Understanding Aluminium Fabrication, Its Process and Importance.  

Aluminium fabrication is the creation of various structures by cutting, bending or using other assembling processes. Each aluminium type or alloy requires a unique machining process, and LA Metals has the expertise to provide leading fabrication services for your needs.

The different types of fabrication available are as wide and varied as the uses the metal can be put to, from extrusion, drawing, machining, forming and welding to cutting, drilling, milling and routing. Aluminium is perfect for a variety of fabrication uses as it is durable, robust, lightweight, corrosion resistant, extremely ductile and perfect for bespoke shaping.

The Popular Aluminium Fabrication Processes 

How exactly is aluminium fabrication performed and by whom? Performing this innovative process requires several tools to join the pieces of aluminium together. However, it is important that fabrication is performed by experts who understand the health and safety regulations.

There are several unique ways that this process can be performed, each of which is different from the aluminium extrusion process. The fabrication process starts with preparation.

Material Preparation: Ensuring Optimal Quality 

The surface of the aluminium must be inspected and prepared using specialist treatments. Ensuring a high-quality surface before fabrication is key to improving the outcome, especially when it comes to processes such as welding – where specific coatings such as welding primers are advisable to protect the surface of the metal as it’s worked.

Once preparation is completed, some of the most popular processes to achieve aluminium fabrication include:


Computers can be an extremely effective method of automating machine tools to create a very precise finish. A CNC system can allow for automated methods of cutting and moving aluminium fabrications on a controller, meaning a greater volume of output is possible where needed.



Aluminium sheets or bars can be cut into specific shapes and sizes. There are several tools and ways to cut the metal, such as sawing, shearing, laser cutting or waterjet cutting. CNC machines are also an extremely efficient way to get exact and bespoke forms of aluminium. These machines are operated by our expert fabricators to match the tightest of tolerances.


This method is extremely useful when the section required can’t be extruded successfully. This process involves folding and forming sheets of aluminium to create unusual shapes which can be achieved with machines such as press breaks or rollers.

Drilling and Slotting

Drilling and slotting are methods of fabrication for aluminium applications that require specific holes and entry points. These applications are ideal for industries including aerospace, construction, the motor industry and more. Drilling and slotting also allow for several applications to fit together, almost like a puzzle, to create large-scale appliances.


Aluminium can be welded using techniques that can cut, combine, join and bend the metal into the desired shape and size. Welders typically use metal inert gas (MIG) or tungsten inert gas (TIG) welding tools and perform this technique for similar results to drilling and slotting – to join multiple aluminium pieces together to create a larger product.

Countersinking and Tapping

This method is similar to drilling and slotting where the latest CNC technology is utilised to provide holes to meet exact screw sizes at an efficient frequency. Countersinking is the process of cutting a hole into the aluminium which allows space for a screw or bolt. Tapping involves cutting threads on the inside surface of a hole, which provides smooth insertion of the specific screw or bolt.

What Happens After the Fabrication Process?

The final, and often unspoken, step in the aluminium fabrication process is quality control. Each fabrication method presents opportunities for errors, so a final inspection is required for every part used.

After the aluminium has been fabricated, several other finishes can be applied to add more benefits. These finishes are provided to add extra strength and durability, in addition to providing resistance to corrosion and for a more desirable visual appeal. These finishes include:
