The International Association of Bridge, Structural, Ornamental and Reinforcing Iron Workers represents skilled tradespeople who specialize in various aspects of metal construction. Members of this union, known as ironworkers, perform critical tasks in building infrastructure and structures. They erect the steel frameworks of bridges, skyscrapers, and industrial buildings, often working at great heights. Reinforcing ironworkers, also called rodmen, place and tie the steel bars (rebar) used to reinforce concrete in foundations, walls, and other structures. Ornamental ironworkers install metal stairways, catwalks, gratings, and window frames. Additionally, union members work on curtain walls, metal windows, and architectural and ornamental metalwork. Their expertise extends to welding, rigging, and operating specialized equipment essential for handling and positioning heavy steel components. The union ensures its members are trained in these specialized skills and advocates for their safety and fair compensation in this physically demanding and often hazardous field.
