Structural pipes are most often used for various types of building structures. For this type of pipe, the most important is the material strength and the static properties depending on the pipe profile. A steel pipe is considered an excellent construction element for a constructor due to the greatest use of the strength properties of the material. By selecting the appropriate wall thickness and the size of the pipe diameter, it is possible to obtain the lowest weight of the structure with the highest load resistance. That is why steel pipe is an indispensable structural element in all branches of the construction industry.
