Rectangular Ducting/ Square Ducting is produced using an automatic machinenary that is able to create Transverse Duct Flange (TDF). By using TDF, leaks can be reduced and installations will be easier and more economical. This is because each process of connecting rectangular/square ducts uses TDF Corner, not just any other rectangular metal connectors.
