电动伸缩门是一种由自由移动控制器来控制门洞大小的门，也就方便在拦截和放行行人或车辆的时候控制门洞宽度。电动伸缩门主要由门体、驱动电机、滑轨和控制系统组成。门体采用不锈钢或铝合金型材，采用平行四边形原理铰接，伸缩灵活，行程大。驱动由专用电机驱动，蜗轮减速，并配有自动离合器或手动离合器。自动离合器可在停电时自动打开和关闭，手动离合器可在停电时手动打开和关闭。控制系统可根据需要配备控制板、按钮开关、无线遥控装置。
Electric telescopic door is a type of door that is controlled by a free movement controller to control the size of the door opening, making it convenient to control the width of the door opening when intercepting and releasing pedestrians or vehicles. The electric telescopic door mainly consists of the door body, driving motor, sliding rail, and control system. The door body is made of stainless steel or aluminum alloy profiles, articulated using the parallelogram principle, with flexible expansion and large stroke. The drive is driven by a dedicated motor, with worm gear reduction and equipped with an automatic or manual clutch. The automatic clutch can be automatically opened and closed during a power outage, while the manual clutch can be manually opened and closed during a power outage. The control system can be equipped with control boards, button switches, and wireless remote control devices as needed.
可用于制作电动伸缩门的材质有很多，比如标题中所提到的铝合金和不锈钢，以及还有镀锌钢等其他材料。不同种材料的伸缩门产品当然是有区别的，今天我们主要说说铝合金和不锈钢的区别。
There are many materials that can be used to make electric telescopic doors, such as aluminum alloy and stainless steel mentioned in the title, as well as other materials such as galvanized steel. Of course, there are differences in the products of expansion doors made of different materials. Today, we will mainly talk about the differences between aluminum alloy and stainless steel.
铝合金伸缩门与不锈钢伸缩门的区别在于：
The difference between aluminum alloy expansion doors and stainless steel expansion doors is:
1、价格：由于市面上的不锈钢材料比铝合金贵，所以制作不锈钢伸缩门的成本较高，不锈钢伸缩门的价格高于铝合金伸缩门。
1. Price: Due to the fact that stainless steel materials on the market are more expensive than aluminum alloys, the cost of making stainless steel expansion doors is higher. The price of stainless steel expansion doors is higher than that of aluminum alloy expansion doors.
2、外观：铝合金的造型款式更加多样，可型线  流水槽模具 景观石 检查井钢模具 保定通风管道 隔离墩模具 保定保洁公司塑性高，而不锈钢的造型单一，基本为方形。
2. Appearance: Aluminum alloy has a more diverse style and high plasticity, while stainless steel has a single shape and is basically square.
3、耐用性：由于不锈钢的性能优于铝合金，所以不锈钢伸缩门的平均使用寿命更长，一般在十年以上。而铝合金伸缩门的使用寿命稍短一些。
3. Durability: Due to the superior performance of stainless steel over aluminum alloy, the average service life of stainless steel expansion doors is longer, usually over ten years. The service life of aluminum alloy expansion doors is slightly shorter.
