Aluminum Angle is an L-shaped structural profile designed for lightweight support, reinforcement, and framing applications. It combines excellent corrosion resistance with good strength and fabrication performance, making it suitable for construction, machinery, transportation, and custom projects.
Available in alloys such as 6061 and 6063, aluminum angles are easy to cut, weld, drill, and assemble while maintaining long-term durability in indoor and outdoor environments.
Aluminum angle (also known as aluminum angle bar or L-shaped aluminum profile) is one of the most widely used extruded structural profiles in modern construction, architectural framing, and machinery manufacturing. Combining light weight with exceptional structural rigidity, outstanding corrosion resistance, and high strength-to-weight ratio, these extrusions provide reliable framing, bracing, and support solutions without adding unnecessary dead weight to assemblies.
At XQJ Metal, we manufacture and supply premium extruded L-shaped bars in both equal leg and unequal leg configurations. Produced in strict compliance with ASTM B221 and EN 755 standards, our structural angles are available in alloys like 6061-T6 and architectural alloys like 6063-T5, with custom cutting, punching, drilling, and anodized surface treatments tailored to your exact drawings.

Q1: What is the difference between 6061 and 6063 structural angles?
A: 6061 alloy offers higher mechanical strength and yield point, making it ideal for structural load-bearing frames. 6063 alloy offers superior surface finish and anodizing quality, making it preferred for architectural and decorative framing.
Q2: What is the difference between equal and unequal leg profile options?
A: Equal leg options have legs of the same width (e.g., 50mm x 50mm) at a 90-degree angle, providing symmetrical support. Unequal leg options have legs of different widths (e.g., 50mm x 25mm), designed for specialized directional structural bracing and space-saving framing.
Q3: What is your Minimum Order Quantity (MOQ) for custom extrusions?
A: Our standard MOQ is 500 kg per size for custom profiles. Smaller trial batches or cut sample pieces can be supplied for inventory stocked dimensions.

Our materials support a wide range of construction and infrastructure projects
6061 aluminum angle provides higher strength and is commonly used for structural applications, while 6063 aluminum angle offers a smoother surface finish and is preferred for architectural and decorative projects. The appropriate alloy should be selected according to the project's structural and aesthetic requirements.
Aluminum angle offers a combination of corrosion resistance, lighter weight, and easier handling compared with carbon steel. It is commonly selected where reducing weight and minimizing maintenance are important design considerations.
Aluminum angle is widely used for equipment frames, support brackets, architectural structures, solar mounting systems, shelving, and other lightweight structural applications. The appropriate alloy, temper, and dimensions should be selected according to the required load capacity and service environment.
It offers excellent resistance to seawater corrosion and maintains strength in humid and salt-rich conditions.
No. Strength is achieved through strain hardening rather than heat treatment.
Yes. It provides excellent weldability for structural fabrication.
Yes, it is commonly applied in tanks and pressure equipment.
Yes. It provides higher strength compared with most non-heat-treated aluminum alloys.
Yes. Thickness, width and temper can be adjusted based on project demand.
