Iron workers Union of America

International Association/Bridge & Structural Iron Workers


In the late 1880's , steel replaced wood & stone as a primary load- carrying material in the erection of bridges and buildings. Through the thoughts of caring for families, in times of sickness/injury, the voices of workers were heard. Henceforth the Iron workers Union was established February 4th 1896.

The Union currently has 120,000 members in North America. Members of the Union have worked on some of the major constructions of American History, such as the Golden Gate Bridge, the World Trade Center, the Sears Tower and many others.



Today the Union is spread throughout the United States and parts of Canada. Though Houston Pennsylvania, is where most of the focus is right now. The Union supports safety within the workforce and skillfully, to get the job done right.

They provide many benefits and support for the members. These benefits include the advantage of working under a collective bargaining agreement that brings bigger paychecks, better health and retirement benefits, more secure jobs, and safe working conditions.

They now have their own Constitution by union members and employers follow.
