Cold - formed steel characteristics

      Cold-formed steel refers to the use of steel or strip in the cold state into a variety of cross-sectional shape of the finished steel. Cold-formed steel is an economical section of light-weight thin-walled steel, also known as cold-formed steel profiles or cold-formed sections. Cold-formed steel is the main material to produce light steel structure. It has a hot-rolled can not produce a variety of special thin, reasonable and complex shape of the cross-section. Compared with the hot-rolled section steel, the radius of gyration can be increased by 50-60% and the cross-section moment of inertia can be increased by 0.5 to 3.0 times under the same cross-sectional area, and the strength of the material can be reasonably used. That is, from the traditional I-beam, channel, angle steel and steel production of steel structure) compared to savings of 30 to 50% of steel.
