C型鋼經熱卷板冷彎加工而成，壁薄自重輕，截面性能優良，強度高，與傳統槽鋼相比，同等強度可節約材料30%。也正是由于C型鋼所具有的獨特優點，所以C型鋼廣泛用于鋼結構建筑的檁條、墻梁。當然，也可自行組合成輕量型屋架、托架等建筑構件。此外，還可用于機械輕工制造中的柱、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型鋼的用途我們可以看出，它主要的是用于檁條這方面，也就是說，主要起固定作用。那如果只是一根根的檁條，也沒有什么東西可固定住，那么它還能有作用嗎?所以大部分情況下，都會進行打孔。加工生產線，可根據客戶的需求獨立開發設計模具、滿足客戶的定制需求。

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型鋼是怎么打孔的呢？一般C型鋼都是由C型鋼成型機自動加工成型的。C型鋼成型機根據給定的C型鋼尺寸就可以自動完成C型鋼的成型工藝。放料①——矯平②——成型③——定型④——矯直⑤——測長⑥——沖拉筋圓孔⑦——沖橢圓連接孔⑧——成型切斷⑨從它的流程中我們可以看到，7、8環節是打孔的，而且還是機器自動完成的。也就是說，C型鋼機是自動沖孔，自動切斷的。如果是先前的設備，則是在沖床裝上沖孔模具，就可打圓孔和長圓孔。

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.
