Aluminium Angle Bars

Aluminium Angle Bars


Aluminium angle bar, also commonly referred to as aluminium angle, aluminium angle section and aluminium angle iron, is an extruded aluminium product that has corrosion resistance and is lightweight making it ideal for fabrication works. There are two types of aluminium angle bar: “Aluminium equal angle bar” and “Aluminium unequal angle bar”.

Aluminium angle bar is often used to support and protect structural buildings from corrosion and provide extra strength and stability. Aluminium angle bar is versatile and can be easily welded, cut and machined.


Uses of aluminium angle bar include construction, marine, transport, automotive, food processing, heavy machinery, industrial, manufacturing and aviation industries.


Two of the most widely used grades of aluminium angle bar alloys are 6061 and 6063. AA6061 is the most versatile of all heat-treatable aluminium angle bar alloys, while maintaining most of the good qualities of aluminium. It offers a range of good mechanical properties and superior corrosion resistance. It can be welded and fabricated by many commonly used techniques and has good workability in the annealed condition. AA6061 offers the benefit of low weight yet provide strong structural support, therefore it is suitable for heavy-duty structures such as marine components, pipelines and frames.

AA6063 has a fairly low strength, but excellent corrosion resistance, as compared to other aluminium alloys. Given its resistance to corrosion, aluminium angle bars made in 6063 aluminium are excellent for outdoor use and architectural trim. 6063 aluminium has good weldability and is easier to form than multipurpose 6061 aluminium. For aluminium angle bars that require greater strength, AA6063 can be heat treated for increased strength.

Common Sizes, Grades and Specifi­cations

AA6061Up to 150mmUp to 6000mmFrom 1.0mm
AA6063Up to 150mmUp to 6000mmFrom 1.0mm
AA6082Up to 150mmUp to 6000mmFrom 1.0mm

Other aluminium angle bar sizes and grades are available upon request. You can request to cut your aluminium angle bars down to size.


Mill FinishOriginal nature of aluminium, where no mechanical or chemical finish is done on the surface.
Brushed FinishDistinctive look with uniform pattern of fine lines parallel to the brushing direction.
PretreatmentEtched or cleaned with an alkaline or acidic material before a pretreatment coating is applied. Applied coating enhances powder or paint adhesion and provides resistance against corrosion.
Bright DippingElectro-brightening treatment to produce smooth surface with high lustre and “mirror” finish.
AnodisingProtective layer of aluminium oxide providing increased resistance to corrosion and wear.
Powder CoatingDurable film coating that can meet stringent performance criteria, offering a wide range of colours.
