Our Manufacturing  
About National Excelsior Company - Sheet Metal Duct Manufacturer and Distributor
 

Manufacturing with pride, our Brookfield, Missouri plant produces the highest quality sheet metal duct work and fittings.  We pay attention to details which makes us a preferred brand amongst installing HVAC contractors and home builders.  Finer points differentiating us from competitive manufacturers include using higher quality gauge metal, product selection, and the rolled over hemmed edge on our cross broke duct.  These elements were recently featured on the home improvement show Hometime.
