Many manufacturers do not know how to distinguish between good and bad products when choosing fast rolling shutter doors. In terms of surface configuration, the material of the door panel, motor, control box, control system, and other hardware conditions are the same. In this case, people often choose whichever is cheaper to use, but the real quality difference is often in the details.

比如说快速卷帘门的门板，目前市面上门板的厚度常见的规格有23mm、43mm、60mm、80mm、100mm，你有时候肯定会想为什么只有这几种厚度规格，其实这与门板加工设备有关，大家往往是选择市场常见的门板厚度的加工设备，批量化生产以此来大大降低门板生产成本，那么是不是指着全部的门板工艺都是一样的呢?答案肯定是不一样的。

For example, for the door panels of fast rolling shutter doors, the common thickness specifications for the door panels on the market currently include 23mm, 43mm, 60mm, 80mm, and 100mm. Sometimes you may wonder why there are only these thickness specifications. In fact, this is related to the door panel processing equipment. People often choose the commonly used door panel thickness processing equipment in the market for mass production to greatly reduce the production cost of the door panel, So does it mean that all the door panels have the same craftsmanship? The answer is definitely different.

涡轮硬质快速卷帘门的门板常见的工艺描述往往是，门板采用双层拉伸铝板一次复合制成，表面为细压制条纹经过阳极氧化处理，中间填充聚氨酯发泡剂。貌似大家都是一样的，但细看却不一样，比如说双面铝板拉伸工艺中，压制铝板的钢轴确定了门板的使用寿命。

The common process description for the door panel of turbo hard fast rolling shutter doors is often that the door panel is made of double-layer stretched aluminum plate in one composite, with a surface of fine pressed stripes and anodized treatment, and the middle is filled with polyurethane foaming agent. It seems that everyone is the same, but upon closer inspection, it is different. For example, in the double-sided aluminum sheet stretching process, the steel shaft used to press the aluminum sheet determines the service life of the door panel.

因为不同的加工设备，在铝板拉伸过程中的精密度不一样，当铝板受到挤压的时候，如果设备精密度达不到要求，会在铝板的表面造成肉眼无法看到的磨痕损伤，甚至门板表面会出现规律性的凸起，这样似的生产出来的门板整体不平整。我们都知道，涡轮硬质快速卷帘门以高速高频的特点，在工业生产制造中被广泛的应用，但如果门板表面有裂痕或者凸起，那么在门体运行中受到摩擦力的影响会严重影响产品质量。

Due to different processing equipment, the precision during the aluminum plate stretching process varies. When the aluminum plate is squeezed, if the precision of the equipment does not meet the requirements, it will cause invisible wear marks and damage on the surface of the aluminum plate, and even regular protrusions on the surface of the door plate, resulting in an overall unevenness of the produced door plate. We all know that turbine hard fast rolling shutter doors are widely used in industrial production and manufacturing due to their high-speed and high-frequency characteristics. However, if there are cracks or protrusions on the surface of the door panel, the friction force during the operation of the door body will seriously affect product quality.

这就是为什么有的快速卷帘门厂家的产品门板使用寿命长，而有的快速卷帘门的门板使用一段时间以后门板会破裂。所以在选择快速卷帘门的时候，不能仅仅看大的零配件，往往细节上决定的产品质量。

This is why some manufacturers of fast rolling shutter doors have long service life of their door panels, while others may rupture after a period of use. So when choosing a fast rolling shutter door, you can't just look at the large parts, as the details often determine the quality of the product.
