What is a "cold-formed square steel pipe" used as a column material in steel frame construction?
High-standard columns! An explanation of the differences in characteristics and applications based on manufacturing methods and standards.
Cold-formed square steel pipes are, as the name suggests, steel pipes that are formed into a square shape at room temperature. They are mainly used as column materials in steel structures. The characteristics and applications vary depending on the manufacturing methods and standards, and this time we will explain these differences. STKR and BCR are produced through roll forming. In particular, BCR has the advantage of being able to respond more easily to delivery requests due to its production based on forecasts. Additionally, BCP is manufactured through press forming and can accommodate large sizes. The properties of the flat plate section change very little from the base material, and it is characterized by having the same mechanical properties as SN materials. *For detailed information on the columns, please refer to the PDF document.
