L profile aluminum is a versatile aluminum extrusion profile widely used in construction, manufacturing, machinery, transportation, furniture, and industrial applications. Its simple 90-degree L shape provides excellent structural support while remaining lightweight, corrosion-resistant, and easy to fabricate.
At Youheng Aluminum, we supply customizable aluminum L profiles in different alloys, dimensions, wall thicknesses, surface finishes, and lengths to meet different project requirements.
What Is L Profile Aluminum?
L profile aluminum, also called an aluminum L profile, aluminum L shape profile, or aluminum angle extrusion, is an aluminum extrusion with an L-shaped cross-section.
The two legs of the profile can have equal or different widths depending on the application. Aluminum L profiles can be manufactured in various sizes and thicknesses, making them suitable for both decorative and structural applications.
Compared with steel angle profiles, aluminum L profiles offer a lower weight and good corrosion resistance while remaining easy to cut, drill, machine, and assemble.
Key Features of Aluminum L Profiles
- Lightweight construction
- Good corrosion resistance
- High strength-to-weight ratio
- Easy cutting and machining
- Suitable for welding and mechanical fastening
- Available in different aluminum alloys
- Customizable dimensions and lengths
- Available with different surface finishes
- Suitable for indoor and outdoor applications
Aluminum Extrusion Profile Manufacturing
Aluminum L profiles are commonly manufactured through the aluminum extrusion process.
During extrusion, an aluminum billet is heated and pushed through a specially designed die to create the required L-shaped cross-section. After extrusion, the profiles can be cut to length and processed according to the customer’s requirements.
Custom aluminum extrusion profiles can also be produced when standard dimensions do not meet a project’s requirements.
Aluminum L Profile 3000 Series
3000 series aluminum is mainly alloyed with manganese (Mn), offering a good combination of corrosion resistance, formability, and moderate strength. Common grades for aluminum profiles and related applications include 3003, 3004, 3005, and 3105.
3003 Aluminum L Profile

- Best for: General-purpose L profiles, trim, brackets, equipment components, and applications requiring easy fabrication.
3004 Aluminum L Profile
- Advantages: Higher strength than 3003, good corrosion resistance, good formability, and good weldability.
- Disadvantages: More expensive than 3003 and not suitable when very high structural strength is required.
- Best for: Applications requiring a stronger 3000 series aluminum profile while maintaining good formability and corrosion resistance.
3005 Aluminum L Profile
- Advantages: Good corrosion resistance, moderate strength, good formability, and good weldability.

Which 3000 Series Aluminum Is Best for L Profiles?
- 3003: Best for general-purpose and cost-sensitive applications.
- 3004: Better choice when higher strength is required.
- 3005: Suitable for applications requiring a balance of strength, corrosion resistance, and formability.
- 3105: Suitable for general construction and architectural applications where corrosion resistance and formability are important.
Important: The suitability of a specific alloy depends not only on the grade but also on the temper, profile dimensions, wall thickness, extrusion feasibility, and application requirements. For custom aluminum L profiles, the alloy should be confirmed before production.
Aluminum L Profile 6000 Series
6000 series aluminum is one of the most commonly used alloy families for aluminum extrusion profiles. It mainly contains magnesium (Mg) and silicon (Si) and offers a good balance of strength, corrosion resistance, machinability, and extrudability. Common grades include 6060, 6061, 6063, and 6082. The specific alloy should be selected according to the required strength, surface finish, extrusion complexity, and application.
6060 Aluminum L Profile
- Advantages: Excellent extrudability, good surface finish, good corrosion resistance, and easy machining.
- Disadvantages: Lower strength than 6061 and 6082.
- Best for: Decorative profiles, architectural trim, furniture, frames, and applications where appearance and extrusion quality are important.
6061 Aluminum L Profile
- Advantages: High strength, good corrosion resistance, good machinability, and good weldability. It is a versatile choice for structural applications.
- Disadvantages: More difficult to extrude than 6063, and its surface finish is generally not as smooth as 6063.
- Best for: Machine frames, brackets, structural components, transportation equipment, and other applications requiring higher mechanical strength.
6063 Aluminum L Profile
- Advantages: Excellent extrusion performance, excellent surface finish, good corrosion resistance, and good anodizing performance.
- Disadvantages: Lower strength than 6061 and 6082.
- Best for: Architectural profiles, decorative trim, doors and windows, furniture, frames, and general-purpose extrusion applications.
6082 Aluminum L Profile
- Advantages: Higher strength than 6060 and 6063, good machinability, and good corrosion resistance. It is one of the stronger commonly extruded 6000 series alloys.
- Disadvantages: More difficult to extrude and generally provides a less attractive surface finish than 6063.
- Best for: Heavy-duty structural components, machinery, transportation equipment, bridges, and applications requiring higher load-bearing capacity.
Which 6000 Series Aluminum Is Best for L Profiles?
- 6060: Best for complex extrusion shapes and decorative applications.
- 6061: Best when high strength and structural performance are required.
- 6063: Best when surface finish, anodizing, and appearance are priorities.
- 6082: Best for higher-strength structural and industrial applications.
Tip: For most architectural and general-purpose aluminum L profiles, 6063 is a popular choice because of its excellent extrudability and surface finish. For load-bearing or structural applications, 6061 or 6082 may be more appropriate. The final alloy and temper should be selected based on the required mechanical properties and application.
How Much Does an Aluminum L Profile Cost?
The cost of an aluminum L shape profile 3000 series depends on several factors rather than size alone.
The main factors include:
1. Aluminum Alloy
Different aluminum alloys have different material costs and mechanical properties.
2. Profile Dimensions
The width of each leg and wall thickness affect the amount of aluminum used per meter.
3. Profile Weight
For extruded aluminum products, price is often closely related to the weight per meter and total order quantity.
4. Surface Treatment
Anodizing, powder coating, polishing, and other finishes can increase the final cost.
5. Custom Extrusion Die
Custom profiles may require a new extrusion die. The die cost depends on the profile complexity and extrusion requirements.
6. Order Quantity
Wholesale orders generally have a different unit price structure from small trial orders.
7. Packaging and Shipping
For international orders, packaging, transportation, and destination-related logistics can also affect the final landed cost.
For an accurate quotation, buyers should provide the alloy, dimensions, quantity, surface treatment, and required delivery terms.

FAQ
How to Cut Aluminum Profile?
Aluminum profiles can be cut using suitable equipment such as a miter saw or cold saw equipped with a blade designed for aluminum.
For accurate cutting, secure the profile firmly before cutting and select the appropriate blade and cutting parameters for the alloy and profile thickness.
For large production orders, manufacturers can also supply aluminum profiles cut to the customer’s specified lengths.
How to Attach Wood to Aluminum Profile?
Wood can be attached to an aluminum profile using mechanical fasteners, screws, bolts, brackets, or suitable adhesives, depending on the application.
For a stronger connection, mechanical fastening is generally preferred for structural applications. The appropriate fastening method depends on the wood type, aluminum profile dimensions, load, and environmental conditions.
How to Fasten Aluminum Profile?
Aluminum profiles can be fastened using:
- Screws
- Bolts and nuts
- T-nuts
- Brackets
- Rivets
- Clamps
- Threaded inserts
The best fastening method depends on the profile design and the required load capacity.
For applications that require frequent assembly and disassembly, mechanical fastening systems are often more convenient than permanent joining methods.
