Career
Sheet Metal Worker
Field & Trades
Fabricates and installs the ductwork, flashing, and metal roofing systems that move air through a building and keep water out of it.
What is a Sheet Metal Worker?
A Sheet Metal Worker fabricates and installs sheet metal components on a project, most commonly HVAC ductwork, but also roofing panels, flashing, and architectural metal. A lot of the fabrication happens in a shop ahead of time, cutting and forming metal to exact duct-run dimensions from drawings, before the finished pieces move to the jobsite for installation and connection to air handling equipment. The trade has its own apprenticeship and union (SMART) distinct from an HVAC Technician, who installs and services the equipment those ducts connect to rather than fabricating the ductwork itself.
What they do
- Fabricate ductwork and sheet metal components in a shop from drawing dimensions
- Install ductwork runs on the jobsite and connect them to air handling equipment
- Install metal roofing panels, flashing, and architectural sheet metal
- Seal and insulate ductwork joints to prevent air leakage
- Read HVAC drawings and shop drawings to plan duct runs and fabrication sequencing
- Coordinate with HVAC technicians and other trades on routing through ceilings and walls
A typical day
- 6:00 AMReview the day's duct fabrication list and set up the shop's cutting and forming equipment
- 7:00 AMFabricate a run of rectangular ductwork to the dimensions on the shop drawing
- 10:00 AMMove to the jobsite to install a completed duct run above a finished ceiling grid
- 1:00 PMSeal ductwork joints and connections to meet the project's air-leakage requirements
- 3:30 PMCoordinate with the HVAC technician on final connections between ductwork and a rooftop unit

Software
Generally none; this is a hands-on field trade
Education
- Required:
- High school diploma or equivalent, then a registered apprenticeship through the SMART union, typically around four years combining paid on-the-job training with roughly 160 hours of classroom instruction per year; sheet metal work isn't separately state-licensed in most places
- Helpful:
- OSHA 10 or 30 certification (not a nationwide legal requirement, though several states, including New York, Massachusetts, Connecticut, Nevada, Missouri, and Rhode Island, legally require it for workers on public construction projects)
- Not necessary:
- A four-year college degree; the apprenticeship-to-journeyman route is the standard path into the trade
