Sheet Metal Workers’ International Association
The Sheet Metal Workers’ International Association (SMWIA) serves to protect and raise the living standards of over 150,000 skilled men and women employed throughout the United States, Canada and Puerto Rico. We work in the construction, manufacturing, service, railroad and shipyard industries.
The SMWIA strives to establish and maintain desirable working conditions for its members through their employers. Doing so provides them that measure of comfort, happiness, and security to which every member is entitled to in return for his or her highly trained and skilled labor.
