Made of stainless steel sheet or aluminum foil or copper sheet or galvanized steel sheet, of rectangular cross-section of any size, flanged. In various millimeters and dimensions, all constructions are on request according to the requirements of each project. The innovation of our company is that the flange used for the longitudinal connection is formed from the beginning, on the steel sheet, as a result of which there is a greater sealing in the network.
When building the rectangular air duct, our main feature is that the process is fully automated on the production line. Specifically, we place the raw material, which is in a roll at the beginning of the production line and at the end of the process we receive the airway ready. The human factor does not intervene in the whole process, therefore the time when the final product is produced is minimal and the case of any technical error is excluded, with the consequence that the produced material always has the same quality.
