Rectangular ducts are fitted with DEVO Flange Frames (20 / 30 / 40) manufactured from galvanized steel. These frames provide a strong and reliable method for connecting air duct sections.

Flanges are typically welded, clinched, or fixed using screws or rivets, depending on project requirements. Flanged joints are assembled by bolting two flange frames together with a gasket in between, ensuring a rigid, airtight, and secure connection.
