GA’s Aluminium Unequal Angle is an asymmetric L-shaped structural profile with two legs of differing lengths, manufactured from high-grade 6063 aluminium alloy to BS EN 755 standards. Available from stock in mill (untreated) or natural anodised surface finish, unequal angles are the profile of choice wherever a design calls for different span widths or fixing dimensions on each leg.
The asymmetric leg geometry provides greater flexibility than an equal angle in structural, engineering, and bespoke fabrication applications — allowing designers and fabricators to bridge mismatched surfaces, accommodate different fixing spacings, or create stepped profiles, all from a single standard section. Stock lengths are 4000mm.
Should you require a powder coated finish or cut pieces, please contact our Sales Team.
N.B. Jig marks, up to 50mm in from each end (often less than this), can be apparent on anodised items. These marks can be cut away before fixing.
Shade variations can occur with anodised surfaces due to the reactive nature of this finishing process.

Design Flexibility: Differing leg lengths allow unequal angles to bridge mismatched surfaces, fix across different material thicknesses, or create stepped profiles that would be impractical with a symmetrical section — making them indispensable in bespoke engineering and general
Lightweight Structural Performance: Aluminium’s exceptional strength-to-weight ratio means unequal angle sections deliver reliable structural support at a 2/3rds fraction of the mass of equivalent steel profiles — reducing installation effort, transport costs, and the overall load placed on supporting structures.
Anodised Surface Markings Resistance: Our test data confirms that anodised profiles achieve up to four times greater resistance to surface marking compared with mill finish — an important advantage for exposed structural elements or installations subject to regular physical contact.
Outstanding Corrosion Resistance: The natural oxide layer inherent to aluminium makes unequal angles highly resistant to corrosion in marine, coastal, and high-humidity environments — eliminating the ongoing maintenance and re-treatment costs associated with steel alternatives.
Cost-Effective & 100% Recyclable: The adaptability of a single unequal angle section across multiple fixing configurations reduces the need for additional components. Combined with aluminium’s full recyclability without loss of mechanical properties, these profiles deliver strong whole-life value.
