Wuxi Yansheng Technology Co., Ltd., established in 2017, is a leading manufacturer specializing in aluminum structural products. With a factory spanning 1,000–3,000 square meters and an annual export value of US$50–100 million, we deliver high-quality 6061 T6 Aluminum Structural Tubes designed for demanding construction and mechanical frame applications. Our seamless pipes combine exceptional toughness with lightweight properties, offering reliable performance in load-bearing structures. Backed by ISO9001, ISO14000, and other certifications, each tube undergoes strict quality control to ensure dimensional accuracy and consistent mechanical properties.
The 6061 T6 Aluminum Structural Tube is engineered for projects requiring high strength-to-weight ratio, corrosion resistance, and durability. Its seamless construction eliminates weld weak points, making it ideal for critical structural components. Whether you're building industrial racks, automotive chassis, or architectural frameworks, this tube delivers robust support with ease of fabrication.
Key Features & Benefits
High Toughness & Strength: T6 temper ensures yield strength of 276 MPa (typical) and ultimate tensile strength of 310 MPa, providing excellent load-bearing capacity.
Seamless Construction: No welded joints reduce stress concentration, improving fatigue life and uniform material properties.
Lightweight: Density of 2.7 g/cm³ reduces overall structure weight, lowering transportation and installation costs.
Corrosion Resistance: Natural oxide layer protects against atmospheric corrosion; optional anodizing enhances durability in harsh environments.
Excellent Machinability: Can be cut, drilled, welded, and bent with standard equipment, saving fabrication time.
Customizable Dimensions: Available in round, square, and rectangular profiles with custom wall thickness, length, and tolerances.
Consistent Quality: Certified under ISO9001, ISO14000, OHSAS18001, and QS9000 systems, with batch traceability.

Frequently Asked Questions (FAQ)
1. What is the difference between 6061 T6 and 6063 T5 aluminum tubes?
6061 T6 offers higher strength (yield ~276 MPa vs. 160 MPa for 6063 T5) and better toughness, making it suitable for structural frames. 6063 T5 is more extrudable and often used for decorative profiles.
2. Can these tubes be welded?
Yes, 6061 aluminum is weldable using standard TIG or MIG methods. However, post-weld heat treatment may be required to restore T6 properties in the heat-affected zone. We recommend consulting with a welding engineer.
3. Do you provide certificates of material and testing?
Absolutely. Each batch comes with a mill test certificate (MTC) showing chemical composition and mechanical properties. Third-party inspection (e.g., SGS, BV) is available upon request.
4. What surface treatment options are available?
Standard options include mill finish (with natural oxide), clear or color anodizing, and powder coating (RAL colors). Custom finishes like electrophoretic coating are also possible.
5. What is the minimum order quantity (MOQ)?
Our MOQ for stock sizes is 100 kg for round tubes and 200 kg for square/rectangular. Custom dimensions and profiles have MOQs starting from 500 kg.
6. How long does shipping usually take?
For standard sizes, production takes 15–20 working days, plus 20–40 days for sea freight depending on destination. Express air freight is available for urgent orders.
7. Can you supply tubes for marine environments?
Yes. 6061 T6 has good corrosion resistance, but for direct seawater exposure we recommend anodized or powder-coated finishes. We can also provide 5083 alloy for extreme marine applications upon request.
8. Do you offer custom cutting and drilling services?
Yes, we can precut tubes to exact lengths and drill holes or slots per your drawings. Additional machining services are available with consultation.
