1-1/2″ x 3″ x .125″ wall aluminum rectangular tube is manufactured from 6063-T5 aluminum alloy and produced to ASTM B221 specifications for structural and architectural applications. The 1-1/2″ x 3″ profile combined with a .125″ wall thickness offers an excellent balance of strength, rigidity, and lightweight performance. 6063-T5 aluminum is valued for its smooth surface finish, good mechanical properties, and strong corrosion resistance, making this rectangular tube well suited for both functional and visual applications.

Applications:
1-1/2″ x 3″ x .125″ wall 6063-T5 aluminum rectangular tube is commonly used in architectural, structural, and fabrication applications, including:
• Frames, supports, and structural assemblies
• Architectural trim and decorative elements
• Railings, fencing, and handrails
• Sign frames and display structures
• Enclosures, guards, and light-to-medium duty frameworks
• General fabrication and custom aluminum projects

Advantages:
• Lightweight and strong: High strength-to-weight ratio reduces overall structure weight
• Corrosion resistant: 6063 aluminum performs well in outdoor and exposed environments
• Smooth, attractive finish: Ideal for anodizing or painting
• Good weldability: Compatible with common aluminum welding processes
• Dimensional consistency: Extruded profile provides uniform wall thickness and straightness

Summary:
The 1-1/2″ x 3″ x .125″ wall 6063-T5 aluminum rectangular tube is a versatile, durable, and corrosion-resistant structural material. Its combination of strength, clean appearance, and ease of fabrication makes it an excellent choice for architectural features, framing, and general aluminum fabrication applications.
