![]() ![]() In most instances, rectangular tube is bent either the “hard way” (x-x axis) or the “easy way” (y-y axis). It is usually the case, however, that even though more pressure is required to produce a bend the hard way, the resulting curved rectangular tube is less likely to distort precisely because it is more rigid than a section curved the easy way. Easy way rectangular tube bending is more likely to produce a somewhat concave inside diameter. For this project, Chicago Metal Rolled Products (CMRP) provided 14” x 4” x 3/8” bent rectangular tubing that was rolled to inside radii from 17’ to 21’, with a 10.9° pitch. Unlike round tubing, however, rectangular tubing can be rolled “off-axis,” as in the case of the Little Village Academy (see photo below). Similarly, bending rectangular tubing with thinner walls is more difficult than bending thicker walls (provided the bending machine has the power to curve the thicker sections). As with almost all metal bending processes, the tighter the bend, the more difficult it becomes.
