Aluminium Flat Bars

Aluminium Flat Bars


Aluminium flat bar, also referred to as aluminium rectangular bar, is an extruded aluminium product that has corrosion resistance and is lightweight making it easy to work with in a wide variety of applications. Aluminium flat bar offers an excellent combination of weldability, machinability, stability and excellent strength, which is why it is used in many different industries.


Uses of aluminium flat bar include construction, marine equipment, mining, automotive, food processing, engineering, industrial, manufacturing and aerospace industries.


Two of the most widely used grades of aluminium flat bar alloys are 6061 and 6063. AA6061 is the most versatile of all heat-treatable aluminium flat 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 has a good strength-to-weight ratio, therefore it is suitable for heavy-duty structures such as marine components, medical assemblies and aircraft construction.

AA6063 has a fairly low strength, but offers high quality surface and excellent corrosion resistance, as compared to other aluminium alloys. Given its resistance to corrosion, aluminium flat bars made in 6063 aluminium are excellent for outdoor use and architectural trim. 6063 aluminium flat bar is widely used within commercial and architectural industries due to its high resistance to corrosion and exceptional finishing characteristics. 6063 aluminium has good weldability and is easier to form than multipurpose 6061 aluminium. For aluminium flat bars that require greater strength, AA6063 can be heat treated for added strength.

Common Sizes, Grades and Specifications

AA6061Up to 200mmUp to 6000mmFrom 2.0mm
AA6063Up to 200mmUp to 6000mmFrom 2.0mm
AA6082Up to 200mmUp to 6000mmFrom 2.0mm

Other aluminium flat bar grades and sizes are available upon request. You can request to cut your aluminium flat 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.
