A sheet metal worker/fabricator is a tradesperson who fabricates or installs products made from thin metal sheets.
A sheet metal fabricator is a skilled tradesperson who specializes in creating and installing components from sheet metal, often working in production environments, while a sheet metal worker is primarily involved in the installation, assembly, and maintenance of sheet metal components, such as ducts, roofing, siding, and HVAC systems.
Thousands of years ago, Ancient Egyptians made jewelry from materials similar to sheet metal. Metals suited for rolling into sheets included copper, iron, zinc, and, later, steel. Tin was often used to coat iron and steel sheets to protect them from rust. This tin-coated sheet metal was known as tinplate
Initially, sheet metal was produced manually, but water-powered rolling mills replaced this process in the late 17th century. Sheet metal appeared in the United States in the 1870s, where it was used for shingle roofing, stamped ornamental ceilings, and exterior facades. Sheet metal was a common building product until World War II, when metals of all sorts were needed for the war effort, and the industry struggled. However, some U.S. companies, such as the W.F. Norman Corporation, were able to remain in business by making other products.
Later, historic preservation projects facilitated the revival of ornamental sheet metal. Today, there are more than 7,000 sheet metal contractors and fabrication shops in the United States alone. Materials used in sheet metal today include stainless steel, aluminum, and brass, among others.
Sheet metal is used in various industries for its strength, versatility, and ability to be shaped. The craft is commonly used for car bodies, chassis, and other components, as well as in aircraft fuselages and wings. In building construction, it is used in roofing, cladding, and structural components. In HVAC systems, it is used in ducting, bracketry, and electrical panels. It is also found in appliances such as microwave ovens and washing machines, in their outer casings and internal brackets.
Sheet metal workers fabricate or install products that are made from thin metal sheets. Sheet metal workers are often required to lift heavy materials and stand for long periods, while those who install sheet metal must bend, climb, and squat.
Generally, sheet metal workers need a high school diploma or the equivalent. Individuals interested in becoming sheet metal workers should take high school classes in algebra and geometry. Vocational or technical school courses in blueprint reading, mechanical drawing, welding, and metalworking are also helpful. These programs provide the basic welding and sheet-metal fabrication knowledge necessary on the job. Some manufacturers maintain partnerships with local technical schools to develop training programs specific to their factories.
Most construction sheet metal workers learn their trade through 4-5-year apprenticeships, which include both paid on-the-job training and related technical instruction. Apprentices learn construction basics like blueprint reading, math, building code requirements, and safety practices. Welding may also be included in the training. Some workers start out as helpers before entering apprenticeships.
Apprentice programs are often sponsored by unions or businesses.
Upon completion of an apprenticeship, sheet metal workers are journey workers who are qualified to perform tasks on their own.
Requirements will differ from one jurisdiction to another, but sheet metal workers are required to be licensed in some jurisdictions. Sheet metal workers may also earn certifications for several of the tasks that they perform, and even when this is not required, these certifications can lend credibility and boost resumes. The Fabricators & Manufacturers Association (FMA) offers a certification in precision sheet metal work.
The union representing sheet metal workers is the International Association of Sheet Metal, Air, Rail and Transportation Workers (SMART), which was formed through the 2014 merger of the Sheet Metal Workers' International Association and the United Transportation Union.
