C型钢经热卷板冷弯加工而成，壁薄自重轻，截面性能优良，强度高，与传统槽钢相比，同等强度可节约材料30%。也正是由于C型钢所具有的独特优点，所以C型钢广泛用于钢结构建筑的檩条、墙梁。当然，也可自行组合成轻量型屋架、托架等建筑构件。此外，还可用于机械轻工制造中的柱、梁和臂等。

C-section steel is processed by hot coil cold bending, with thin wall, light weight, excellent section performance and high strength. Compared with traditional channel steel, the same strength can save 30% of materials. Because of the unique advantages of C-section steel, C-section steel is widely used in purlins and wall beams of steel structure buildings. Of course, it can also be combined into lightweight roof truss, bracket and other building components. In addition, it can also be used for columns, beams and arms in mechanical and light industry manufacturing.

在C型钢的用途我们可以看出，它主要的是用于檩条这方面，也就是说，主要起固定作用。那如果只是一根根的檩条，也没有什么东西可固定住，那么它还能有作用吗?所以大部分情况下，都会进行打孔。加工生产线，可根据客户的需求独立开发设计模具、满足客户的定制需求。

In the use of C-section steel, we can see that it is mainly used for purlin, that is, it mainly plays a fixing role. If it's just purlins one by one and nothing can be fixed, can it still work? So in most cases, holes are punched. The processing production line can independently develop and design molds according to customer needs to meet customer customization needs.

那么C型钢是怎么打孔的呢？一般C型钢都是由C型钢成型机自动加工成型的。C型钢成型机根据给定的C型钢尺寸就可以自动完成C型钢的成型工艺。放料①——矫平②——成型③——定型④——矫直⑤——测长⑥——冲拉筋圆孔⑦——冲椭圆连接孔⑧——成型切断⑨从它的流程中我们可以看到，7、8环节是打孔的，而且还是机器自动完成的。也就是说，C型钢机是自动冲孔，自动切断的。如果是先前的设备，则是在冲床装上冲孔模具，就可打圆孔和长圆孔。

So how is C-beam perforated? Generally, C-section steel is automatically processed and formed by C-section steel forming machine. The C-section steel forming machine can automatically complete the forming process of C-section steel according to the given size of C-section steel. Discharging ① - leveling ② - forming ③ - setting ④ - straightening ⑤ - length measurement ⑥ - punching of drawbead round hole ⑦ - punching of elliptical connecting hole ⑧ - forming and cutting ⑨ from its process, we can see that links 7 and 8 are perforated and completed automatically by the machine. In other words, the C-beam machine is automatic punching and automatic cutting. If it is the previous equipment, the punch is equipped with a punching die to punch round holes and long round holes.
