Rectangular tubes are a category of structural steel, formed via the hot rolling process in a rectangular shape. These hollow shapes have precise dimensions based on the outside diameter (OD) and inside diameter (ID), or wall. Rectangular tubing has a box-like shape configuration that increases strength and rigidity compared to angles or channels—making it optimal for applications such as fabrication, and structural application.
Like the square tube, rectangular tubes are easy to weld, cut, form, and machine. Siskin Steel offers a comprehensive selection of rectangle tubing in standard sizes, ready to ship. Explore our range and use our custom processing services for tailor-made solutions.
