The application of C-section steel can be said to be quite extensive. It can not only be used as purlin and wall beam in steel structure building, but also can be combined into lightweight roof truss, bracket and other building components. No matter what kind of use, it will involve the cutting of C-section steel. Due to different cutting methods have different cutting effect, it is necessary to select the appropriate one according to the requirements of customers.
Generally, if C-section steel is used in steel structure, its cutting should be carried out on shear machine or sawing machine as far as possible, especially for thin-walled steel roof truss.

The reason for this proposal is that the blanking should be accurate, and it is suitable for the electric sawing method, which is not only highly efficient, but also has smooth and smooth section, good quality and very small cutting error.
However, in order to improve the quality of gas cutting, a small diameter nozzle should be used as far as possible. After cutting, the hammer should be used to gently tap the cut to make the cut smooth and meet the requirements of various uses. Like other cold-formed steel, the problem of C-section steel in the production process is the problem of internal stress. Due to the large internal stress of the material, once put into use, it may deform, thus affecting its use effect.
There is no way to avoid the stress of C-section steel. In the process of uncoiling, rolling shear and closing coil of cold-formed C-section steel, certain internal stress will be increased. The main reason is that the cold-formed C-section steel has certain stress through mechanical forced deformation. In addition, if the cold-formed C-section steel is not sprayed with primer, the rust removal and passivation process will also release its internal stress, resulting in bending and torsion.
In the case of no way to avoid, only through reasonable operation to reduce the stress, as manufacturers and users, should also pay attention to this issue, to ensure that cold-formed C-beam can be widely used.
