Cold-Formed Steel

cold-formed steel (cold rolled section steel) refers to the steel sheet or strip bent into various sections in the cold state The shape of the finished steel. Cold-formed steel cross-section of light is an economical thin-walled steel, also known as steel cold-formed sections or cold-formed profiles. The
cold-formed steel is the main material for the production of light steel structure. It has hot-rolled can not be produced by a variety of special thin, shape and complexity of the cross section. Compared with hot-rolled steel World Pipe network informed, in the case of the same cross-sectional area, radius of gyration can be increased from 50 to 60 percent, the moment of inertia can be increased from 0.5 to 3.0 times, and is thus more reasonable to use the strength of the material; with ordinary steel ( by the traditional I-beam, channel steel, angle iron and steel production, steel), compared to savings of about 30 ~ 50% of the steel World Steel Pipe News . In some cases, the amount of cold-formed steel structures steel reinforced concrete structure of the steel under the same conditions a considerable amount of an economic cross-section steel.
