Aluminium Unequal Angle

Aluminium Unequal Angle

Alument Industries manufactures aluminium unequal angles — L-shaped profiles with legs of different lengths — designed for specialized structural, framing, and trim applications where standard equal-leg angles are not suitable. Our unequal angles are precision-extruded from 6063-T5 aluminium alloy to ensure consistent cross-sectional dimensions, clean corners, and smooth surfaces throughout the entire length. Unequal aluminium angles provide unique design flexibility, allowing engineers and fabricators to address asymmetric load requirements, create stepped transitions, and achieve specific aesthetic effects that equal angles cannot deliver. The difference in leg length makes them particularly useful for joining surfaces at different levels, creating shadow lines in facades, and providing directional stiffness in lightweight structures. Alument Industries offers aluminium unequal angles in a broad range of size combinations, from small trim profiles at 15mm x 10mm up to heavy structural sections at 100mm x 50mm. All profiles are available in mill finish, anodized, or powder-coated options, and custom dimensions can be manufactured to order for project-specific requirements.

Key Features

• Material: Premium 6063-T5 aluminium alloy
• Unequal leg lengths for specialized structural applications
• Wide size range: 15x10mm to 100x50mm
• Sharp, clean corners with tight radius tolerances
• Lightweight — significantly lighter than steel unequal angles
• Corrosion-resistant for indoor and outdoor use
• Available in mill finish, anodized, and powder-coated options
• Custom leg-length combinations available on request
• Easy to cut, drill, and fabricate on site
• ISO 9001:2015 certified quality assurance

Applications

Aluminium unequal angles are used in window and door framing, curtain wall mullions, stepped transitions in cladding, aircraft and automotive structures, solar panel mounting systems, marine fabrication, display stands, and industrial equipment frames. Their asymmetric profile makes them indispensable in applications requiring directional stiffness or joining of surfaces at different planes.
