The purchase principles of Jinan roller shutter door are roughly as follows:

1.济南卷帘门导轨的地轨结构设计是否合理，直接对产品的性能和使用寿命产生很大的影响。作为普通消费者，在购买时，地柜的高度不要超过5mm，主要是考虑到儿童和老人的问题。同时，尽量选择便于清洁和卫生的泥土轨道。

1. Whether the ground rail structure design of Jinan roller shutter door guide rail is reasonable has a great impact on the performance and service life of the product. As an ordinary consumer, when buying, the height of the floor cabinet should not exceed 5mm, mainly considering the problems of children and the elderly. At the same time, try to choose dirt tracks that are easy to clean and sanitary.

2.济南卷门滑轮拨片由上下两套组成。质、量好的上滑轮结构复杂，内部有两个滑轮由轴承和铝件固定。济南卷帘门滑动模块配有自重装置，运行和滑动时不会有太大的振动和异响。

2. Jinan rolling gate pulley paddle is composed of upper and lower sets. The structure of the upper pulley with good quality and quantity is complex. There are two pulleys inside, which are fixed by bearings and aluminum parts. Jinan roller shutter door sliding module is equipped with self weight device, which will not have too much vibration and abnormal noise during operation and sliding.

3.选择市场上现有的卷帘门型材大致分为铝型材和铝镁合金两种。如果卷门整体质量比较高，可以选择铝镁合金卷门，坚固性有很大的优势。性能比较强，如果一般要求不高，可以选择铝型材，会比较低。

3. Select the existing rolling shutter door profiles in the market, which are roughly divided into aluminum profiles and aluminum magnesium alloy. If the overall quality of the rolling door is relatively high, aluminum magnesium alloy rolling door can be selected, which has great advantages in robustness. The performance is relatively strong. If the general requirements are not high, aluminum profiles can be selected, and the price will be relatively low.
