How Does Sheet Metal Fabrication Work?

During the sheet metal fabrication process, thin sheet metal stock is placed on a flat bed where a laser cutter (1) draws programmed part patterns. Depending on the part geometry, a sheet metal punch (2) can form additional features. Once the parts are deburred, they move to the press brake (3) where they are formed into the final geometries. Additional secondary operations are often used to finish the sheet metal parts.


Our Sheet Metal Fabrication Process​

Unlike traditional sheet metal shops, we have infinite capacity and an easy-to-use online quoting system ensuring on-time shipment every time—whether you need a single part or 500 parts. You also have access to our team of knowledgeable engineers to optimize part designs and user-friendly online resources. Trim your production time and launch products faster with one local sheet metal supplier from prototypes to assemblies to finishing options.

Advantages of Sheet Metal Fabrication

The sheet metal fabrication process is ideal for metal components and can support both prototyping and production quantities.

  • Low material waste
  • Can cost-effectively scale to production volumes
  • Multiple finishing options like anodizing and powder coating

Sheet Metal Applications

Sheet metal is a versatile manufacturing process for a range of metal components. The process can support high-volume commodity products and low-volume, one-of-a-kind applications. Common sheet metal parts include:

  • Electrical enclosure
  • Parts for computer electronics
  • Chassis
  • Brackets
  • Cabinets
  • Mounts
  • Appliances

Our Sheet Metal Material Options

  • Aluminum (1)
  • Brass (2)
  • Copper (3)
  • Stainless Steel (4)
  • Steel: CR Non-treated (5)
  • Steel: CR Galvanneal and CR Galvanized (6)
