- 6063-T5 Aluminum Construction
- ASTM B241 Certified
- 27,000 PSI Tensile Strength
- Excellent Corrosion Resistance
6063-T5 aluminum, often called 'architectural aluminum,' is an alloy of magnesium and silicon known for its exceptional surface finish and corrosion resistance. Manufactured as a seamless extruded pipe per ASTM B241 standards, it provides uniform strength and dimensional consistency. The T5 temper indicates artificial aging for increased hardness and strength after the extrusion process, making it a reliable, low-maintenance material.
As a large-format pipe with a 3-inch nominal size, this product is ideal for applications requiring significant structural integrity or flow capacity. Common uses include main water lines, industrial process piping, structural columns in buildings and signage, and large-diameter handrail systems for commercial or public works projects.

Applications
- Architectural & Construction: Structural columns and supports - its high strength-to-weight ratio and corrosion resistance are ideal for load-bearing aesthetic elements.
- Industrial Piping: Low-pressure fluid and air conveyance - large internal diameter allows for high volume flow in process systems.
- Marine Fabrication: Heavy-duty boat railings and tower frames - excellent resistance to saltwater corrosion.
- Infrastructure: Signage posts and guardrails - durable for outdoor use and can be finished for high visibility and longevity.
Target Users
Engineers, fabricators, and construction managers rely on 6063-T5 Aluminum Pipe for its combination of structural reliability and superior finish in architectural and industrial projects throughout the Los Angeles area.
Finish Options
This product comes standard with a mill finish, displaying a smooth, semi-matte surface characteristic of the extrusion process. For specific project requirements, other finishes such as anodizing or powder coating may be available via special order. Contact our Los Angeles sales team for custom finish inquiries.
How to Measure
Pipe is measured by its Nominal Pipe Size (NPS) and Schedule. NPS is a standard for pipe sizes, and the schedule determines the wall thickness. The actual outside diameter is 3.5 inches for a 3" NPS pipe.
Example: To order this pipe, specify "6063 Aluminum Pipe, 3-inch NPS, Schedule 40".
