The 3 Main Differences Between Tube And Hollow Bars

If you’re employed in a field that needs steel equipment for foundation It can be very useful to understand what hollow steel bars are.

Hollow steel bars are more economical than conventional metal bar stock since they weigh less than metal bar, but it will still provide as much force as its counterpart in the form of a metal bar.

Continue reading to find out more about the difference between tubes or hollow steel bar.

Three main differences between Tube and Hollow Bars

Three key characteristics that differentiate tubes from hollow bar:

Manufacturing process

Manufacturing Process

To allow hollow and tube steel bars to acquire their various compositions, they need to undergo a distinct manufacturing procedure. Tube bars are made by slit coils made of base metal, which is then passed through the tube mill. This lets the tube be shaped into a variety of shapes, including square or round or even rectangular. Once the proper shape has been obtained, the tube goes through an elongation process by using an electrical resistance tool.

When you have a hollow bar of steel, in contrast tubes there’s no welding involved. Two different methods could be employed to make hollow steel bars. The first method is drilling and the second is known as centrifugal casting. The drilling process produces extremely precise dimensions for the part, and centrifugal casting produces an unfinished steel bar that is extremely strong and even.


Typically hollow steel bars constructed from two types of material such as bronze and stainless steel. Utilizing these two materials allows these steel bars possess an extremely precise dimensional tolerance.

In the case of tubes, it may be much more difficult to achieve the tight tolerances in dimensional dimensions to be achieved. This is due in large part in the way that welding is performed. If a company is not mindful when making this tube bar could produce a poor quality of product.

In this manner, that hollowed steel bars could occasionally result in a better high-quality product as there are no other welding process that are employed, while welding processes in tube bar could result in different types of crystal structures close to the welding zone. In the end, this can affect those mechanical qualities within the tube.

With the tube bar various kinds of materials are employed to create the tube that is welded. To make welded tubing, it is generally recommended to use an electrically-conductive material. When you’re making the steel bars that are hollow it is recommended to use stronger materials that are more durable. If the material is not strong enough however, you might need to employ the piercing technique to make an hollow bar.

These are just a few of the principal differences between hollow steel bars. The final decision on which to use is dependent with the bar’s use since neither a hollow bar nor a tube bar is less expensive or superior to the other.
