What Is Sheet Metal Fabrication?

Sheet metal fabrication is a manufacturing process used to create precise metal parts by cutting, bending, and forming flat metal sheets into finished components. This process delivers strong, lightweight, and repeatable parts suitable for both prototypes and production applications.

How Sheet Metal Fabrication Works

Flat metal sheets are first cut using processes such as laser cutting or punching, then formed using press brakes or forming tools. Additional operations like welding and hardware insertion are applied to achieve the final shape and functionality.

Fabrication Workflow

The process begins with a CAD design, followed by material selection, cutting, forming, and assembly. Each step is controlled to ensure dimensional accuracy, consistent quality, and efficient production.

Sheet Metal Forming Capabilities

Different forming techniques are used depending on part geometry and material thickness, allowing simple brackets to complex enclosures to be produced with reliable precision and structural integrity.

Sheet Metal Fabrication Processes We Offer

We provide a complete range of sheet metal fabrication processes to support both simple and complex parts, from prototypes to full-scale production.

Sheet Metal Tolerances & Sizes

Sheet metal fabrication tolerances depend on material type, sheet thickness, and the selected cutting and forming processes. Proper design allowances help maintain dimensional accuracy across both prototype and production parts.
