Who We Are

Ironworkers Local #512 was founded in 1937 with the merger of Minneapolis (#19, 1904) and St. Paul (#94, 1906) by the International Association of Bridge, Structural, Ornamental and Reinforcing Ironworkers. Duluth (#563) and North Dakota (#793) joined in 2004. Today, Local #512’s area spans approx. 175,000 sq miles with over 2000 active members.

Ironworkers play a vital role in nearly ALL aspects of our built environment and Infrastructure. Whether it be new construction, renovation or maintenance on commercial, industrial, transportation, power generation or public facilities projects, Ironworkers had a hand in creating it.

Beginning with placing and securing the reinforcing in foundations and bridges, then hoisting, rigging, connecting, bolting and welding the beams, columns and other components that form the structural frame of our buildings, along with installing the architectural/ornamental railings, fences and exterior facades. It’s easy to understand why and Ironworker will drive by a building, cross a bridge or look at a city skyline and say to friends and family “I BUILT THAT!”
