Ironworkers and steelworkers 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, torches, hand tools, 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
- Install metal decking used in building construction.
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 also help in the demolition, decommissioning, and rehabilitation of older buildings and bridges.
Structural ironworkers and steelworkers erect, place, and join steel girders, columns, and other pieces to form structural frameworks. They also may assemble precut metal buildings and the cranes and derricks that move materials and equipment around the construction site. Some ironworkers install precast walls or work with wood or composite materials.
Reinforcing ironworkers and rebar workers position and secure steel bars or mesh in concrete forms for purposes of reinforcement. Those who work with reinforcing steel (rebar) are sometimes called rod busters, in reference to rods of rebar.
