About Us

Conklin Metal Industries is a distributor of all types of sheet metal, HVAC and duct fabrication supplies.  Our founding dates back to 1874, and is now in its fourth generation as a family owned and operated business.

We service the entire southeastern U.S. out of fourteen (14) warehouses. Our customers include sheet metal contractors, mechanical contractors, duct fabricators, residential\multi-family new construction contractors, and HVAC contractors who specialize in service and replacements.

We are a one stop shop for every component used in the construction and installation of a commercial or residential HVAC Duct system. This includes the sheet metal for the rectangular or spiral/round duct, plus all of the materials to connect, fasten, insulate, attenuate sound, control vibration, reinforce, direct air flow, provide access, and ultimately hang and seal. We also stock the most wide array of sheet metal forming machinery in the southeast. 

Our new Plan & Spec Division is based in Memphis and provides quotations directly from prints on commercial projects.
