Can choose the channel, steel rolling or welding H steel etc.. According to the load and the bearing condition, the cross section height is usually between the 1/20~1/50 of the span. The complex calculation of the overall stability of the steel beam can be avoided when the flange width is determined according to the l/b value of the space of the lateral support of the beam. The section height and the width of the flange, the plate thickness according to the provisions of local tectonic stability prediction.

Column section by the ratio of length and diameter ratio. Usually 50< λ <150, and the simple selection is near 100. According to the axial compression, bending or bending under the direction of the different, can choose the steel pipe or H steel section, etc..
Beginners should pay attention to the different structure, the specification of the structural requirements of the cross section is very different. The local stability of the plate part of the component which is unique to the light steel structure. There is a big difference between the standard and the light gauge steel.
In addition, the choice of the form of the member cross section has no fixed requirement, the light steel structural engineer should be based on the stress of the component, reasonable choice of the safety of the economic aesthetic section.
