The application of C-section steel can be said to be quite extensive. It can not only be used as purlins and wall beams in steel structure buildings, but also be self-assembled into lightweight roof trusses, brackets and other building components. Whatever the use, the same problem will be involved, that is, the cutting of C-section steel. Because different cutting methods have different cutting effects, it is necessary to select appropriate cutting methods according to customer's requirements.

Generally speaking, if C-section steel is used in steel structure, its cutting should be carried out on the shearing machine or sawing machine as far as possible, especially for thin-walled steel roof truss. The reason for this suggestion is that it is the easiest to cut the material accurately, and the electric sawing method is the most suitable one. It not only has high efficiency, but also has smooth cross-section, good quality and very small cutting error.

Of course, C-section steel can also be cut by gas, but in order to improve the quality of gas cutting, it is better to use small-caliber nozzle, and tap lightly with a hammer after cutting, so that the cut is smooth and meet the requirements of various uses.
