Square Steel Tubing
Square Steel Tubing
We offer squares ½” x 16ga through 16” x 5/8 wall.
This welded structural grade tubing is applicable for all structural applications, manufacturing, fabrication, and repairs. The square shape provides much more strength and rigidity in comparison to channels or angles, and it’s also easy to weld, form, and cut. Service Steel Warehouse stocks ready-to-ship, precut and mill lengths, and also offers cut-to-length services.
