The most common profile pipes have dimensions 20*40, 40*40, 100*100. With such sizes, a combination of quality and strength is optimal. Profile pipes of square or rectangular cross -section have 4 stiffeners, but their weight is much smaller than the mass of a metal beam with similar sizes. It must be taken into account that the small mass of profile pipes does not affect bends or strength. Thus, profile pipes can be used in complex structures, significantly saving material. Profile metal pipes are used in many types of production. For example, in the furniture industry, with chemical and food production. They are used for the manufacture of various types of structures. In the production of technical documentation and to fulfill the necessary calculations, it will be necessary to know the weight of the profile pipe.
