我们一般使用较宽较厚的角铁，焊接一个口字去掉一竖的铁架子，包箱的上面、前面，下面，去掉安装卷帘门墙面的一道角铁，然后将卷帘门包箱的三个面固定在铁架子上。

Generally, we use a wide and thick angle iron, weld a word, remove a vertical iron shelf, remove a angle iron on the top, front and bottom of the box, and then fix the three sides of the box on the iron shelf.

在实际操作中，我们会根据卷帘门包箱的轻重程度，宽度，决定所使用铁架子的数量。铁架子数量如果过于少，也会出现下垂现象，铁架子数量过多，会增加材料人工成本，还影响使用效果。

If the number of iron shelves is too small, there will be sagging phenomenon. If the number of iron shelves is too large, it will increase the labor cost of materials and affect the use effect.
