Though a hollow bar looks like a pipe or a tube, they differ from the former components. Firstly, a Hollow Bar Supplier will recommend the use of these components for applications that require high strength. The thicker walls of hollow bars make them stronger and much harder than regular pipes or tubes. Most Hollow Bar suppliers will rightly assert that the strength of both round bars as well as a round carbon steel hollow bar would be similar.
However, the weight of both the components vary, with the hollow component having a lower weight per foot, without the need for any compromise with regards to its mechanical strength. Moreover, an added benefit of using hollow bars is that they cost lower in comparison to round bars, as the consumption of the metal is lower as well. Similar to pipes, a cast iron hollow bar could be measured by with the help of dimensions like its inner diameter or ID and outer diameter or as known as OD. Another point in common hollow bars have with pipes is that they can be processed in a similar manner. For instance, most suppliers are able to provide stainless steel hollow bar that has been machined either on the outside or the inside. In times where a corrosion resistant product is required, suppliers can also supply a galvanized iron or gi hollow bar.
