AbstractSheet metal has been and still is by far the most common material used in the fabrication of ducts for the handling of air in heating and ventilating systems. Other non-combustible materials such as concrete, asbestos-cement, and ceramic tile which compete successfully with metal for some fluid piping applications have been used to a limited extent in duct construction.They may have advantages over metal in special cases, notably where corrosion is an important consideration.
