首先，第一种是没有架子支撑的卷帘机，它的价位在三千左右，它的优点是体型小，有的季节不需要卷帘机的时候可以收起来，收纳方便。别看它体型小，它的马力很足，能卷六十到七十米的长度。缺点就是卷帘的时候需要人工看着调整方向，以免走斜损坏草帘。
First of all, the first one is the roller shutter without shelf support. Its price is about 3000 yuan. Its advantage is that it is small in size. It can be put away when there is no need for the roller shutter in some seasons, which is convenient for storage. Despite its small size, it has enough horsepower to roll 60 to 70 meters. The disadvantage is that when rolling up the curtain, you need to look at the adjustment direction manually, so as not to damage the straw curtain due to the deviation.
其次，第二种是有架子支撑的卷帘机，也称撑杆式卷帘机，大小不同的价位也不同。它的优点是不需要人工看守，价格比上一类卷帘机便宜，卷帘效果不错易于管理，适应范围距离长马力也很足。缺点就是容易被大风刮倒稳固性一般，而且要是棚面不整这种卷帘机容易跑偏，最重要的是高压电线附近不能使用。
Secondly, the second kind is a frame supported roller shutter, also known as strut roller shutter, with different sizes and prices. Its advantage is that it does not need to be guarded manually, the price is cheaper than the previous type of rolling machine, the rolling effect is good and easy to manage, and the adaptation range is long and horsepower is sufficient. The disadvantage is that it is easy to be blown down by the strong wind, and if the shed surface is not complete, this kind of rolling machine is easy to deviate, and the most important thing is that it cannot be used near the high-voltage wire.
