Aluminum Tubing 

Versatile Aluminum Tubing in Square, Rectangular & Round Shapes

Action Stainless stocks aluminum tubing in a variety of shapes and grades to support architectural, structural, and industrial fabrication. Known for its corrosion resistance, lightweight strength, and ease of fabrication, aluminum tubing is ideal for applications in transportation, marine, construction, and display systems.


We offer aluminum tubing in square, rectangular, and round profiles, with material available in 1100, 3003, and 6061 grades. Each alloy is engineered to meet specific performance and fabrication requirements.

Finishes & Processing Services

Aluminum tubing is supplied in a smooth mill finish that’s ready for welding, machining, or anodizing. For decorative or corrosion-critical applications, brushed and anodized finishes are available upon request. Action Stainless supports fabrication with in-house services including precision cutting, CNC machining, punching, notching, and forming. These processing options ensure aluminum tubing is delivered in ready-to-use condition, customized to your exact size and performance needs.
