Aluminum Pipe

Seamless & Welded Aluminum Pipe in 1100, 3003, & 6061 Grades

Action Stainless supplies aluminum pipe in 1100, 3003, and 6061 grades—each offering distinct performance benefits for architectural, industrial, and general fabrication use. Whether the need is for lightweight corrosion resistance, ease of forming, or structural strength, our inventory supports a wide range of applications.


1100 is best for low-pressure systems and decorative or chemical environments where workability is key. 3003 provides moderate strength and excellent weldability, ideal for trim, HVAC, and marine components. For load-bearing or mechanical applications, 6061 offers the highest strength of the three, along with outstanding weldability and durability.

Finishes & Processing Services

Aluminum pipe is supplied in a clean mill finish suitable for most structural and mechanical needs. For enhanced visual appeal or added corrosion protection, polished, brushed, and anodized finishes are available by request. Action Stainless also offers in-house processing services including precision cutting, threading, beveling, and CNC machining to ensure aluminum pipe is delivered installation-ready and tailored to your project requirements.
