Wall thicknesses range from 2.0 to 6.0 mm. All angles are supplied in the standard length of 6,000 mm. Aluminum cut to size service is available — specify your desired cutting lengths for accurate quotation. Refer to the dimension table on this page for the complete range of aluminum angle sizes.
Applications by Industry
Construction & Architecture: Aluminum angles serve as structural edge reinforcement in facade cladding, corner protection for plasterboard and drywall installations, and support brackets for suspended ceiling systems. Equal angles 40x40x3 mm and 50x50x4 mm are commonly specified as railing and balustrade uprights, while larger 80×80 and 100×100 mm angles function as primary structural bracing in lightweight steel-alternative framing.
Industrial Automation & Mechanical Engineering: In the Maschinenbau sector, aluminum L-profiles reinforce enclosure frameworks, serve as mounting brackets for pneumatic and electrical components, and form the structural skeleton of machine guards and safety barriers. Unequal angles are frequently specified where asymmetric load distribution requires a profile with different leg widths.
Solar & Renewable Energy: Aluminum angles function as mounting brackets, tilt adjusters and secondary support elements in photovoltaic substructures. Angles 30x30x3 mm and 40x40x4 mm are standard components in roof-mounted and ground-mounted solar arrays. See our PV profiles range for dedicated solar mounting sections.
Transport & Vehicle Manufacturing: Lightweight aluminum angle sections reinforce trailer body corners, cargo floor edges and vehicle superstructure joints, delivering structural rigidity at a fraction of the weight of equivalent steel angles.
Furniture & Interior Design: Aluminum angles are used as edge trims, shelf brackets and frame connectors in modular shelving systems, display stands and kitchen fit-outs. The 15x15x2 and 20x20x2 mm sizes are especially popular for decorative and furniture applications.
Agriculture & Greenhouse Construction: Corrosion-resistant aluminum angles support greenhouse glazing bars, irrigation pipe brackets and barn ventilation frameworks, operating maintenance-free in humid agricultural environments.
Material Comparison
EN AW-6060 vs EN AW-6063: Both alloys are suitable for angle profiles. EN AW-6060 offers wider extrudability and is the default for general-purpose angles. EN AW-6063 delivers slightly higher strength (Rm 215–245 MPa) and superior anodizing quality, making it preferable for visible architectural angles. EN AW-6082 provides significantly higher tensile strength (290–340 MPa) for heavy structural applications but is harder to extrude into complex shapes.
Aluminum vs steel weight: An aluminum angle 50x50x4 mm weighs approximately 1.06 kg/m, while an equivalent steel angle weighs about 3.06 kg/m — a 65% weight reduction. This saving directly reduces transport costs, simplifies installation handling and decreases static loads on supporting structures.
Aluminum vs stainless steel: Aluminum angles cost significantly less per kilogram than stainless steel equivalents and weigh 66% less. For non-marine atmospheric exposure, the corrosion resistance of anodized aluminum matches that of austenitic stainless steel at a fraction of the price.
Surface Treatment Options
Aluminum angles are supplied in mill finish (raw/walzblank) as standard. Optional treatments include anodizing in natural silver, black or bronze (per EN 12373), creating a durable oxide layer of 10–25 µm that enhances abrasion resistance and provides a decorative finish. Powder coating in any RAL colour is available on request for colour-matched architectural and furniture applications.
Quality & Certification
ULAMEX is an EN 1090 and ISO 3834-2 certified aluminum supplier. All aluminum angles are available with mill test certificate 3.1 per EN 10204, ensuring full material traceability from extrusion to delivery. Our certification ensures compliance with European structural construction requirements.
Frequently Asked Questions
What is the weight per metre of an aluminum angle?
The weight depends on the leg dimensions and wall thickness. For example, an equal aluminum angle 40x40x3 mm weighs approximately 0.62 kg/m, while a 60x60x5 mm angle weighs approximately 1.60 kg/m. You can calculate the weight using the formula: weight (kg/m) = cross-sectional area (cm²) × 2.70 (density of aluminum in g/cm³) / 10.
What is the difference between equal and unequal aluminum angles?
Equal angles have two legs of identical width (e.g. 50×50 mm), providing symmetrical load distribution for general framing and bracing. Unequal angles have legs of different widths (e.g. 40×20 mm), designed for applications requiring asymmetric support — such as stiffening a panel edge where one leg attaches to the panel and the other provides a narrower mounting flange.
Can aluminum angles be anodized?
Yes. EN AW-6060 T6 angles respond well to anodizing treatment. Standard anodized finishes include natural silver (clear), black and bronze. The anodized layer (typically 10–20 µm for architectural applications) provides enhanced corrosion protection, improved abrasion resistance and a decorative surface finish.
Are aluminum angles suitable for outdoor use?
Yes. EN AW-6060 T6 offers excellent natural corrosion resistance to atmospheric exposure. For extended outdoor use, anodizing is recommended to provide additional protection and maintain the appearance over decades. Mill-finish aluminum angles will develop a thin natural oxide layer that provides basic protection.
