Frequently Asked Questions About Sheet Metal Fabrication

As a large company handling dozens of projects at any given time, our team at ADJ Sheet Metal often receives questions about our sheet metal fabrication services and what the process involves. Here are answers to some of the most common questions we receive:

What is sheet metal fabrication?

Sheet metal fabrication is the process of creating a finished product from raw sheets of steel, aluminum, copper, or other metals. This involves cutting, forming, and joining sheet metal together to create a finished product that is tough and durable, but lighter than a solid metal structure.

What is the sheet metal fabrication process?

The three basic processes involved in sheet metal fabrication are forming, cutting, and joining. Forming uses specialized machines to shape the metal according to the project’s needs, using techniques like stamping, rolling, bending, or stretching. The cutting process uses shears, blades, machining tools, lasers, water jets, or CNC tables to cut the metal to a desired shape and size. The joining process uses techniques like welding, brazing, spot welding, or riveting to join sheet metal pieces together or to an underlying structure. At ADJ Sheet Metal, we have two fully equipped fabrication shops to handle any project, large or small.

What are the types of fabrication?

Some of the most common fabrication methods are stamping, punching, folding, cutting, and welding. Stamping uses a set of dies under high pressure to form sheet metal into three-dimensional shapes. Punching uses a punch and die to create holes of a particular size and shape in sheet metal. Folding uses a press brake to crease or fold sheet metal. Cutting uses shears, blades, lasers, water, or a CNC plasma table to cut the metal to a particular size and shape. Welding uses high voltages to join two pieces of metal together by melting a filler material that bonds to both surfaces. Other fabrication methods include machining, rolling, and stretching,
