Description
Aluminium Invisible Flange 20mm
This piece is used to connect pre-insulated duct to each other. 20mm aluminum flange is used for sheets with a thickness of 21 mm. This flange is similar to PVC flange in terms of appearance and function, but when the implementation of the channel in sensitive projects in terms of air quality is important, aluminum flanges are used, because the resistance of these flanges to heat and cold is high. And in sanitary places where duct cleaning is often important, the use of these flanges is more appropriate.
Thickness: 20
