Flanges of strip rolling for air ducts.

Round flanges are used to connect air ducts to each other and to shaped products. On the circumference of the flange are mounting holes, the number of which depends on the diameter of the flange. At the request of the customer, the number of punching holes at the flange can be made larger by the number than described in the standard. Such a change will ensure a more dense and hermetic connection of the flanges and ducts.

Flanges are suitable for galvanized and welded air ducts and provide a reliable connection without gaps and protrusions. Most often, the connection of air ducts with flanges is used for the installation of smoke, aspiration and pneumatic transport systems. With the help of flanges, it is possible to quickly obtain sections of air ducts of the required length.

The flanges of our company are of high quality and reliability, manufactured in accordance with standarts and in accordance with your needs.
