Square tube bearing capacity calculation formula

When calculating the bearing capacity of the square pipe, it is necessary to comprehensively consider the specification, material, span and strength of the square pipe. Here, we need to clarify what is "carrying capacity". The so-called bearing capacity refers to how much pressure the suspension span can withstand. For example, a 50*30*1.5 square tube is erected at both ends, and the middle is suspended for 1m. On this 1 meter span, a 50*30*1.5 square tube can place multiple items.

Generally speaking, according to the calculation of design drawings and construction drawings, then consider the specific square tube material (such as Q235 material or Q345 material). The square pipe material here needs to consider the specification and thickness of the square pipe, the material properties of the square pipe, the production process of the square pipe and the welding strength of the square pipe, which will affect the bearing capacity of the square pipe.
