Sheet Metal Construction

Apprenticeship Completion

Program number: 504321


Work DescriptionSheet Metal Apprenticeship

Sheet metal workers make, install and maintain air-conditioning, heating, ventilation and pollution control duct systems, as well as roofs, siding, rain gutters, downspouts, skylights, restaurant equipment, outdoor signs, and many other products made with metal sheets. They also may work with fiberglass and plastic materials. Although some workers specialize in fabrication, installation or maintenance, most do all three jobs.

Working Conditions

Sheet metal workers who fabricate sheet metal products work in shops that are well-lit and well-ventilated. However, they stand for long periods and lift heavy materials and finished pieces. Those performing installation work do considerable bending, lifting, standing, climbing and squatting, sometimes in close quarters or in awkward positions. Although duct systems and kitchen equipment are installed indoors, the installation of siding, roof, and gutters involves much outdoor work, requiring sheet metal workers to work in various kinds of weather.


  • 5-year training program
  • 9,000 hours of on-the-job training
