Minneapolis, Minnesota has been the home base of our HVAC duct manufacturing and fabrication company since 1969. In that time, we have grown from our founder’s garage to a 250,000 square-foot technologically advanced fabrication facility. Having our Minneapolis yellow label union shop — as well as our secondary Rockford, Illinois location — enables us to be a leading manufacturer, fabricator, and supplier to HVAC distributors and contractors, as we are quickly able to transport our parts anywhere across the country.

Being centrally located in the Midwest provides perks to our customers, which include:

You May Have Seen Our Work

As Minneapolis-based commercial HVAC suppliers, we are thrilled when we can contribute to projects in our community. Located downtown, U.S. Bank Stadium is a Minneapolis icon. Prior to the stadium opening in 2016, Sheet Metal Connectors was hired to perform ductwork fabrication for all of the stadium’s spiral duct.

The stadium, home to the Minnesota Vikings, takes up approximately 1.75 million square feet and holds 73,000 people, so you can imagine how much sheet metal and ductwork was needed. For the project, we provided 2,500 feet of 84-inch spiral duct for the upper bowl running more than 200 feet above ground level. Custom wagon reinforcements, access doors, companion rings, E-Z flanges, register taps, and everything else we supplied was delivered to the stadium site already assembled, ready for our partner to install.
