Semi-rigid vent duct customized retractable and bent pure aluminum

The structure of the aluminum semi-rigid vent duct will be stronger compared with traditional aluminum foil or PVC ventilation ducts, its appearance will be more exquisite. In many cases, it can be installed directly without additional wrapping.

The semi-rigid body makes it easier to install. There is no need for too many fixings during installation, which makes installation easier.

However, considering the semi-rigid vent duct characteristics, the required length and installation angle needs to be calculated in advance. The shrinkage ratio is 1:3, which can provide good installation support.

The pure aluminum structure can extend its service life.
