Upgrade your build with precision-cut 6063 Aluminium Box & Rectangle Sections — lightweight, strong, and corrosion-resistant. Available in 5m lengths or custom-cut to suit your project, they're the smart choice for professional results.
6063 T6 aluminium box section and rectangular section in 5m lengths, covering square (SHS) and rectangular (RHS) profiles. Lightweight, corrosion-resistant and easy to machine, with a clean mill finish suited to architectural and fabrication work.
Used for lightweight frames, shopfitting, display structures, greenhouse frames, curtain walling, signage, furniture, marine fabrication, vehicle bodywork and any application where weight and corrosion resistance matter more than maximum strength.
Material and Grade
6063 is an architectural aluminium alloy with excellent corrosion resistance and a smooth extruded finish. T6 temper means it has been solution heat-treated and artificially aged for the highest strength in the alloy. The natural mill finish can be left as-is, anodised or powder coated.
Available Sizes
Square and rectangular profiles in various wall thicknesses, all in 5m lengths. Select the size from the variant options on this page.
Weight Advantage
Aluminium weighs roughly one-third of steel for the same section dimensions. A 5m length of aluminium box section is significantly lighter than the equivalent steel, making it easier to handle, transport and install — particularly on overhead or elevated work.
Fabrication
6063 T6 cuts cleanly with a fine-tooth chop saw or mitre saw. It welds with TIG or MIG using aluminium filler rod and argon gas. It can be drilled, tapped and machined with standard tooling.
Frequently Asked Questions
What sizes of aluminium box section are available in 5m?
Square (SHS) and rectangular (RHS) profiles in 6063 T6. Check the product page for the full list of sizes and wall thicknesses.
What is 6063 T6 aluminium?
6063 is an architectural alloy with excellent corrosion resistance and a clean mill finish. T6 temper means solution heat-treated and artificially aged for maximum strength.
Can aluminium box section replace steel?
For weight-sensitive or corrosion-exposed applications, yes. Aluminium is one-third the weight and naturally corrosion-resistant. For maximum load-bearing at minimum cost, steel is stronger per unit size.
What is aluminium box section used for?
Lightweight frames, shopfitting, display structures, greenhouse frames, marine fabrication, curtain walling, furniture, signage and any application where weight and corrosion matter.
Can aluminium box section be welded?
Yes, with TIG or MIG welding using aluminium filler rod and argon gas. 6063 T6 welds well but the heat-affected zone loses some temper strength.
