Metal Fabrication

The Most Common Fabrication Techniques

Constructing metal structures requires customizing metal parts, which is called metal fabrication. Many products use metal fabrication, including automobile chassis, building panels, roofing, airplane fuselage panels, and more.

The most common metals used by industrial custom manufacturers are steel and aluminum. These two metals are prevalent due to their strength and flexibility.

Metal fabricators use several procedures, but the three most basic are cutting, shaping, and assembling. Using various tools and machines, steel and aluminum can be cut into different shapes. Once the parts are shaped, they can be assembled to form the desired structure. Assembling metals requires special techniques that vary depending on the metal.

Below are more details on each of these procedures.


Cutting is the initial step in making anything out of metal. In this step, the metal fabrication company prepares raw metal sheets for shaping.

Whatever metal needs cutting, the process requires specialized equipment. To cut metal, some metal fabricators utilize torches. In contrast, others employ computer numerical control (CNC) equipment that uses lasers, turret presses or water jets.

The product will provide the business with clean metal sheets or portions of the correct size.


Metal fabricators can also bend the raw metal once cut. There are several ways to do it.
Bending or forming the metal into the correct shape is a common technique used by some metal fabricators. It’s possible to use either a hand tool or a mechanical one.

Many industrial custom manufacturers are using press brakes to shape metal pieces. When activating this massive industrial equipment, it presses metal sheets and parts into the desired shape. It uses a punch die to force the metal into the desired shape.


Assembling is the last step in the process. This method involves putting together individual pieces of metal to form a final assembly or product. However, one may also employ other techniques. Glue, screws, and crimping seams are just a few of the many methods used by metal fabricators.

After assembly, the completed product will undergo testing and packaging for distribution.

Important Procedures in Crafting Metal

The fabrication of metal products is a critical factor in the expansion of the manufacturing industry. Despite a large arsenal of tools and processes, metal fabricators still use the Cutting, Shaping and Assembly procedure at its core. Companies in the metal fabrication industry rely on these three operations to modify raw metal into finished goods.
