Why this ducting earns its place
Kitchen extraction systems move heat, moisture, and cooking vapours from the cooking line to the roof and out of the building. Unlike round ducting, square pipes offer practical advantages when space is tight or when you're routing around obstacles in the kitchen or ceiling void. The 250 mm square section is compact enough to fit above or beside standard preparation and cooking equipment, yet capable of handling the airflow demands of a working kitchen.
Aluminium construction keeps weight down — this 250 mm section weighs just 2 kg — making it straightforward to handle, position, and secure during installation. Aluminium doesn't corrode under the conditions extract air creates (heat, moisture, acidic vapours from cooking), and it won't harbour bacteria or odours that can develop in other materials over time. The rigid, modular design means you can assemble a complete ducting run by connecting sections with standard fittings and clamps.
Fit-out contractors and kitchen designers commonly use square ducting when routing over doorways, into tight ceiling spaces, or alongside other building services. Each section connects cleanly with others and with transition boxes where you need to change size or direction.
