Square ducts
Group I square steel pipes (hereinafter referred to as ducts) are air-conditioning ducts, used mainly for air conditioning and ventilation. The pipes are manufactured in parts made of double-sided galvanized sheet metal with a galvanizing layer of 275 g/m2. Requirements for different material quality are solved within an atypical design. The duct consists of pipes, fittings and accessories.
Fittings are typically arcs, knees, bounces, transitions, junctions, shaped and trouser pieces.
