Our ovalizer can fabricate up to 36” diameter on the minor axis of ductwork. As with the other division of ductwork, we assemble all of the ductwork in our facilities, so there’s no need for job-site assembly of ductwork.

Ductwork will be welded if it is required based on SMACNA standards. To make it simple, when our ductwork leaves our shop, the ductwork is ready to be installed.

DN Duct Solution provides single and double wall flat-oval ductwork both with a slip-fit and a flanged connection. Our flat oval duct and fittings are manufactured in material thicknesses from 24-16 gauge galvanized steel, as required to meet SMACNA and ASHRAE standards, based on flat oval major axis dimension.
