Hardfacing overlay ductwork square to rounds, as the name suggests, convert square or rectangular ductwork to round wherever such a transition is required. This may be to connect rectangular ductwork to ventilation equipment designed for a circular connection, or to change the duct shape to pass through a confined space. In confined areas such as ceiling voids (the space between the suspended and structural ceiling of a building) it's common to see ductwork runs comprised of both rectangular and round spiral duct - the main duct and branches are rectangular as the equivalent sized round duct may not fit into the ceiling void. Square to rounds provide the means to make this transition.
