Rectangular straight ducts are produced on a highly automated production line allowing ducts of all sizes to be made and guaranteeing final product high quality.
Longitudinal junctions for ducts are made using Pittsburgh-type seams. Duct manufacturing is in compliance with UNI 10381 standards.
The transverse flanges are directly part of the metal sheet of the duct, eliminating the need to have a profiled frame to be secured onto the duct. This technique provides better sealing against air leaks, in accordance with the current regulations, and increases mechanical resistance.
