Among all other steel pipes, round steel pipes are used more frequently. In the construction industry, these round steel pipes are used most widely. For building sewages and water pipes, these steel round pipes are used. According to the different applications, the round steel pipes have different diameters. Whenever, any customization is needed, these pipes can be customized very easily.

These steel pipes are available in different thickness, different diameter length, and in different quality. Generally, these rounded steel pipes have high corrosion resistance capacity, high deformability, high toughness and higher strength.

While measuring the diameter of a round steel pipe, the outside as well as the inside diameters should be measure separately. The difference between these two values, is the length of the diameter of the round steel pipe. The thickness of the wall of this type of pipes, determines the pipe size.

We also provide Stainless Steel Seamless Pipes
