From the history of the pipe, and we can see this type of pipe material through a complex period, from the beginning of the last century, the pipe has appeared, but at that time, the pipe has not been widely used, from the point of view of square tube stage of development, the development of this pipe materials can be divided into four stages, the history of square tubes, industrial processes and developing world has a very close relationship, that is, in a few hundred years development, square tube has been a breakthrough change, a good quality of this type of pipe material, uses in various fields is also very extensive.
  With the continuous passage of time, the development of the pipe has gradually become mature, which is a high strength pipe material, pipe from the installation of this analysis, we can see that this pipeline welding material the process is relatively simple, and different strength of the tube, have a specific type of welding, however, this type of pipe material, use in various industries are very broad, which is a relatively high-quality pipe materials, and the general type of pipe material compared dominance is self-evident square tube, square tube scope is very broad.
  Meanwhile, the pipe in many areas have been promoted and used, along with the development of the construction sector, square tube role to play in this area are starting to become more and more, at the same time, this type of pipe materials have no ordinary pipe material dominance, not just for use in the construction field, in the field of interior design, square tube is also a very practical piping materials.
