What Structural Iron and Steel Workers Do

Structural iron and steel workers install iron or steel beams, girders, and columns to form buildings, bridges, and other structures. They are commonly referred to as ironworkers.

Work Environment

Ironworkers perform physically demanding and dangerous work, often working at great heights. As a result, workers must wear safety harnesses to reduce the risk of falling.

How to Become a Structural Iron and Steel Worker

Although most structural iron and steel workers learn through an apprenticeship, some learn on the job. Certifications in welding and rigging can be helpful.

Pay

The median annual wage for structural iron and steel workers was $46,140 in May 2012.

Job Outlook

Employment of ironworkers is projected to grow 22 percent from 2012 to 2022, much faster than the average for all occupations. The need to rehabilitate, maintain, and replace an increasing number of older roads and bridges is expected to drive employment growth, as will the ongoing construction of large projects, such as high-rise buildings. Job opportunities should be best in metropolitan areas, where most large construction projects take place.

What Structural Iron and Steel Workers Do

Structural iron and steel workers
Ironworkers must adjust the position of beams.

Structural iron and steel workers install iron or steel beams, girders, and columns to form buildings, bridges, and other structures. They are commonly referred to as ironworkers.

Duties

Ironworkers typically do the following:

  • Unload and stack prefabricated steel so that it can be lifted easily with slings
  • Use a crane to lift steel beams, girders, and columns into place
  • Stand on beams or girders to help position pieces that are being lifted
  • Signal crane operators for positioning of the structural steel
  • Align beams and girders into position
  • Verify vertical and horizontal alignment of the structural steel
  • Connect columns, beams, and girders with bolts or by welding them into place
  • Use metal shears, torches, and welding equipment to cut, bend, and weld the steel

Iron and steel are important parts of buildings, bridges, and other structures. Even though the primary metal involved in this work is steel, these workers often are known as ironworkers or erectors.

When building tall structures such as a skyscraper, ironworkers erect steel frames and assemble the cranes and derricks that move structural steel, reinforcing bars, buckets of concrete, lumber, and other materials and equipment around the construction site. Workers also connect steel columns, beams, and girders according to blueprints and instructions from construction supervisors. A few also may install precast walls or work with wood or composite materials.

Although most of the work involves erecting new structures, some ironworkers also may help in the demolition, decommissioning, and rehabilitation of older buildings and bridges.

As they work, ironworkers use a variety of tools. They use rope (called a tag line) to guide the steel while it is being lifted; they use spud wrenches (long wrenches with a pointed handle) to put the steel in place; and they use driftpins or the handle of the spud wrench to line up the holes in the steel with the holes in the framework. To check for alignment, they may use plumb bobs, laser equipment, or levels.

Structural steel generally arrives at the construction site ready to be installed—cut to the proper size, with holes drilled for bolts and numbered for assembly.

Some ironworkers are assemblers and fabricators. They fabricate metal in shops, which are usually located away from the construction site.

Work Environment

Structural iron and steel workers
Ironworkers often must work at great heights and risk falling.

Structural iron and steel workers held about 58,100 jobs in 2012. About 44 percent were employed in the foundation, structure, and building exterior contractors industry and about 23 percent were employed in nonresidential building construction.

Ironworkers help build the supporting structure for bridges and for industrial, commercial, and large residential buildings. In doing so, they perform physically demanding and dangerous work. For example, they usually work outside in most types of weather, and some must work at great heights. As a result, workers must wear safety devices, such as harnesses, to reduce the risk of falling.

Work Schedules

Nearly all ironworkers work full time. Those who work at great heights do not work during wet, icy, or extremely windy conditions.

Injuries and Illnesses

Ironworkers experience several work-related deaths each year due to falls. In addition to falls, workers may experience cuts from sharp metal edges and equipment, as well as muscle strains and other injuries from moving and guiding heavy structural steel.

How to Become a Structural Iron and Steel Worker

Structural iron and steel workers
Most ironworkers learn their trade through a 3- or 4-year apprenticeship.

Although most structural iron and steel workers learn through an apprenticeship, some learn on the job. Certifications in welding and rigging can be helpful.

Education

A high school diploma is generally required. Courses in math, shop, blueprint reading, and welding can be particularly useful.

Training

Most ironworkers learn their trade through a 3- or 4-year apprenticeship. For each year of the program, apprentices must have at least 144 hours of related technical training and 2,000 hours of paid on-the-job training. Nearly all apprenticeship programs teach both reinforcing and structural ironworking. On the job, apprentices learn to use the tools and equipment of the trade; handle, measure, cut, and lay rebar; and construct metal frameworks. In technical training, they are taught basic mathematics, blueprint reading and sketching, general construction techniques, safety practices, and first aid.

After completing an apprenticeship program, they are considered to be journeymen who perform tasks with less guidance.

A few groups, including unions and contractor associations, sponsor apprenticeship programs. The basic qualifications required for entering an apprenticeship program are as follows:

  • Minimum age of 18
  • High school diploma or equivalent
  • Physical ability to perform the work
  • Pass substance abuse screening

Licenses, Certifications, and Registrations

Many ironworkers become welders certified by the American Welding Society. Certifications in welding, rigging, and crane signaling may increase a worker’s usefulness on the jobsite and result in higher pay.

Important Qualities

Balance. Because workers often walk on narrow beams, a good sense of balance is important to keep them from falling while doing their job.

Depth perception. Ironworkers must be able to envision the distance between objects and themselves to work safely. Ironworkers that misjudge the distance between girders, for example, may cause the girders to collide, which can be dangerous and costly.

Physical stamina. Ironworkers must have physical endurance because they spend many hours on their feet while connecting heavy and cumbersome beams.

Physical strength. Ironworkers must be strong enough to guide heavy beams into place and tighten bolts.

Unafraid of heights. Some ironworkers must not be afraid to work at great heights. For example, as they erect skyscrapers, workers must walk on narrow beams—sometimes over 50 stories high—while connecting girders.

Employment of ironworkers is projected to grow 22 percent from 2012 to 2022, much faster than the average for all occupations.

The need to rehabilitate, maintain, or replace an increasing number of older highways and bridges is expected to drive employment growth, particularly because state and federal legislatures will likely fund these infrastructure projects.

In addition, steel is an important part of commercial and industrial buildings. Future construction of these structures should create additional demand for ironworkers.

Job Prospects

Those who are certified in welding, rigging, and crane signaling should have the best job opportunities. Those with prior military service experience are also viewed favorably during initial hiring.

Employment opportunities should be best in metropolitan areas, where most large commercial and industrial buildings are constructed.

As with many other construction workers, employment of ironworkers is sensitive to fluctuations of the economy. On the one hand, workers may experience periods of unemployment when the overall level of construction falls. On the other hand, shortages of workers may occur in some areas during peak periods of building activity.
