Find a beam's place on paper
Study the drawing or plan to learn a steel piece's size and where it belongs in the frame.
Career profile
Structural Iron and Steel Worker
Ironworkers assemble steel frameworks that hold up structures like bridges and large buildings.
Like assembling things? Here you help lift heavy steel beams, join them into a frame, and watch a structure grow around you.
A day in the life
Guide the crane's lift
Look over the hooks and cables, then signal the crane operator as the steel moves toward its spot.
Pin the holes, then bolt
Use drift pins to bring the bolt holes into line, then bolt the steel pieces into a joint.
Confirm the frame stands straight
Test the frame with a laser or a level, and any steel out of line has to move.

Quick orientation
Preparation, pay & outlook
Preparation
Usually an apprenticeshipTypical preparation combines a high school diploma or equivalent with learning the trade on the job.
Pay
$62,780 a yearNational median for structural iron and steel workers; $30.18 an hour.

Fit, tradeoffs & changing tools
You might like this if…
- You enjoy matching a drawing to physical parts.
- You keep checking small details during demanding work.
- You can coordinate your movements with other people.
Things to weigh
- Heavy work and heights bring strain and serious fall risks; protective equipment is essential.
- Jobs may require travel. Wet, icy, or very windy conditions can stop work at height.
Where AI may help
Researchers are testing digital instructions overlaid on real steel parts, called augmented reality, to assist fabrication before pieces reach the site.
What people still lead
On site, workers still judge alignment and coordinate moving steel with the crane operator.
What we can’t predict yet
How far digital guidance will extend from fabrication into changing field conditions—and how much positioning it could automate—remains uncertain.
Pay in context
Earnings
Apprentice pay can rise as your skills develop.
The national range
The median was $62,780 annually, or $30.18 hourly. The lowest 10% earned under $44,580; the highest 10% earned over $108,260. These are wage ranges, not career stages.
Workplace pay differs
Annual medians were $73,470 in heavy and civil engineering construction, $63,340 with foundation, structure, and building exterior contractors, and $61,930 in nonresidential building construction.
Openings beyond new jobs
The projected 5,900 annual openings include replacement needs. They are a national forecast, not a count of jobs available near you today.
Getting started
Enter an apprenticeship
Usually 3–4 years.Paid
- What the route involves
- Work alongside experienced ironworkers and attend classes and hands-on training.
- What it can lead to
- Completing the program earns journey-level recognition.
- What to check
- A diploma or equivalent is generally required; check the sponsor's admission rules.
Learn through an employer
- What the route involves
- Train on the job to use tools and construct frameworks.
- What it can lead to
- Build working skills through employer-provided training.
- What to check
- Training length varies; some employers do not require a diploma.
Two routes combine employment with learning the trade.
After entry
Career paths
This starts where the entry routes leave off: early work, growing capability, and advancement or specialization.
Get established
Build reliable habits with tools, drawings, and the crew while learning to assemble framing.
Develop precision
Become more capable at aligning members and completing connections.
Lead a crew
Experience can lead to supervising other ironworkers.
Where you can work
New building sites
You assemble delivered steel into commercial or industrial building frames. Your work depends on the lifting sequence and coordination with the crane crew and other trades.
- Outdoors
- Field work
- Physical demands
- Safety-sensitive
Bridges and facilities being repaired
Some crews replace steel while a structure remains in service. Restricted access, live rail lines, or operating equipment can shape when and how the crew reaches a connection.
- Field work
- Physical demands
- Safety-sensitive
Try it
See whether the job clicks before you commit to the path.
Sketch a small frame with numbered columns and beams, then recreate it on a table using cardboard strips and tape. Check each connection against your drawing. Notice whether you enjoy translating a plan into aligned parts.
Stay safe: Keep it tabletop-sized; this explores assembly, not readiness for heights or steel erection.
