DN Duct Solution fabricates single wall and double wall rectangular ductwork. Rectangular ductwork is manufactured using 26-18G galvanized steel and all of the ductwork is assembled. In addition to the roll-formed ductwork, we can fabricate welded rectangular ductwork using 16 gauge galvanized steel, black iron, and stainless steel ductwork.

Our company fabricates the ductwork based on the latest SMACNA standards. Internally insulated ductwork is completed using different fiberglass or foam liner thickness: ½”,1”,1.5”,2”. We also have the ability to fabricate double wall ductwork using a perforated or solid inner wall using any size liner thickness based on the project’s specifications.

We have the latest technologies from plasma tables, liner cutting tables, and a full coil line in our rectangular ductwork division to fabricate and deliver the ductwork in the least amount of time.
