A Strong History in Arizona

Our 100th anniversary

From its humble beginnings in 1910 to its 1,000-strong membership today, Local 75 can look back on many milestones, changes and improvements. One thing has remained constant: its commitment to supporting and advocating for its working families, as well as standing together as a skilled group of tradespeople who take pride in their work.

On July 6, 2010, apprentices, journeymen, retirees and leaders from through the country came together for a historic reception and dinner to commemorate the local’s centennial in Arizona.

Our local

The International Association of Bridge, Structural, Ornamental and Reinforcing Ironworkers Local 75 was chartered in July of 1910 in Miami, Ariz. In September of 1920, Ironworkers Local 75 moved its headquarters to Phoenix. Today, more than 1,000 active members and retirees participate in Local 75 membership through offices in Phoenix, Tucson and Window Rock.

Our apprenticeship program

The Standards for the Arizona Ironworkers Apprenticeship Program were approved on Aug. 27, 1946. The Arizona Steel Field Erectors Association and Ironworkers Local 75 formed a trust fund on Aug. 6, 1962. The trust fund document was called “Arizona Contractors Apprenticeship Training Fund for Ironworkers.” On Feb. 2, 1976 the trustees changed the name of the program to “Arizona Ironworkers Joint Apprenticeship and Training.” The Arizona Ironworkers Joint Apprenticeship and Training Program merged with California Field Ironworkers Joint Apprenticeship and Training on Jan. 1, 1990.

Advances in technology have allowed Local 75 to enhance the working conditions, safety and training of its members. Local 75 continues to strive to turn out the best of the best through its apprenticeship program and its ongoing training and upgrade opportunities for journeymen at its training centers in Phoenix and Tucson. Local 75 relocated and expanded its Phoenix training center in 2010.
