In terms of current technology, C-section steel is automatically processed and formed by C-section steel forming machine. C-section steel is often used in construction engineering, so there are many problems about the deformation of section steel. Since it is automatic molding, what kind of situation will happen in the later stage?

之前有不少朋友反馈说，在建筑工地施工时，经常看到C型钢出现弯曲或是严重变形。但当时到货是没有问题的。C型钢加工过程中的一道重要工序，冷弯是C型钢成形的关键，冷弯之后还要对材料进行校正。即便如此，一段时间后C型钢还是会出现严重的变形情况。这也说明了C型钢中有很大的内应力存在，才使得C型钢弯曲之后还是会产生很大的回弹情况。

Many friends reported that they often saw the bending or serious deformation of C-section steel during construction on the construction site. But there was no problem with the arrival at that time. Cold bending is an important process in the processing of C-section steel. Cold bending is the key to the forming of C-section steel. After cold bending, the material must be corrected. Even so, after a period of time, C-section steel will still have serious deformation. This also shows that there is a lot of internal stress in C-section steel, which makes C-section steel still produce a lot of rebound after bending.

所以购买的C型钢要尽快使用，如需存放，要把不同种类的C型钢分开堆放,以方便取放和管理。为了保证C型钢质量，一定要找正规厂家。

Therefore, the purchased C-section steel should be used as soon as possible. If it needs to be stored, different types of C-section steel should be stacked separately to facilitate taking, placing and management. In order to ensure the quality of C-section steel, we must find regular manufacturers.
