What is Sheet Metal? The Basic Knowledge

Sheet metal itself is known for its versatility and comes in a variety of thicknesses. It can be made from a variety of metals such as aluminum, steel, and copper.

Sheet metal fabrication processes thin sheet metal into a variety of shapes through punching, cutting, stamping, and bending. Using 3D CAD files converted into machine code, this technology allows sheet metal to be accurately molded into the final product.

 As a result, sheet metal is essential for many industries, from household appliances to industrial machinery. This is thanks to its ability to be easily molded and its inherent strength.

Sheet Metal Processing

metal fabrication

Sheet metal fabrication encompasses a wide range of technologies and processes that are primarily used to form, cut, and assemble sheet metal into desired products and components. The versatility of sheet metal has made it a key material in manufacturing industries such as automotive, aerospace, electronics, and construction. The main processes involved in sheet metal fabrication are cutting, bending and forming, joining, and surface treatment. The processes are described in detail below:


  • Cutting. A process used to cut straight lines in flat sheet metal. Machines used include shears, which can apply high forces to cut metal.
  •  Laser cutting. The use of a high-powered laser beam to melt, burn, or vaporize metal along a specified path. Allowing complex shapes to be precisely machined.
  • Waterjet Cutting. The use of a high-pressure water jet (usually mixed with an abrasive substance) to cut through material without introducing heat. Which prevents deformation of the material.
  • Plasma Cutting. Using a plasma torch to melt electrically conductive metal and blow it away with a high-speed gas jet.

Bending and Forming

  • Press forming. A machine known as a press brake produces a bend by sandwiching a sheet of metal between a punch and a die.
  • Roll Forming. Sheet metal is passed through a series of rollers that gradually mold the metal into a desired contour or shape.
  • Stamping. A stamping press uses a die and high pressure to shape or cut metal into flat forms, or to mold metal into specific shapes, textures, or patterns.


  • Welding. The use of heat to fuse two pieces of metal, with or without additional filler material.
  • Riveting. Joining two pieces of metal together using metal pins or rivets.
  • Bonding. Bonding metal surfaces together using glue or epoxy.

Surface Preparation

  • Painting or powder coating: Used for aesthetic purposes and to protect against corrosion and abrasion.
  • Blasting or sanding: Used to clean metal surfaces or remove burrs and sharp edges.
