Fabrication sheet metal workers, sometimes called precision sheet metal workers, make ducts, gutters, and other metal products. Most work in shops and factories, operating tools and equipment. Although some of the fabrication techniques used in large-scale manufacturing are similar to those used in smaller shops, the work may be highly automated and repetitive. Many fabrication shops have automated machinery, and workers use computer-aided drafting and design (CADD) and building information modeling (BIM) systems to make products.
Installation sheet metal workers install heating, ventilation, and air conditioning (HVAC) ducts. They also install other sheet metal products, such as metal roofs, siding, or gutters. They typically work on new construction and on renovation projects.
Maintenance sheet metal workers repair and clean ventilation systems so the systems use less energy. Workers remove dust and moisture and fix leaks or breaks in the sheet metal that makes up the ductwork.
Testing and balancing sheet metal specialists ensure that HVAC systems heat and cool rooms properly by making sure that air is transferred through sheet metal ducts efficiently.
