We are more than 200-members strong who are well-trained and ready to work with and for our signatory contractors.
We are a Local Union chapter of the International Association of Bridge, Structural, Ornamental and Reinforcing Ironworkers.
You’ll find our work at the heart of a building’s structure. Our members erect the structural framework of buildings and also reinforce its foundation. We also are essential in a variety of projects in both the commercial and industrial projects such as erection of bridges, power plants, steel mills, oil refineries and blast furnaces.
