Aluminum Rectangular Tube Introduction
Aluminum rectangular tubes are lightweight, high-strength extruded profiles designed for both structural and decorative applications. Made primarily from alloys such as 6061-T6 and 6063-T52, these tubes offer excellent corrosion resistance, superior weldability, and a smooth surface finish suitable for anodizing or powder coating. The rectangular shape provides strong load-bearing capability while keeping weight low, making it ideal for frames, supports, railings, furniture, machinery parts, and architectural projects.
Common dimensions range from 1″×1/2″ to 6″×12″, with wall thicknesses between 1.2 mm and 6.35 mm. Standard finishes include mill finish, clear or colored anodized, powder coated, and brushed. All tubes are produced in accordance with ASTM B221 or ASTM B210 standards to ensure consistent mechanical performance and dimensional accuracy.
Aluminum rectangular tubes are widely used in construction, transportation, industrial equipment, and furniture manufacturing, offering a balance of strength, versatility, and aesthetic appeal. Custom lengths and finishes are available upon request, making them a reliable solution for various design and engineering applications.

What Are Aluminum Rectangular Tubes Used For?
Aluminum rectangular tubes are widely used in both structural and decorative applications due to their excellent strength-to-weight ratio, corrosion resistance, and clean appearance. They are commonly applied in architectural structures, such as window and door frames, curtain walls, handrails, and facade systems. In industrial and mechanical engineering, they are used to build machine frames, support structures, workstations, and equipment enclosures.
Because of their rigidity and easy fabrication, aluminum rectangular tubes are also ideal for automotive and transportation components, including vehicle frames, trailers, and roof racks. In furniture manufacturing, they serve as lightweight yet durable materials for tables, chairs, and shelving. Additionally, anodized or powder-coated rectangular tubes are popular in decorative and interior design projects, offering a modern, polished look.
Overall, aluminum rectangular tubing provides a versatile solution for construction, manufacturing, and design industries where strength, durability, and aesthetic appeal are required.
What Are the Characteristics of Aluminum Rectangular Tube?
Aluminum rectangular tubes feature a combination of lightweight strength, corrosion resistance, and excellent workability, making them a versatile choice for many industries. They are typically produced from high-quality alloys such as 6061 and 6063, which provide good mechanical strength, high toughness, and reliable weldability. The rectangular cross-section offers superior bending and torsional rigidity, making it ideal for structural and load-bearing applications.
These tubes are also known for their smooth surface finish and excellent anodizing performance, allowing various surface treatments such as anodizing, powder coating, or polishing to enhance both durability and appearance. They are easy to cut, machine, and form, which simplifies assembly and customization.
Complying with international standards like ASTM B221 and EN 755-9, aluminum rectangular tubes ensure consistent dimensional accuracy and performance. In summary, they combine strength, low weight, corrosion resistance, and aesthetic appeal, making them suitable for architectural, industrial, automotive, and decorative uses.
