Aluminum Rectangle Tube

What Is an Aluminum Rectangular Tube

 

An aluminum rectangular tube is an extruded hollow profile characterized by its asymmetric rectangular cross-section. Unlike square or round pipes, the rectangular shape offers superior bending resistance and stiffness along its longer axis, making it a highly efficient load-bearing component while minimizing overall weight.

 

Available in a variety of alloys, the most common are the 6063 (architectural grade) for excellent anodizing finishes and the 6061 (structural grade) for heavy-duty framework. These tubes can be extruded with sharp corners for seamless joining or radius (rounded) corners for enhanced safety and stress distribution.

 

Thanks to aluminum's natural corrosion resistance, these tubes are indispensable across multiple industries. Typical applications include architectural curtain walls, automated machine enclosures, solar panel mounting structures, marine vessels, and lightweight trailer frames.

Why Choose GNEE for Your Aluminum Rectangular Tubes?

 

1. Precision CNC Cutting

Stop wasting your internal labor hours and machining costs cutting standard 6-meter tubes. Equipped with advanced automatic double-head CNC saws, we provide exact cut-to-length services (e.g., 500mm, 1200mm). We guarantee tight length tolerances (±1mm) and deliver perfectly flat, burr-free ends. Your rectangular tubes will arrive ready to be dropped straight into your welding fixtures or automated assembly lines.

2. Export Packaging

Because rectangular tubes have wide, flat surfaces, they are highly susceptible to friction scratches and "white rust" (oxidation) during long ocean transits to the Middle East or Southeast Asia. We implement a strict, fail-safe packaging protocol:

  • Interleaving: Every individual tube is separated by EPE pearl cotton foam to prevent metal-to-metal rubbing.
  • Waterproof Wrapping: Bundles are tightly sealed in heavy-duty waterproof kraft paper and multi-layer plastic film with desiccants.
  • ISPM-15 Wooden Cases: Finally, they are packed into fully enclosed, fumigated wooden cases—never just strapped to open pallets. This guarantees zero crushing damage during heavy port handling.

3. 100% Traceability with Free MTC

Never gamble with structural integrity. Every batch of aluminum billets undergoes strict OES spectrometer testing before extrusion to ensure the exact chemical composition. With every shipment, we provide a certified EN10204 3.1 Mill Test Certificate (MTC) along with your commercial documents, giving your engineers and quality control teams absolute peace of mind.

Frequently Asked Questions
 

 

① What is the difference between 1060 and 6061 rectangular tubes?

Answer: They serve completely different industries due to their mechanical properties:
1060 (Commercial Pure Aluminum): Contains 99.6% aluminum. It has low mechanical strength but exceptional electrical and thermal conductivity. It is primarily used for electrical busbars, heat exchangers, and chemical equipment.
6061 (Structural Alloy): Alloyed with Magnesium and Silicon, and typically supplied in a T6 temper. It offers high yield strength (up to 275 MPa) and excellent machinability, making it the standard choice for load-bearing frameworks, machine bases, and trailer structures.

② What is the difference between an aluminum rectangular tube and a square tube?

Answer: The difference lies in the cross-section and mechanical efficiency. A square tube has equal sides, distributing loads evenly in all directions (ideal for columns or posts). A rectangular tube (e.g., 50x100mm) has an asymmetric shape, providing a much higher moment of inertia along its longer axis. This makes rectangular tubes significantly more resistant to bending and sagging when used as horizontal beams, joists, or heavy-duty supports.

③ What sizes and wall thicknesses can GNEE produce?

Answer: We operate extrusion presses ranging from 800 to 3,500 tons, allowing us to produce a vast range of dimensions.
Cross Section (W x H): From small 10x20mm profiles up to massive 200x400mm structural beams.
Wall Thickness (WT): Ranging from 0.8mm up to 35mm.
Standard Lengths: 5.8 meters (for 20ft containers) and 6 meters (for 40ft containers).

④ What are your standard production lead times?

Answer: We pride ourselves on stable and fast delivery.
For standard sizes (like 6061/6063) utilizing our existing dies and stock billets, production takes 7 to 10 days.
For custom dimensions that require opening a new extrusion die, or for large-volume orders (>20 tons), the lead time is typically 15 to 25 days after deposit receipt.

⑤ Do you provide an MTC (Material Test Certificate)?

Answer: Yes. Material traceability is standard practice at GNEE. An EN 10204 3.1 MTC, detailing the precise chemical composition and mechanical test results (tensile strength and yield strength) of your specific batch, is provided free of charge with every order.

⑥ Can you manufacture custom cross-sections (OEM profiles)?

Answer: Absolutely. If your project requires a non-standard dimension, a specific corner radius (rounded corners), or internal reinforcing webs, simply send us your CAD drawing. Our tooling department will design and cut a custom extrusion die within 7-10 days.

⑦ What surface treatment options do you offer?

Answer: To meet both functional and aesthetic requirements, we offer:
Mill Finish: The raw, as-extruded silver finish (standard).
Anodizing (Clear/Silver/Black): Creates a highly durable, corrosion-resistant oxide layer (10-25 microns thick), highly recommended for humid environments like Southeast Asia.
Powder Coating: Provides excellent UV resistance in any custom RAL color, perfect for architectural facades.
Sandblasting: For a premium, matte cosmetic finish.
