Sheet metal workers design, fabricate, assemble, install, and repair the sheet metal products required in a wide variety of industries and settings.

Sheet metal workers use many types of metal including black and galvanized steel, copper, brass, nickel, stainless steel and aluminum to make products such as:

  • pollution control systems, dust collecting and control systems, air-slide, grain spouting, material blowing, air-veyor and other air systems,
  • heating, ventilating and air conditioning systems,
  • solar heating and cooling systems and all integral equipment,
  • metal showcases, display neon and metal sign equipment,
  • metal cabinets, custom built tables, counters and fixtures for hospitals, kitchen equipment and items for the food service and beverage industry,
  • electrical panels and related equipment,
  • dairy, brewery and laboratory equipment,
  • metal shelving, lockers, window frames, metal doors and frames, toilet partitions,
  • flashing, coping, troughing and roof drainage systems, and
  • custom or small run fabrication of a variety of sheet metal items.

On occasion, sheet metal workers substitute fibreglass or plastic for metals.

In general, sheet metal workers:

  • lay out, measure and mark dimensions and reference lines on sheet metal according to drawings or templates,
  • use laser or plasma cutting equipment, numerically-controlled or computerized equipment, hand and power shears and snips and light metal-working equipment to cut, drill or punch, bend and shape sheet metal,
  • fasten with bolts, screws, cement, rivets, adhesives, solder or by welding,
  • install and repair sheet metal products and ensure installations conform to specifications and building codes,
  • do metal cladding of insulated piping and equipment on industrial sites,
  • manufacture and install flashing, coping for roofing applications, and
  • supply, install, service and repair air handling equipment, furnaces, fans, air terminal devices and split system air conditioners.

For more information regarding tasks and activities, please review the Trade Regulation.


Working Conditions

Sheet metal workers work from verbal instructions or blueprints, or design small jobs themselves. They make some products in a shop and install them at construction sites, but other products such as roofing and siding have to be measured and cut at the construction site. A 40-hour week is normal, but overtime may be required to meet construction deadlines. Sheet metal workers work indoors and outdoors in all types of weather. Considerable bending, reaching, working at heights or in cramped spaces may be required.


Skills and Abilities

The work is most rewarding for people who enjoy developing special skills and putting them to use in a variety of ways.

To be successful, sheet metal workers must have:

  • good physical condition,
  • a mechanical aptitude,
  • strength, stamina and the use of proper lifting techniques required to handle heavy tools and parts weighing up to 25 kilograms,
  • eye-hand coordination, spatial and form perception, good eyesight and manual dexterity,
  • the ability to visualize a finished product from a document,
  • a good background in practical mathematics, geometry and document reading,
  • the ability to stand for long periods, do some moderately heavy lifting and carrying, and work in high, awkward and noisy places,
  • patience, dependability and accuracy,
  • the ability to work in a construction or shop environment, and
  • good communication skills.


Employment and Advancement

Most sheet metal workers are employed by sheet metal, air-conditioning and heating contractors involved in residential, commercial and industrial construction. A few are self-employed or work in shops with related trades. Some are employed by roofing contractors to install flashing and coping. Since most sheet metal workers employed in Alberta work in the construction industry, employment prospects change with changing economic conditions.

Journeyperson wage rates vary, but generally range from $25 to $40 an hour, plus benefits.

Experienced sheet metal workers may become specialists in design and layout work or in estimating the cost of installations. They may advance to supervisory positions or go into business for themselves.


Working in Alberta

To work as a sheet metal worker in Alberta, a person must be a registered apprentice, an Alberta-certified journeyperson, or hold a valid recognized credential.

Individuals possessing a valid recognized credential in Alberta are eligible to receive a Blue Seal business credential after completing the necessary requirements.


Apprenticeship Training

The term of apprenticeship for a sheet metal worker is 4 years (four 12-month periods) including a minimum of 1500 hours of on-the-job training and 10 weeks of technical training each year.

Note: The sheet metal worker trade became a dual certification trade in September with the addition of gasfitter - Class B content and exams. Refer to Sheet Metal Worker FYI (May 2017).

An applicant who is not certified in Alberta as a gasfitter - Class A or Class B, will complete an apprenticeship program that includes both the sheet metal worker and gasfitter - Class B trades.

  • An applicant who previously completed courses of study or work experience related to the sheet metal worker trade or holds a related journeyperson certificate and has the employer's recommendation, may qualify for credit that could reduce the term of apprenticeship.  Inquiries about credit for previously completed courses of study or work experience can be directed to an apprenticeship representative toll-free at 1-800-248-4823.
  • A person who has previous training or work experience in the trade and wants to determine their level of skill and knowledge for entry or advanced standing in an apprenticeship program may complete the online Prior Learning Assessment Application.  
  • A high school student can become an apprentice and gain credits toward apprenticeship training and a high school diploma at the same time under the Registered Apprenticeship Program (RAP).

To learn the skills required of a sheet metal worker in Alberta and be issued an Alberta Journeyman Certificate, a person must:

Most employers prefer to hire high school graduates and may select apprentices from among their current employees.

For holders of an existing trade certificate, it can serve as an entrance requirement equivalency when registering in an additional trade.

An applicant who is certified in Alberta as a gasfitter - Class A or class B will apply to apprentice in the sheet metal worker trade. An applicant not certified as a gasfitter will apply to apprentice as a sheet metal worker and gasfitter - Class B. 

  • pay the non-refundable application fee as part of the application process 
  • complete the required on-the-job training
    - during on-the-job training, apprentice sheet metal workers earn at least 50 percent of the journeyperson wage rate in their place of employment in the first year, 65 percent in the second, 75 percent in the third, and 85 percent in the fourth year.
  • complete all of the program requirements as identified in the course outline
  • enroll in technical training
  • successfully complete all required exams
  • Technical Training Resource List
    • Each period of technical training requires apprentices to purchase specific resources and supplies.
    • Contact the training provider where you will be attending training for a complete list.

Apprentices who successfully complete the sheet metal worker and the gasfitter-Class B program will be issued two Alberta Journeyman Certificates - sheet metal worker and gasfitter-Class B.

Apprentices may attempt the Interprovincial Exam in the final period of their apprenticeship training for both sheet metal worker and gasfitter-Class B, and if successful, be granted a Red Seal.

When apprentices attend technical training, they are required to pay the applicable tuition fee and purchase course supplies.

Student loans, grants, scholarships and other financial assistance may be available. For more information see Financial Assistance, visit an Apprenticeship and Industry Training office or call toll-free to 1-800-248-4823.
