Sheet Metal Workers fabricate and install ducts that are used in heating, ventilation and air conditioning. They also fabricate and install a wide variety of other products made from light or thin galvanized metals such as siding, metal decks, paint ovens, and spray booths, gutters, flashing, and dust collecting systems. The trade also includes products made from heavy or thick metals which are welded (stainless steel, aluminum, black iron) column guards, conveyors, blow pipe systems, spouts, and many more items. Sheet metal workers work in residential, industrial, and commercial settings.
Most items are fabricated in the shop, then taken to the job site to be installed. Heating and air conditioning components are purchased, then fitted together with the air duct fabricated by members.
