Structural Square Hollow Tube - Rounded Corners

Our structural square hollow tube extrusions are design for structural use with rounded corners for extra strength.

They come in mill finish in 12’, 20’ and 24’ feet lengths, depending on the profile.

Please keep in mind that our industry standard square hollow tubes are not designed to fit together or inside one another. The only hollow tubes we guarantee will work together are our Telescopic Tubes.
