镀锌钢卷，除原有（宽）加工外，还有很多场合都是根据产品的需要进行加工来实现带材的使用。例如雨水槽、顶棚梁、百叶窗板、C.Z型钢等。此外，音响设备的外壳也可以用带钢卷连续冲压加工。
在分切过程中，必须特别注意弯曲问题。
尽管线圈看起来是直的，但有些线圈是轻微弯曲的。造成带钢卷弯的原因是多方面的，其中一个原因是由于钢卷在分切前的形状不好。例如，在延伸趋势较大的钢卷中心，该部分的长度会更长，带钢卷会弯曲。即使带钢卷本身没有电弧问题，产品在辊压成型时有时也会产生电弧。这是因为，如下图所示，在分切前，钢卷的中心部分较厚，而分切后，条形钢卷的横向板厚会不均匀。如果再次进行滚压成型工艺，则辊压差可能会导致产品产生电弧。特别是当电弧需要严格控制时，必须使用形状良好的钢卷，否则必须在钢带数量上下功夫防止电弧。
订购时，请与订购的小卷或小卷进行讨论。
所谓的弧度（横向弯曲）是指侧边与直线之间的偏差。在测量方法上，直尺靠近边缘来测量弯曲深度。

Galvanized steel coil, in addition to the original (wide) processing, there are many occasions are based on the needs of the products to be processed to implement the strip to use. For example, rain gutters, ceiling beams, louver panels, C.Z section steel, etc. In addition, the shell of sound equipment can also be processed by continuous stamping with strip steel coils.

In the process of slitting, special attention must be paid to the problem of bending.
Even though the coil looks straight, some of them are slightly curved. There are various reasons for the bending of strip steel coil, one of which is due to the bad shape of steel coil before slitting. For example, in the center of the steel coil with larger elongation tendency, the length of that part will be longer, and the strip steel coil will be curved. Even if there is no arc problem in the strip steel coil itself, the product will sometimes arc when roller forming. This is because, as shown in the figure below, before slitting, the central part of the coil is thicker, and after slitting, the transverse plate thickness of the Striped coil will be uneven. If the roller forming process is carried out again, the roller reduction difference may cause the product to arc. In particular, when the arc needs to be strictly controlled, the steel coil with good shape must be used, or efforts must be made on the number of strips to prevent arc.
In order to obtain the coil with good shape or small bending, it is important to specify it when ordering and discuss with the consignor.
The so-caled arc (transverse bending) refers to the deviation between the side edge and the straight line. In terms of measurement method, the straight edge is close to the edge to measure the bending depth.
