Cold formed steel

Steel pipe delivery status(condition) Cold forming is not heated in the case of material punching, bending and stretching of processing. Cold forming process are cold heading, cold-rolled, forging and so on.

Cold-formed steel refers to the use plates or strip bent in a cold state of the various cross-sectional shape of the finished steel. Cold-formed steel is an economical lightweight thin-walled steel cross-section, also called cold-formed steel profiles. Bending section steel is the main material of light steel structure. It has a hot rolling can produce all kinds of thin, reasonable shape and complex cross section.

Cold-formed steel is one of many varieties of steel in one, a certain width of the strip, under normal temperature conditions through a set of rolls arranged vertically, and gradually deformed, to meet the requirements of shape and size, and then cut into appropriate sizes length. This product is cold-formed steel. Of course, also has a stamping, bending or other deformation methods drawing cold-formed steel. But the roll forming method is suitable for high-volume industrial production, product quality, processing costs, production efficiency unmatched by other methods, is currently a major producer of cold-formed steel technology. If the unit is equipped with welding equipment in (such as high-frequency welding, welding, etc.) but also the production of cold-formed steel sections closed. Cold-formed steel and welded steel main differences are: welded steel pipes are mainly used for conveying fluids such as gas, water. Oil, gas, steam and so on. Requirements steel to withstand a certain pressure, and cold-formed steel is used to manufacture structures to withstand external force on beam cross-section shape, dimensions and mechanical properties have certain requirements.

main advantages of cold formed steel:
  1. compared with the thick hot-rolled steel, cold-formed steel can be processed into suitable smaller loads and shorter span.
  2. can be obtained economically unusual cross-sectional shape by cold forming, to obtain a satisfactory strength to weight ratio.
  3. considering the compact packaging and transport of produce can be nested section.
  4. no telescopic gravity environment becomes invisible.
