Round tube lends itself well to bending because of the symmetry of the part and because the part can be encapsulated well with the proper tubing to avoid ovality or any other type of distortion. Generally speaking round tube bending is more difficult with a tighter bend. Also, the thinner the wall the more difficult. With the correct tooling, machinery and procedures, however, excellent quality can be achieved even with tight-radius, thin-wall round tube bending. Over the years we have seen a significant increase in the use of round tube bending in our work. The demand for bending aluminum round tubing has also increased.
We provide round tube bending from 3/8” diameter to 24” diameter and virtually every size in between, using dozens of machines and hundreds of die sets to bend round tubing. A variety of methods and techniques are used including rotary draw bending with mandrels, three-roll bending, four-roll bending, and compression bending. With these techniques these machines and this tooling, customers are seldom if ever given a tooling charge.
In addition to round tube bending, we also do ancillary operations including saw cutting, drilling, and welding.
Bent round tube is used in OEM applications like roll-over protection, framework, bumpers, and playground equipment. All kinds of structures now are built with round tubes that are bent: roofs, trellises, canopies, arches, balconies, and portals. We have also bent a considerable amount of round tubing for art.
