What is the process of fitting metal sheets into various shapes called?

The process of fitting metal sheets into various shapes is most accurately attributed to duct fabrication. This process involves cutting, bending, and assembling metal sheets to create the specific forms required for HVAC systems, such as ductwork. Duct fabrication is essential in ensuring that air flows efficiently through a building’s ventilation system, allowing for effective climate control.

While sheet metal rolling refers to reducing the thickness of the metal or bending it into curves, particularly in industrial applications, and metal stamping involves shaping metal through a die, these processes do not specifically encompass the comprehensive method of assembling and forming metal sheets into various configurations required for HVAC installation. Welding, on the other hand, is a joining process that involves fusing metal parts, rather than shaping sheets into specific forms.
