Career Overview

If you have good technical, math and mechanical skills, as well as good dexterity and physical strength, you may enjoy a career as an assembler and fabricator. Metal assemblers are responsible for creating and assembling metal parts at a manufacturing plant while structural iron and steel workers, sometimes called iron workers, are responsible for assembling those parts at a construction site.

Metal assemblers and fabricators create metal pieces and fit them together. Their job tasks include interpreting blueprints, adjusting parts so that they will fit together and assembling parts using hand tools, nuts, bolts and screws. If they work with metal parts used to create buildings, they may be called structural metal fabricators and fitters. Structural iron and steel workers assemble and connect metal pieces at the construction site. Their job duties may include unloading, lifting and aligning prefabricated beams; measuring the alignment of those beams; and connecting beams together. These individuals work outside to create the basic building structure. Individuals with good balance and who are not afraid of heights might be a good fit for employment as a structural iron and steel worker.
