Formed steel refers to a finished steel product of various cross-sectional shapes bent by a steel plate or strip steel in a cold state. Cold-formed steel is an economical thin-section thin-walled steel, also known as steel-refrigerated curved or cold-formed profiles. Cold-formed steel is the main material for making lightweight steel structures. It has a variety of extremely thin, well-shaped and complex sections that cannot be produced by hot rolling. Compared with hot-rolled steel, the radius of gyration can be increased by 50-60% and the moment of inertia of the section can be increased by 0.5-3.0 times in the same cross-sectional area so that the material strength can be used reasonably; That is to say, the steel structure made of the traditional I-beam, channel steel, angle steel, and steel plate can save about 30 to 50% of the steel.
