Reinforcing Iron and Rebar Workers

It takes nerves of steel and muscles of iron, to work hundreds of feet above the ground, building structures that push up to merge with the clouds. Ironworkers have what it takes to help build the supporting structures for bridges, large buildings, and roads. Consulting sketches and blueprints to guide their work, ironworkers move prefabricated iron and steel by hand and signal crane operators to lift and position it. Using a variety of tools, they cut and shape the iron and steel, then weld or bolt it into place. Getting these heavy materials into the right, level position is key to structural integrity, and requires specialized tools to ensure it. It takes good balance and coordination, strength and stamina to make it in any specialty in this field. Structural iron and steel workers connect steel columns and girders for tall structures. Although wet, icy, or windy conditions can stop work, work is outdoors in most types of weather. With the risk of falls, cuts, and muscle strain, precautions must be taken. Reinforcing iron and rebar workers use steel and iron to strengthen concrete for highways, buildings, and bridges. They must be able to carry, bend, cut, and connect rebar quickly to help keep projects on schedule. Most ironworkers work full time in the construction industry, and learn their trade through a 3-4 year apprenticeship. A high school diploma or equivalent is generally required.

Ironworkers install structural and reinforcing iron and steel to form and support buildings, bridges, and roads.

What Do Reinforcing Iron and Rebar Workers Do?


Ironworkers typically do the following:

  • Read and follow blueprints, sketches, and other instructions
  • Unload and stack prefabricated iron and steel so that it can be lifted with slings
  • Signal crane operators who lift and position structural and reinforcing iron and steel
  • Use shears, rod-bending machines, and welding equipment to cut, bend, and weld the structural and reinforcing iron and steel
  • Align structural and reinforcing iron and steel vertically and horizontally, using tag lines, plumb bobs, lasers, and levels
  • Connect iron and steel with bolts, wire, or welds

Structural and reinforcing iron and steel are important components of buildings, bridges, roads, and other structures. Even though the primary metal involved in this work is steel, workers often are known as ironworkers or erectors. Most of the work involves erecting new structures, but some ironworkers may also help in the demolition, decommissioning, and rehabilitation of older buildings and bridges.

When building tall structures such as skyscrapers, structural iron and steel workers erect steel frames and assemble the cranes and derricks that move materials and equipment around the construction site. Workers connect precut steel columns, beams, and girders, using tools like shears, torches, welding equipment, and hand tools. A few ironworkers install precast walls or work with wood or composite materials.

Reinforcing iron and rebar workers use one of three different materials to support concrete:

  • Reinforcing steel (rebar) is used to strengthen the concrete that forms highways, buildings, bridges, and other structures. These workers are sometimes called rod busters, in reference to rods of rebar.
  • Cables are used to reinforce concrete by pre- or post-tensioning. These techniques allow designers to create larger open areas in a building because supports can be placed farther apart. As a result, pre- and post-tensioning are commonly used to construct arenas, concrete bridges, and parking garages.
  • Welded wire reinforcing (WWR) is also used to strengthen concrete. This reinforcing is made up of narrow-diameter rods or wire welded into a grid.

Structural metal fabricators and fitters manufacture metal products in shops, usually located away from construction sites.

Job Details

Reinforcing Iron and Rebar Workers typically do the following:

  • Determine quantities, sizes, shapes, and locations of reinforcing rods from blueprints, sketches, or oral instructions.
  • Space and fasten together rods in forms according to blueprints, using wire and pliers.
  • Position and secure steel bars, rods, cables, or mesh in concrete forms, using fasteners, rod-bending machines, blowtorches, or hand tools.
  • Cut rods to required lengths, using metal shears, hacksaws, bar cutters, or acetylene torches.
  • Place blocks under rebar to hold the bars off the deck when reinforcing floors.
  • Cut and fit wire mesh or fabric, using hooked rods, and position fabric or mesh in concrete to reinforce concrete.
  • Bend steel rods with hand tools or rod bending machines and weld them with arc-welding equipment.

Education and Experience

A high school diploma or equivalent is typically required to enter the occupation.  Most workers in this sub-sector learn through an apprenticeship and on-the-job training.  Structural iron and steel worker occupations usually need three to four years of training involving both on-the-job experience and informal training with experienced workers.  Several groups, such as unions and contractor associations, sponsor apprenticeship programs.

Career Outlook

  • Annual pay: As of May 2019, Reinforcing Iron and Rebar Workers earned approximately $49,000
  • Employment growth forecast 2018-2028: 11%
  • Entry-level education: High school diploma or equivalent is generally required to enter an apprenticeship for this career sub-sector job.

 Career Growth Opportunity

Certifications in welding, rigging, and crane signaling may make Reinforcing Iron and Rebar Workers more attractive to prospective employers.  Future construction of commercial and industrial structures is expected to require these workers. The need to rehabilitate, maintain, or replace an increasing number of older highways and bridges is also expected to lead to some employment growth.  After gaining experience, Reinforcing Iron and Rebar Workers may advance to become a supervisor or a manager, a position in which they have more responsibilities and are tasked with directing other workers.
