Aluminium Angle Unequal 40 × 20 has a 40mm face with a 20mm return, giving you twice as much coverage on one side of the corner as the other. It suits selected caravan body panels, shopfitting edges, trims and cladding interfaces where a 40 × 40mm equal angle would project unnecessarily onto the shorter side.
Choose this unequal profile to cover a wider exposed face while keeping the return compact. For two matching 40mm faces, use 40 × 40mm equal angle instead; for a wider main face, compare 50 × 25mm.
