About Us

Representing Skilled Construction Workers in the Sheet Metal Industry

Sheet Metal Workers' Local 100 provide the best trained and safest workers in the industry. We are committed to state-of-the-art training for our members. We care about quality construction because we live in the communities where we build. So from drawing board to grand opening, the members of the Washington D.C. Building and Construction Trades' Council are true partners in the growth of our community.


A History of Protecting Workers

For over 100 years, the Sheet Metal Workers' International Association has organized local unions to provide fair wages and job safety to workers, create funds to support members’ health care and pensions and train new generations of skilled construction trades workers. Workers who continue our tradition of creating and restoring the buildings that make our community and nation proud.
