Spiral ducting is usually joined using slip-fit connections, collars or flanged connections, then sealed and mechanically secured where required. The right method depends on duct diameter, pressure, leakage expectations, access and the fitting being connected.
Circular and rectangular ductwork both have important roles in commercial ventilation and HVAC systems. The right choice depends on airflow requirements, available space, pressure, installation constraints, access for maintenance and project budget. This guide compares their practical differences to help buyers, designers and installers select the most suitable ductwork format.
Galvanised spiral ducting is a circular sheet metal duct system widely used for commercial ventilation, air distribution and HVAC applications. This guide explains its construction, benefits, common applications, components and key specification considerations.
