濟南卷簾門(mén)

Jinan rolling shutter door

我們一般使用較寬較厚的角鐵，焊接一個(gè)口字去掉一豎的鐵架子，包箱的上面、前面，下面，去掉安裝卷簾門(mén)墻面的一道角鐵，然后將卷簾門(mén)包箱的三個(gè)面固定在鐵架子上。

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.

在實(shí)際操作中，我們會(huì )根據卷簾門(mén)包箱的輕重程度，寬度，決定所使用鐵架子的數量。鐵架子數量如果過(guò)于少，也會(huì )出現下垂現象，鐵架子數量過(guò)多，會(huì )增加材料人工成本，還影響使用效果。

In actual operation, we will determine the number of iron shelves to be used according to the weight and width of the rolling door box. 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.

在安裝卷簾門(mén)包箱的時(shí)候，在鐵架子與墻面的接觸點(diǎn)選擇適當高度來(lái)調節包箱的水平程度。做到了這些就能防止卷簾門(mén)的包箱下垂，從而做到既美觀(guān)又實(shí)用。

When installing the rolling shutter door box, select the appropriate height at the contact point between the iron shelf and the wall to adjust the level of the box. After doing this, the bag box of the rolling shutter door can be prevented from sagging, so as to be beautiful and practical.
