Iron Workers International (The International Association of Bridge, Structural, Ornamental and Reinforcing Iron Workers Union), AFL-CIO, is a proud trade association whose beginnings go back to the 1890s. We currently represent 120,000 members in North America. If there were no ironworkers, cities like New York, Chicago, Quebec and Los Angeles would look very different than they do today - no skyscrapers, no bridges, no office buildings. Transportation would be radically different too. How would the millions of commuters every day get to work without the bridges built by - you guessed it - ironworkers. Without ironworkers to erect the skeleton of a structure, no other trade would be able to install their work. That's why ironworkers are the most respected tradesperson in the construction industry. When you're an ironworker, the sky is the limit. The possibilities of training, earning, providing, advancing, building are endless. There is no limit to what ironworkers can do!
