Aluminium Angle Unequal 40x20 is a 6060 T5 mill-finish aluminium L-section with 40 × 20 mm unequal legs. The unequal 40 × 20 mm legs give a wider primary face with a shorter return where the two sides of the detail do not need the same coverage. It is stocked for general fabrication, caravan and vehicle body work, shopfitting, edge protection and framing details where this exact aluminium angle section suits the design.
| Leg dimensions | 40 × 20 mm |
|---|---|
| Geometry | Unequal angle |
| Alloy / temper | 6060 T5 |
| Finish | Mill finish |
| Current stock | 1.6 mm × 2165 mm or 3.0 mm × 2165 mm |
Choose the 1.6 mm section where a lighter profile suits the fabrication; choose 3.0 mm where the project calls for a more substantial section. This is section-selection guidance, not a structural load rating.
Cut with a suitable non-ferrous blade, deburr cut edges and drill, fasten or weld to the project fabrication detail. If the aluminium will be anodised, powder coated or painted, clean and prepare the mill finish for the selected coating system. Isolate the aluminium from incompatible dissimilar metals or treated timber where the project detail requires corrosion separation.
