Sheet Metal - Overview

Sheet metal is simply metal formed into thin and flat pieces. In 1887, Robert Kellerstrass, secretary of the Tin and Cornice Makers Association of Peoria, Illinois—a local sheet metal workers’ union—began agitating for the formation of a national sheet metal workers’ union. The union was founded on January 25, 1888 in Toledo, Ohio, as the Tin, Sheet Iron and Cornice Workers’ International Association. A second Canadian local formed in Montreal  and a Vancouver local.
