Turning raw metal into functional, high-precision parts isn’t simple. From cutting and bending to welding and finishing; the metal fabrication process involves multiple techniques that work together seamlessly. The methods you choose affect everything, from part durability to production cost.

In this guide, we’ll walk you through the metal fabrication process step by step, explore key metal fabrication techniques, and share how to fabricate metal.

What Is Metal Fabrication?

Metal fabrication is the industrial process of converting raw metal materials. For example, sheet metal, rods, bars, or tubes, into finished components/assemblies. This process may include cutting, shaping, forming, joining, and finishing operations. depending on your product requirements.

The 7 Steps of Metal Fabrication Process

Many wonder what is the process of metal fabrication. The metal fabrication process follows a systematic approach that transforms raw materials into finished products. You could say that each step builds upon the previous one.

Let's look at each of the metal fabrication process.

Step 1: Designing

The first step is the designing phase. It essentially lays the foundation for the entire project. It determines not only how the final product will look and function. But also how efficiently it can be produced.

In todays’ modern manufacturing, the design phase typically starts with computer-aided design (CAD) software. These digital designs specify exact dimensions, material requirements, and assembly instructions. Ultimately, serving as the blueprint for the entire fabrication process.

It’s also at this stage that engineers will decide which material to use. Oftentimes it comes down to these factors:

• Strength-to-weight ratio
• Corrosion resistance
• Thermal properties
• Electrical conductivity
• Machinability and formability
• Cost and availability
• Environmental impact

 

Step 2: Cutting

The metal cutting and shaping phase physically transforms the raw material. This stage involves cutting metal stock into the shapes required for further processing. Now, there are many ways this can be achieved, from laser cutting to sawing and punching. Which techniques depend on material type, thickness, complexity, and precision requirements.

The cutting stage is where raw metal takes on its first form. Sheets, plates, tubes, or bars are cut into predefined shapes for further fabrication. It’s a very important step, as its accuracy will impact all downstream operations.

There are many ways metals can be cut, from laser cutting to sawing and punching. The choice of method really comes down to 1) your material type, 2) its thickness, 3) complexity and 4) your precision requirements.

Step 3: Forming and Bending

The forming and bending phase transforms flat metal pieces into three-dimensional shapes. This step requires specialised equipment to achieve precise angles, curves, and contours without compromising the material’s structural integrity.

There most common forming processes include:

• Press Brake Forming
• Roll Forming
• Tube and Pipe Bending
• Stretch Forming

Generally speaking, the choice of method depends on factors such as material properties (since metals have varying formability), bending allowance and deduction (used to calculate bend radius and prevent cracking), and overall part geometry.

Step 4: Joining and Assembly

The joining and assembly stage is where individual metal components are combined to form functional structures. This phase transforms separate parts into cohesive assemblies. It’s achieved through joining methods, with welding being the most common metal fabrication technique in this stage.

Welding essentially creates permanent bonds by melting and fusing materials together. However, the process will vary depending on which of the four common welding techniques you choose.

Step 5: Finishing Processes

After assembly, metal-fabricated products undergo finishing processes. The main purpose is to improve their appearance and protection, and add functionality. It removes manufacturing artifacts and creates an optimal surface for subsequent treatments such as coating, polishing, or painting. Once finishing is complete, the fabrication process moves to its final stage: quality control, testing, and installation.

Step 6: Installation

This final step verifies that the finished product meets all engineering specifications and functions, as intended in its real-world application. It validates the fabrication work and transitions the product from the manufacturing floor to practical use. Whether that means fitting components into a machine, erecting structural elements, or assembling consumer goods.

Step 7: Installation and Maintenance

Finally, the finished metal components are either:

• Delivered for final assembly
• Installed on-site (e.g., railings, signage, machinery)
• Integrated into a larger system (e.g., food processing equipment)

However, keep in mind that many types of fabrication processes. Especially those used for industrial machinery or heavy structures will require long-term maintenance support.
