Aluminum flange and corner

For some applications, ductwork and connection materials made of aluminium are the first choice. This might be the case when, in addition to a certain level of stability, the lowest possible weight of the components is also of great importance.

In order to be able to produce sealed ducts in the usual way, Gebhardt-Stahl offers you flanges made of aluminium, as well as the matching corners.
