Unions

Sheet Metal Workers International Association


From tinsmiths to high tech specialists, Sheet Metal Workers have applied their skills long before our founding members organized our union on January 25, 1888 in Toledo, Ohio. We have established a reputation as a highly skilled workforce whose abilities benefit everyone where they work, live, play and pray. We reach for new avenues in our constant pursuit for a better quality of life for all workers.
