How thick should the substructure elements be for metal siding on a 7-meter-high house?
So that the structure does not sag under the weight of the siding. I mean thick enough. (I understand that the thicker the better).
1) The suspension? 0.65, 0.80 or 1.00 m?
2) Profile? 0.5 or 0.65 mm?
There is no economy to put the facade on profiles and hangers that are not designed for it.
Take a standard galvanized sub-system!!!
