Ironworkers raise the steel frames of buildings and bridges, place the rebar that reinforces concrete, and install metal stairs, railings and decking. California pays them about $13,600 above the national median, and in San Jose the median tops $109,000. Most California ironworkers come up through a union apprenticeship.

What makes a good ironworker apprentice

From the dean’s desk

Being a good welder, showing up on time, and not being afraid of heights.

  • Welding: ironworkers weld and cut steel on the job, so strong welding skills make you more useful from day one. A welding class or certification before you apply helps.
  • Reliability: crews depend on every member being there on time. Being dependable is how apprentices keep getting dispatched.
  • Comfort at heights: structural ironworkers walk beams and work on open steel high above the ground, tied off with fall protection.

How the apprenticeship works

California’s field ironworker apprenticeship standards call for at least four years and 5,600 hours of on-the-job training, plus at least 160 hours of classes a year. Training covers fabrication (layout, welding, burning, bolting), installation of structural and reinforcing steel and decking, and rigging and safety.

Apprenticeships are run with ironworker union locals around the state. In Southern California, for example, Cerritos College partners with Local 433 (structural) and Local 416 (reinforcing) so apprentices can earn college credit and even an associate degree while they train. Basic requirements usually include being 18, a high school diploma or GED, and the physical ability to do the work.
