Aluminium Unequal Angles

Aluminium unequal angles are aluminium extrusions that have unequal sides. Being both lightweight and highly rust-resistant, aluminium angles are commonly used to build commercial vehicle bodies, horse boxes and trailers. Ease of working aligned with strength and durability make them ideal for both structural and decorative purposes.

Aluminium unequal angles have great weldability and are also suitable for polishing, anodising and powder coating, all of which allow them to be used in various decorative applications such as shop fittings, signage and exhibition stands.

What are aluminium unequal angles?

Aluminium unequal angles are made by extruding aluminium through a die that shapes it into the required profile. Being both lightweight and highly rust-resistant, aluminium angles are commonly used to build commercial vehicles and other structures that require a degree of weather resistance.

The resulting product has two sides of unequal length, with a right angle between them. The angle between the sides can vary from 90 degrees to less than 90 degrees, depending on the application.

Aluminium unequal angles are lightweight, strong, and corrosion-resistant, which makes them an ideal material for a wide range of challenging applications. They are often used in the construction of buildings, bridges, and other structures, as well as in the manufacturing of machinery, equipment, and vehicles. They can be cut, drilled, and welded to fit specific requirements, and can be finished with a variety of coatings to enhance their appearance and increase their durability.

What are aluminium unequal angles used for?

Aluminium angles are highly versatile and can be used for a range of applications. Here are some of the most common uses for high-quality aluminium angles.

Commercial Vehicle Bodies

Aluminium unequal angles are ideal for use in commercial vehicle bodies due to their high strength-to-weight ratio. They are also highly corrosion-resistant, which is important for vehicles that are constantly exposed to harsh weather and challenging road conditions. Aluminium can bear heavy loads, without adding unnecessary weight to the vehicle. They provide a robust framework, with a fraction of the weight of steel. They are often used to form the chassis and frame of the vehicle, as well as to create compartments and storage areas within the body.

Horse boxes

Horse boxes require materials that are strong, lightweight, and durable, in order to provide a secure and comfortable environment for the horses being transported.

Aluminium unequal angles are an ideal material for use in horse boxes due to their high strength-to-weight ratio and excellent corrosion resistance. They are also easy to work with, which allows for the creation of custom designs that can accommodate specific animal transportation needs. The ramp in particular needs to be robust and able to support the weight of a horse.

Marine Applications

In marine applications, aluminium unequal angles are used in the manufacturing of boats, ships, and other watercraft. They are used as structural supports, framing components, and reinforcements in the hull and deck of the vessel. They can also be used to create fixtures and fittings such as rails, ladders, and brackets.

Aluminium unequal angles are also highly corrosion-resistant due them being grade 6000. They are suitable for most outdoor application but not when saltwater is present.

What are the properties of aluminium unequal angles?


Aluminium is an excellent material for welding due to its high thermal conductivity and low melting point. These properties make it easy to weld and form strong bonds between the metal pieces. Welding aluminium allows for the creation of complex shapes and designs that would be difficult to achieve with other materials.


One of aluminium’s main properties is its corrosion resistance. Aluminium reacts with oxygen to create a protective layer of aluminium oxide. This makes aluminium an ideal material for use in environments that are highly corrosive, such as marine and industrial settings. Aluminium’s corrosion resistance makes it a good choice for outdoor applications, where it will be exposed to the elements.


Aluminium is also a very attractive material. It has a consistent silver-like finish and hides rough edges. If you need an even higher finish, aluminium unequal angles are suitable for powder coating, polishing and anodising. Powder coating involves applying a dry powder to the surface of the metal, which is then heated to create a smooth, durable finish that is resistant to chipping, scratching, and fading.
