What is a Sheet Metal Worker?

Sheet metal workers are skilled craftspeople who fabricate, assemble, install, and repair products made from thin metal sheets. They read engineering and architectural drawings, develop patterns using CAD software, operate metalworking equipment, and install sheet metal products according to specifications and building codes. The work encompasses a wide range of applications, from HVAC systems and metal roofing to kitchen equipment and decorative architectural features.

What makes this trade unique is that sheet metal workers don’t just install products—they design and create them from raw materials. This combination of creativity, technical skill, and hands-on craftsmanship sets the profession apart from other construction trades.
