A sheet metal shop is a must for quality control and timely delivery.  For quality fitted duct, your best bet is a CNC plasma system.  We have two CNC plasma cutters and a 5 foot coil line to make the ductwork fit the schedule.  We use a flanged duct connector called TDF for a stonger and more leak free duct system.  The bolt together duct connector and gasket joint allow for faster jobsite installation.

Our plasma cutters can make roof curb adapters fit obsolete roof curbs for installation of new roof top units.  Roof curb adapters can be made in just a few days.

Kitchen welded grease duct can be measured cut and welded faster when all of processes are under one roof.

For budget consious projects we offer fiberglass ductboard.  We cut and assemble in our shop to speed onsite installation.
