C型钢的应用可以说是相当广泛的，不仅可以作为钢结构建筑中的檩条、墙梁，还可以组合成轻质屋架、支架等建筑构件。不管是什么用途，都会涉及到C切割型钢。因为不同的切割方法有不同的切割效果，所以需要根据客户的要求进行适当的选择。一般来说，C如果在钢结构中使用型钢，应尽量在剪切机或锯床上进行切割，尤其是薄壁型钢屋架。

The application of C-shaped steel can be said to be quite extensive, not only as purlins and wall beams in steel structure buildings, but also as building components such as lightweight roof trusses and brackets. No matter what the purpose is, it will involve C-cut steel. Because different cutting methods have different cutting effects, it is necessary to make appropriate choices based on customer requirements. Generally speaking, if section steel is used in steel structures, it should be cut as much as possible on a shear or saw machine, especially for thin-walled steel roof trusses.

之所以有这样的建议，是因为这里的下料要准确，适合电锯切割，不仅效率高，而且截面光滑平整，质量好，切割误差很小。C型钢也可以气割，但为了提高气割质量，尽量使用小直径喷嘴，切割后用锤子轻轻敲击，使切口平整，满足各种用途的要求。和其它冷弯型钢一样，C型钢生产过程中的问题是内应力。由于材料内应力大，一旦投入使用，可能会变形，影响其使用效果。

The reason for this suggestion is that the cutting here should be accurate and suitable for electric saw cutting. It not only has high efficiency, but also has a smooth and flat cross-section, good quality, and minimal cutting error. C-shaped steel can also be gas cut, but in order to improve the quality of gas cutting, small diameter nozzles should be used as much as possible. After cutting, gently tap with a hammer to make the cut flat and meet the requirements of various applications. Like other cold formed steel, the problem in the production process of C-shaped steel is internal stress. Due to the high internal stress of the material, once put into use, it may deform and affect its effectiveness.

济南C型钢厂认为，其C型钢无法避免型钢的应力。在冷弯中C在型钢开卷、滚剪、闭卷等过程中，会增加一定的内应力，主要是机械强制变形导致冷弯C型钢有一定的应力。另外，冷弯C如果型钢没有喷涂底漆，除锈和钝化过程也会释放其内应力，导致弯曲和扭转。在无法避免的情况下，只能通过合理的操作来减少应力的产生。作为制造商和用户，我们也应该注意这个问题，以冷弯曲C型钢可广泛应用。

Jinan C-beam steel plant believes that its C-beam cannot avoid the stress of the beam. In cold bending, C increases internal stress during the process of uncoiling, rolling shear, and closing of the section steel, mainly due to mechanical forced deformation, resulting in a certain amount of stress in the cold-formed C-section steel. In addition, if the cold-formed C steel is not coated with primer, the rust removal and passivation process will also release its internal stress, leading to bending and torsion. In unavoidable situations, stress can only be reduced through reasonable operations. As manufacturers and users, we should also pay attention to this issue, as cold bent C-beams can be widely used.
