Sheet metal work involves the use of thin sheets of metal, such as steel, aluminum, or other alloyed metals, to create a variety of products used in both manufacturing and construction. Sheet metal workers may specialize in on-site installation or shop manufacturing of sheet metal products, or in servicing and maintenance of installed equipment and systems. Some of the duties and responsibilities of sheet metal workers include:

• Building and installing products such as eaves-troughs, air and heat ducts, roof decking, and sheet metal buildings.
• Laying out, measuring, and marking sheet metal.
• Working with computerized equipment to cut, bend, or straighten sheet metal.
• Welding sheet metal parts.
• Polishing seams, joints, and rough surfaces.
• Reading and interpreting sketches and work specifications.

Sheet metal workers may work indoors or outdoors, on construction sites or in a shop. They may work independently or collaborate with other construction professionals. The job can be physically demanding, and sheet metal workers may work at considerable heights and have to lift heavy materials and equipment. Safety is a top priority, and sheet metal workers are trained to work safely and wear special equipment to protect against injury. To become certified as a sheet metal worker, one must complete an apprenticeship program that includes classroom hours and on-the-job training.
