History & Mission

Sheet metal work dates back centuries, including its use in early home construction.  It became critical for environmental control during the Industrial Revolution with the advent of heating, ventilation and air conditioning (HVAC) systems that maintain a comfortable air temperature and pressure, as well as provide air filtration. SMACNA International was founded in 1943, and SMACNA St. Louis began shortly after in the 1950s.
