Dampa is one of the special structures that is used to cover the false roof as well as the gable roof, which in addition to its beauty, prevents wind from entering under the roof. Rivets or welds are used to connect the damper to the desired location and it has different thicknesses. Usually, this structure is ordered in thicknesses of 0.4 to 1.25 mm, and galvanized sheet, colored galvanized sheet, aluminum and oil sheet can be used to produce dampa. To produce Dampa sheet, two industrial and traditional methods are used. In traditional methods, this process is done using press machines, and different designs can be implemented on the sheet with this machine, which is accompanied by a length limit and It also slows down production. But in the industrial method, the sheets of this structure are made by using colored sheets with different patterns and designs in the form of longitudinal rolls, in which the sheets are produced more quickly and the sheet thickness is zero.
