Steel Rectangular Tube

Rectangular tubing is a type of hollow structural section (HSS) with a rectangular cross-section, sometimes called a box section. A steel sheet or coil is stamped into a rectangular shape with stamping dies and then welded together on the inside where the two edges meet. Its shape provides more strength than angles or channels, while still being easy to weld and cut. These properties make rectangular steel tubing ideal for applications such as structural support, general fabrication, manufacturing, and repairs.

We offer a variety of ready-to-ship rectangular tubing sizes, from 2 x 1 x 16ga through 20 x 12 x 5/8” (or 2 x 1 up to 20 x 12, wall thickness 16ga up to 5/8” wall), as well as new Jumbo Rectangular Tubing. Our rectangular tubing inventory comes in precut and mill lengths or custom cut to your specifications, with other finishing services available.
