What Is Sheet Metal Fabrication?
Sheet metal fabrication is a manufacturing process that transforms flat metal sheets into custom components and assemblies through cutting, forming, joining, and finishing operations. The process uses materials such as aluminum, stainless steel, steel, copper, and brass to produce parts with specific shapes, dimensions, and functional requirements.
Sheet metal fabrication typically includes processes such as laser cutting, bending, welding, stamping, machining, and surface finishing. These methods allow manufacturers to create precision metal parts ranging from simple brackets and panels to complex enclosures and structural assemblies.
