Aluminum Hollow Round Tubes

Aluminum Hollow Round Tubes

Our aluminum hollow round tubes are precisely extruded cylindrical profiles, specially designed for high strength, low weight and easy manufacturing. It features a wide range of outer diameters (OD), wall thicknesses and cutting lengths, making it the preferred solution for structural frames, furniture, displays, mobile products and thousands of engineering components. The style matches the shown image: clean circular external geometry, constant walls and smooth inner holes are ready for processing, punching and finishing.

Whether you need satin anodized anti-corrosion handrails, bright colors for retail fixtures, or tight tolerance tubes for mechanical parts, we can provide repeatable large-scale quality. In addition to extrusion, we also offer a complete range of downstream services - anodizing, powder coating, punching, drilling, slotting, deburring and precision cutting - so you can obtain ready-made assembled parts from a reliable source.

We offer factory integrated sorting lines to protect, beautify and distinguish your products.

1) Fully auto anodizing:

• Application: Electrochemical growth of a hard, transparent oxide layer integrated into the metal.
• Advantages: Excellent corrosion resistance, wear resistance, color stability and high-quality appearance/feel.
• Style: Transparent/silver, black, Champagne, bronze, gold, and custom colors.
• Texture: Matte, satin, brushed, or mechanical pre-treatment after brightening.
• Thickness: Typical 8-15 μm is used in construction; It can reach a maximum of 25 μm in harsh environments.

2) Powder coatings

• Application: Electrostatic spraying of thermosetting powder; Solidified: solidified for durability
• Advantages: ** Impact resistance, UV/weather durability, a wide range of gloss levels (matte to high gloss), and an unlimited color palette, including metallic and textured.
• Features: ** Anti-graffiti, anti-microbial and outdoor marine-grade system.
•  

3) Other modifications

The electrophoretic coating (E-coat) is a uniform film established on complex components.

Mechanical polishing/brushing to enhance decorative luster.

Chemical etching, shot blasting and transparent paint are used to achieve unique aesthetics and tactile sensations.

• System cost reduction: Weight savings reduce transportation, handling and overall system load; Integrated manufacturing reduces multi-supplier coordination and work-in-progress inventory.
• Design flexibility: Select alloys, walls, and complete the adjustment of stiffness, weight, appearance and corrosion resistance.
• Reliability: The coating system has been verified through thickness, adhesion and salt spray tests. 
• Scalability: From trial runs to high-volume production with multi-chamber molds and parallel lines.
• Shorter delivery time: Internal finishing and processing eliminate external queuing. The factory in Vietnam has increased regional production capacity close to global routes.

• Handrails, railings, guardrails and staircase systems
• Curtain wall pressure balancing pipes and curtain wall decoration
• Canopies, pergolas, signboards and lamp posts

Furniture and commercial equipment

• Table legs, sofa frames, wardrobe rods, display stands
• Use custom color storage fixtures, POP displays and suspension systems

Transportation

• Electric bicycle and scooter components, roof rack beams, shelves
• Interior grab bars, seat structures, and HVAC pipes of buses/trains

Industry and Machinery

• Frame, conveyor, pneumatic pipeline, protective cover
• Mechanical arms, fixtures/fixtures and test platforms require strict ID/OD control

• Solar installation hardware and outdoor casing

Sports, leisure and medical care

• Camping tent poles, hiking poles, photography equipment, fitness equipment
• Mobility AIDS (walkers, crutches) are placed where weight is most important

If you have unique use cases, our engineering team can recommend the best alloys, tempering and wall designs to balance stiffness, impact resistance and cost.

We focus on transforming your drawings into producible parts.

• Manufacturing-oriented Design (DFM) : Early involvement in the selection of outer diameter, wall and alloy; Tolerance Stack - ups;" Position of holes and slots And coating strategies. We suggest reducing costs while maintaining functionality.
• Molds and samples: Rapid mold design and test extrusion to verify cross-section, concentricity and surface; The color chip has completed the approval process.
• Process control: SPC of critical dimensions, maintained through cutting and punching. Traceability from raw materials to finished products.
• Color and surface treatment match: Anodized or powder-coated colors that comply with Pantone/RAL or brand standards; Gloss and texture control to achieve consistent aesthetics between batches.
• Packaging engineering: film packaging, interweaving, end cover protection, custom cartons, and recyclable racks to protect completion and speed up your assembly line.
• Documents: COA, material test report, RoHS/REACH declaration, and PPAP Level 3 for automotive/industrial customers if required.
• Logistics options: Integrated transportation, mixed packaging and regional inventory to support just-in-time plans.
• Minimum order quantity and delivery time: Flexible minimum order quantity, determined by OD and finished products. Typical delivery times include mold manufacturing, extrusion, finishing and manufacturing; With the production capacity of our factory in Vietnam, we can provide an expedited schedule.

Incoming materials: Chemical and hardness verification of billets; Batch control of coating powders and chemicals.

Work-in-progress: Dimensional SPC, concentricity inspection, roundness verification; Test of film thickness and adhesion of the coating; The selection procedure for salt spray or humidity aging.

Final inspection: 100% appearance screening of coated parts; AQL sampling in size; Functional gauge for perforation features.

Traceability: Through the batch number of the carton label and coa.

To expedite the quotation and sampling process, the following content is shared:

1. Outer diameter, wall thickness, length (or drawing)
2. Alloys/tempered (such as 6063 - T5, 6061 - T6) and mechanical target materials
3. Surface treatment (anodizing color and thickness or powder coating color/gloss/texture)
4. Processing: Hole size/position, grooves, tapping, special ends
5. Dimensional tolerance and surface grade (A surface /B surface)
6. Demand for annual rolls, packaging and labels
7. Port of destination or port of delivery

Our engineers can convert sketches into manufacturable drawings and recommend where to maintain strict tolerances and appearance tolerances - saving time and costs without affecting performance.

• One-stop capability: Extrusion, finishing and manufacturing in a single, quality-controlled workflow.
• Engineering partnership: Practical DFM input and rapid prototyping reduce risks and accelerate release speed.
• Consistent aesthetics: batch-to-batch color management, gloss control and surface uniformity.
• Global Footprint: The factory in Vietnam offers tariff preferences, fast and scalable supply.
• Customer-oriented service: transparent communication, clear documents, and on-time delivery.
