The application of C-section steel processing can be said to be quite extensive, which can not only be used as purlin and wall beam in steel structure buildings; It can also 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 processing. Because different cutting methods have different cutting effects, they need to be selected appropriately according to the requirements of customers.
Generally, if C-section steel processing is applied in steel structure, its cutting shall be carried out on shear machine or sawing machine as far as possible, especially for thin-wall section steel roof truss. The reason why Xiaobian suggests this is that the blanking here should be accurate, and the easy electric sawing method is suitable. It not only has high work efficiency, but also has smooth and flat section, good quality and very small cutting error.
What is the effect of C-section steel processing and cutting
C-section steel can also be processed by gas cutting, but in order to improve the quality of gas cutting, try to use small-diameter nozzle, and gently tap with a hammer after cutting to make the incision flat and meet the requirements of various uses.
Like other cold-formed sections, the problem faced in the processing and production of C-section steel is the problem of internal stress. Due to the large internal stress of the material, once it is put into use, it may deform, which will affect its use effect.
There is no way to avoid the stress of C-section steel processing. A certain internal stress will be increased in the process of uncoiling, rolling shear and closing of cold-formed C-section steel processing. The main reason is that the cold-formed C-section steel processing has a 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.
When there is no way to avoid it, we can only reduce the stress through reasonable operation. As manufacturers and users, we should also focus on this problem to ensure that the processing of cold-formed C-section steel can be widely used.
