Hollow section and solid section are both belonging to building profiles. But how can you choose from them?



In general, hollow sections are more suitable as structural steel than solid profiles. Because the hollow section has the characteristics of light weight, high moment of inertia and low material cost. However, for the same material size and load, a solid section will have stronger bending, tensile, and compressive forces.


The second moment of area of hollow square or rectangular or circular section is very close to a section with the same size. Alternatively, the same section area if used in a hollow section creates a larger second moment of area than a solid section.


If you're concerned about overall weight, choose hollow sections. If you are concerned about deflection, use a thicker-walled hollow section.
