral edges (17,18); said fixing bracket having at least two recesses (15,16) that are symmetrical to one another and indentations (15a, 16a) that are symmetrical to one another, the recesses (15,16) of the fixing bracket being defined respectively by two portions (15',16') projecting upwards and then folded partially downwards in the direction of the space comprised between the recesses (15,16) themselves forming horizontal portions, wherein said lateral edges (17,18) comprise at least one curvature defined by some first folds (20a,20b) that overlies some other first folds (21a,21b) so as to accommodate at least one of said horizontal portions of the fixing bracket, wherein said recesses (15,16) of the fixing bracket extend along a horizontal direction parallel to a flat base of said bracket, characterised in that the folding of the two horizontal portions (15a, 16a) defines said indentations (15',16') that extend upwards, and in that the indentations (15a, 16a) of said recesses (15,16) house said at least one curvature formed by the other first folds (21a,21b) placed respectively to the lateral edges (17,18) of the slabs in order to compensate for a rotation caused by stress due to wind-uplift. wherein said lateral edges (17, 18) comprise first folds (18a,18b,19a,19b,20a,20b,21a,21b,22a,22b,23a,23b) at least partially symmetrical on the two edges, and moreover further folds (24,25,26) made on at least one of the lateral edges, and still further folds (27,28) made on at least the other of the lateral edges and configured to interlock with said further folds (24,25,26), said cover further comprising at least one fixing bracket that is configured to join the lateral edges (17,18); said fixing bracket having at least two recesses (15,16) that are symmetrical to one another and indentations (15a, 16a) that are symmetrical to one another, the recesses (15,16) of the fixing bracket being defined respectively by two portions (15',16') projecting upwards and then folded partially downwards in the direction of the space comprised between the recesses (15,16) themselves forming horizontal portions, wherein said lateral edges (17,18) comprise at least one curvature defined by some first folds (20a,20b) that overlies some other first folds (21a,21b) so as to accommodate at least one of said horizontal portions of the fixing bracket, wherein said recesses (15,16) of the fixing bracket extend along a horizontal direction parallel to a flat base of said bracket, characterised in that the folding of the two horizontal portions (15a, 16a) defines said indentations (15',16') that extend upwards, and in that the indentations (15a, 16a) of said recesses (15,16) house said at least one curvature formed by the other first folds (21a,21b) placed respectively to the lateral edges (17,18) of the slabs in order to compensate for a rotation caused by stress due to wind-uplift.
