About Us

The International Brotherhood of Boilermakers represents more than 50,000 skilled craftsmen and women and industrial workers who work in heavy industry, shipbuilding, manufacturing, railroads, cement, mining, and related industries. We construct and repair electric power plants, refineries, pulp and paper mills, and steel mills. We build naval ships and commercial tankers, repair locomotives, make cement, and mine coal, gypsum, and talc. We forge tools for industry and make consumer goods.

Our union aggressively prepares, promotes, protects and defends our members. We’re the right choice for workers who want an innovative, forward-thinking union that looks out for its members today and tomorrow. And we’re the right choice for owners, contractors and other employers who want to get the job done right —on time, within budget and safely. Every time.
