Aluminum Square Tube

Aluminum Square Tube is an extruded, seamless tubing with squared inside and outside corners, offering uniform strength and a clean, modern appearance. Lightweight yet rigid, it is ideal for applications such as railing systems, frameworks, and enclosures where aesthetic consistency and structural performance are both important.

Aluminum Square Tubes in 6061-T6 and 6063-T52 alloys combine formability with corrosion resistance and moderate strength, making them excellent for both industrial equipment and architectural detailing. Whether used for furniture, support structures, or piping systems, these extrusions provide durable, lightweight solutions with clean lines and reliable performance.
