Aluminum square tubes are commonly used in structural framing, machine enclosures, modular assemblies, and architectural systems. Their uniform square cross-section provides excellent rigidity and easy alignment, making them suitable for a wide range of construction, industrial, and design applications. With corrosion resistance and good workability, they perform reliably in both interior and exterior environments.
We manufacture aluminum square tubes in both standard and custom sizes, using widely used alloys such as 6061 and 6063. Tubes are available in a range of widths and wall thicknesses, with flexible customization to suit structural, architectural, or modular framing applications.
Based on your project requirements, we can adjust alloy type and temper to achieve the desired balance of strength, machinability, and corrosion resistance. From technical drawing review to final production, our team ensures each square tube meets the specifications for frameworks, supports, enclosures, or general-purpose fabrication.

Tube ends can be chamfered, cleaned, or pre-fit for TIG/MIG welding in structural or load-bearing applications.
Post-processing for sharp edge removal and clean surfaces, ensuring safe handling and smooth fit.
Aluminum square tubes are used in both functional and architectural applications, where corrosion resistance, appearance, and durability are essential. Surface treatments enhance the tube’s performance in outdoor environments, improve resistance to wear and oxidation, and offer aesthetic consistency for visible installations. We offer several surface finish options tailored to specific application needs.
Electrochemical process that creates a durable oxide layer, improving corrosion resistance and surface hardness.
A colored, protective coating applied via electrostatic spraying and heat curing.
Abrasive blasting that roughens the surface for matte appearance or pre-treatment.
Raw, uncoated aluminum surface as extruded.
Mechanically applied linear grain finish for decorative or visible parts.
We provide integrated production services for aluminum square tubes, including extrusion, surface treatment, precision cutting and machining, and delivery of components ready for use in structural framing, support systems, modular assemblies, and general fabrication projects.
We support packaging according to your needs, such as outer boxes with your logo, customized profile packaging. If there is no special instructions, we will use our regular packaging.
Communication is the first step to start a project. Simply upload CAD drawings, product images or provide samples, and we will perform DFM analysis and provide you with a quotation.
After confirming the production details we will make the first sample for you, and once you are satisfied with the sample we will start the batch production of your project.
For aluminum square tube, stable profile quality is an important factor to ensure the success of the project. Quality is our manufacturing criterion.
We support ODM/OEM, provide one-stop aluminum profile production services, have a variety of standard aluminum profile specifications of extrusion dies, and produce your aluminum profiles according to demand with competitive price costs.
Aluminum square tubes are commonly used in structural framing, modular systems, furniture, fencing, machine guards, and general fabrication. Their straight edges and uniform geometry make them easy to assemble, weld, or bolt into square or rectangular frameworks.
6061 provides higher strength and is suitable for load-bearing or mechanical applications. It also offers excellent weldability and machinability. 6063 is more corrosion-resistant and has a smoother surface, making it ideal for architectural and decorative uses where finish quality is important.
Yes, aluminum square tubes—especially 6061 and 6063 alloys—can be welded using TIG or MIG methods. Proper cleaning and preparation are important for achieving strong, clean welds. Thicker walls are typically easier to weld without distortion.
Yes. Aluminum square tubes are naturally resistant to corrosion. For added protection in outdoor, coastal, or industrial environments, finishes such as anodizing or powder coating are recommended to protect against UV, moisture, and chemical exposure.
We offer aluminum square tubes in a wide range of outer dimensions—from 10 mm to 150 mm—and wall thicknesses from 1.0 mm to 10.0 mm. Custom sizes are available upon request, depending on your design or structural requirements.
Yes. We provide precision cut-to-length services, hole drilling, slotting, notching, and other machining options to match your design drawings. These services help reduce on-site work and improve assembly efficiency.
Available finishes include:
Mill finish (as-extruded, untreated)
Anodized (for corrosion protection and decorative finish)
Powder coated (for color and surface durability)
Brushed (for visible or design-oriented applications)
For standard sizes in stock, lead time is typically 10–15 days. For custom sizes or processed products, delivery is usually within 20–30 days depending on complexity and quantity.
An aluminum square tube is a hollow extruded profile with four equal-length sides and a consistent wall thickness. It offers strong resistance to bending and torsion while maintaining a lightweight structure. Its geometry makes it ideal for applications where rigidity and clean, right-angle structure are needed. Common uses include framing systems, support structures, machinery enclosures, furniture frames, and architectural detailing.
Aluminum square tubes are widely used in construction frameworks, automation equipment, modular structures, handrails, fences, signage systems, and general fabrication. Their clean lines and structural symmetry make them a preferred choice for both functional and decorative use. In industrial environments, square tubes are often used for brackets, machine guards, and support posts due to their stability and ease of assembly.
The most common alloys are 6061 and 6063:
Aluminum square tubes are available in a wide range of dimensions. Common outer widths range from 10 mm to 150 mm, with wall thicknesses from 1.0 mm to 10 mm. The selection depends on structural requirements, weight limitations, and visual design. Custom sizes can be produced based on specific drawings or load specifications.
Square tubes can be finished with several surface treatments to improve durability and aesthetics:
These options help meet the demands of indoor, outdoor, or high-traffic applications.
Yes. Aluminum’s natural corrosion resistance makes square tubes well-suited for outdoor installations such as gates, railings, signage posts, or structural framing. For marine or coastal environments, anodizing or powder coating is recommended to enhance protection against salt spray, humidity, and UV exposure.
Absolutely. Square tubes—especially in 6061 alloy—can be TIG/MIG welded and CNC machined with high precision. They are also suitable for drilling, tapping, and slotting. Proper welding preparation, such as oxide removal, is essential for strong, clean joints. The flat surfaces and consistent thickness of square tubes make them easy to work with in fabrication shops.
Key considerations include:
Yes. We offer services such as cut-to-length, hole drilling, slotting, notching, welding preparation, and surface treatment. Custom extrusion is also available for non-standard sizes or integration with specific systems. Whether for OEM production, construction systems, or modular assemblies, square tubes can be tailored to your design.
Aluminum square tubes offer an excellent strength-to-weight ratio, corrosion resistance, and versatility in processing. Compared to steel, they are easier to transport, handle, and machine. Unlike wood or plastic, aluminum does not warp, crack, or degrade under harsh conditions. These characteristics make it a durable and cost-effective solution for both structural and aesthetic applications.
