NQ Pipe & Duct have been supplying duct and piping systems throughout North Queensland since 2009


We handle specialised pipe and duct systems

NQ Pipe & Duct offer duct and pipe solutions for a vast range of applications in the construction, engineering, airflow ventilation, mining and agricultural industries. Our products can often be used to replace inherent systems much more efficiently and cost effectively. In particular our stainless steel spiral welded pipe and our PolySpiral products have offered a lighter weight, longer wear life and less expensive option than has previously been used or available in their respective industries. The ability to provide a large diameter pipe from a lighter wall material and to exact lengths offers savings in weight, wastage, fabrication and installation time. Very few of our products are stocked due to the enormous range of sizing variables available. We offer a full range of duct and tube diameters but also the full range of pipe diameters to easily adapt to existing systems. All our systems are made to order but are readily available with manufacture and delivery usually taking just a few weeks. Please refer to our sizing charts for the various options for spiral lockseam duct, oval duct and spiral welded pipe/tube.
