Square to Round Patterns
Note that this product is for a pattern only. The pattern itself may be formed by the purchaser, or it can be used a template to produce additional square to rounds. We will cut out the square to round required on a CNC cutting machine but it will be supplied as a flat sheet steel pattern in two halves (square to rounds are commonly made in two halves). The square to round will not be formed or fixed by us. It is assumed that the purchaser is familiar with the method used to form the piece. If you require the finished piece, i.e. fully formed and fixed please see:
Square to rounds.
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.
