Ventilation systems with rectangular cross section have many uses, including as: ventilation systems, carried out inside the walls of cardboard-plaster plates, the air inlet systems for burning in fireplaces, systems distributing warm air from fireplaces, etc.
Ventilation elements are made of galvanized steel sheet with a thickness of 0.5 mm, in two-dimensional versions: 50 x 150 mm and 90 x 200 mm. All components are made using a spot welding technology. The variety of shapes allows us to build very complex systems.
The system is mounted to the wall with a rectangular mounting bracket. Connecting the various components takes place through an internal connector. The system does not require additional sealants or paste.
