Aluminum round tubes are widely used in structural support, mechanical systems, framing, and piping applications. Their hollow circular cross-section provides uniform strength and stability, making them suitable for a broad range of construction, transportation, and industrial uses. With good corrosion resistance and machinability, they perform reliably in both indoor and outdoor environments.
We manufacture aluminum round tubes in both standard and custom sizes, using widely used alloys such as 6061 and 6063. Tubes are available in a variety of outer diameters and wall thicknesses, with customization options to suit structural, mechanical, or architectural applications.
Depending on project requirements, we can adjust alloy and temper to meet strength, formability, or corrosion resistance needs. From drawing review to final production, our team ensures each tube meets the specifications for framing, piping, fabrication, or general-purpose use.

Internal or external threading to support fasteners, pipe fittings, or mechanical connections.
Complex features like precision grooves, contours, or end modifications machined to tight tolerances.
Ends can be beveled or cleaned for TIG/MIG welding, especially in load-bearing or tubular frame structures.
All machined parts are deburred and smoothed to ensure safe handling and clean assembly.
Aluminum round tubes are used across architectural, structural, and mechanical applications where durability, corrosion resistance, and appearance are key. Surface finishing not only enhances visual quality but also protects the material from wear, oxidation, and environmental exposure. Based on usage scenarios—indoor, outdoor, or marine—we offer a range of finishing options tailored to performance and aesthetic needs.
Electrochemical process that creates a corrosion-resistant oxide layer with improved surface hardness. Ideal for architectural and outdoor use.

We provide integrated production services for aluminum round tubes, including extrusion, surface treatment, precision cutting and machining, and delivery of components ready for use in structural framing, mechanical systems, piping frameworks, and general engineering applications.
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 round 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 round tubes are widely used in structural frames, mechanical components, handrails, heat exchangers, pipelines (non-pressurized), furniture tubing, and marine or outdoor structures. Their round shape provides uniform strength in all directions, making them suitable for both support and flow applications.
6061 aluminum tubes offer higher strength and better machinability, ideal for load-bearing and mechanical parts. 6063 has better surface quality and corrosion resistance, making it more suitable for architectural or decorative uses. If welding and structural performance are critical, 6061-T6 is often the preferred choice.
Yes. Aluminum round tubes, especially in 6061 alloy, can be welded using TIG or MIG processes. Proper surface preparation is important to ensure strong, clean welds. 6063 is also weldable but is softer and may require different filler materials.
Yes. Aluminum naturally forms an oxide layer that protects it from corrosion. For enhanced resistance, especially in outdoor or marine environments, anodizing or powder coating can be applied. These treatments help prevent pitting, oxidation, and surface discoloration over time.
Yes. We offer cut-to-length service, as well as drilling, slotting, threading, and welding preparation based on customer drawings or requirements. This helps reduce on-site labor and ensures a better fit in assemblies.
An aluminum round tube is a hollow cylindrical profile made through extrusion, commonly used in structural, architectural, and mechanical applications. Its circular cross-section provides uniform strength in all directions, making it ideal for frames, supports, pipelines, and tubing systems. Available in various diameters and wall thicknesses, aluminum round tubes are lightweight, corrosion-resistant, and easily machined or welded.
Aluminum round tubes are used in a wide range of industries, including construction, transportation, furniture, marine, and industrial manufacturing. Common applications include handrails, frames, heat exchangers, piping for non-pressurized systems, signage supports, and structural connectors. Their balance of strength and light weight makes them especially suitable for load-bearing yet portable structures.
The most commonly used alloys are 6061 and 6063.
Aluminum round tubes are available in a wide range of outer diameters—from small tubing (e.g., 10 mm OD) to large-diameter structural tubes (e.g., 200 mm OD). Wall thicknesses typically range from 1.0 mm to 10.0 mm, with custom sizes available upon request. Thicker walls provide greater strength, while thinner options are used in lightweight or low-load applications.
To enhance durability, corrosion resistance, and appearance, aluminum round tubes can be treated with:
Yes. Aluminum round tubes—especially in 6061—can be TIG or MIG welded and are compatible with CNC machining, drilling, and threading. Proper surface preparation (such as oxide removal) is essential for quality welds. Thicker-walled tubes are preferred for structural welding, while thinner tubes may be used with mechanical fasteners.
Key factors include:
Yes. Aluminum round tubes are naturally resistant to rust and oxidation, especially when anodized or powder-coated. They are widely used outdoors for fencing, railings, signposts, and marine applications. For harsh or coastal environments, anodized finishes or marine-grade alloys are preferred to ensure long-term performance.
Depending on the alloy and wall thickness, aluminum tubes can be bent using proper tooling.
Aluminum tubes are significantly lighter than steel, corrosion-resistant without coating, and more durable than PVC. They require less maintenance and are easier to cut and machine. While steel offers higher raw strength, aluminum provides a better strength-to-weight ratio, easier handling, and a longer lifespan in outdoor or humid environments.
