Application of box columns

1. The specification numbers behind the box-type steel columns refer to: web height x flange width x web thickness x flange thickness.
2. Box-type steel pipe columns are generally composite columns, which are assembled from steel plates.
3. Circular steel pipe columns generally bear parts where the axial force or eccentric force is small, while the box-shaped steel pipe column can have a larger cross-section in one direction, which determines that it can be used in places where eccentric force is large. From a production point of view, the production of circular steel pipe columns is relatively simple, while the production of box-type steel pipe columns requires a large amount of welding and is easy to deform, which is more difficult than round steel pipe columns. Therefore, box-type steel pipe columns are mostly made of large diameter and thick walls. As a box-shaped steel pipe column, the advantages of square and rectangular tubes are: direct forming, low material cost, good material performance, high strength, and easy installation
4. From the perspective of quota, square steel pipe columns belong to the scope of "shaped steel columns", which means that their cross-sectional characteristics can be used directly without processing. Round steel pipe columns do not belong to the scope of shaped steel columns. Their cross-sectional characteristics need to be processed to form ordinary steel pipe columns. Generally speaking, the price of circular steel pipe columns is much lower than that of box-type steel pipe columns that require assembly and welding of steel plates because they do not require cross-section processing.
5. Steel pipe columns are generally steel structural columns composed of one or more steel pipes. Box columns are steel structural columns composed of multiple steel sections (square and rectangular pipes, angle steel, channel steel, and I-beam steel).
