The International Brotherhood of Boilermakers, Iron Ship Builders, Blacksmiths, Forgers and Helpers is a diverse union representing over 60,000 workers in the construction, shipbuilding, railroad, manufacturing, and mining industries throughout the United States and Canada.

The primary structural unit of the union is the local lodge. As our union has grown more diverse through mergers and organizing, groups of local lodges have been organized into several categories under our Constitution, to ensure the union can represent all members and deliver the appropriate services to every lodge.

In addition, many services are provided by administrative departments of the International.
