Black Annealed CRC Coil SPCC cold Rolled Steel Sheet
Black annealed coils,Black Annealed CRC Coil SPCC cold Rolled Steel sheets coils is cold rolled continuous annealing plate, after a series of pickling, cold rolling, online continuous annealing, finishing and other processes and formed. It is the low carbon steel rolled into a thickness of less than 2.0mm steel plate, because the product through strict processing, so its mechanical properties and technology is far better than hot rolled thin steel plate, especially in the field of household appliances manufacturing.The cold-rolled continuous annealed coil plate produced by the company is widely used in various deep-drawing products, chain cover, metal containers, radiators, file cabinets, computer cases, wire mesh, steel and wood furniture, bright steel pipe, barrel making and other industries besides the base band of galvanizing and color drawing production.

Hot dip galvanizing steel C purlin for prefabricated buildings warehouse garage
C purlin is the main structure in the bulding , our products are in a good market in the world ! Cold-formed steel has been widely adopted as the main load-bearing component of the portal frame. However, they use a combination of public-shaped cross section in the door frame of the beam components, studies have shown that ,for small and medium span in the door frame, if we adopt single limb C steel used for beam-column elements, the construction of the node will be more concise, while it will be more convenient to components transportation, installation. C-beam flange width,nodes on the beam diameter bolts connecting nodes have little effect on bearing capacity and stiffness, while the material yield strength of the connected nodes bearing capacity and stiffness is relatively large.
