Extruded Aluminum Square & Rectangular Tube

You can find 6061, 6063, and 6005 aluminum square and rectangle tube in our extensive inventory. Our extruded aluminum square and rectangular tube provides clean lines, tight corners, and consistent wall thicknesses for structural frames, equipment bases, enclosures, and architectural builds. We maintain accurate dimensions across standard sizes, so your assemblies fit without rework or field adjustments. Like all our standard aluminum extrusions and profiles, these products machine well, weld cleanly, and maintain dependable strength across demanding applications. If your project calls for cut-to-length pieces, drilled holes, or additional processing, we handle fabrication in-house and ship material prepared for installation.
