目前市面上的电动伸缩门大致可分为以下几类：烤漆铁电动伸缩门、钢制电动伸缩门、不锈钢电动伸缩门、铝合金电动伸缩门。
At present, electric expansion doors on the market can be roughly divided into the following categories: painted iron electric expansion doors, steel electric expansion doors, stainless steel electric expansion doors, and aluminum alloy electric expansion doors.
不同材料制成的电动伸缩门的特点和使用寿命是不同的。例如，喷漆铁伸缩门使用一段时间后油漆会脱落，不锈钢伸缩门在雨水酸碱度高的沿海地区容易腐蚀生锈，铝合金电动伸缩门在强风频繁的地区容易被风吹倒或偏离。
The characteristics and service life of electric telescopic doors made of different materials vary. For example, painted iron expansion doors may peel off paint after a period of use, stainless steel expansion doors are prone to corrosion and rust in coastal areas with high acidity and alkalinity in rainwater, and aluminum alloy electric expansion doors are prone to being blown down or deviated by strong winds in areas with frequent winds.
消费者在选择材料时，首先要了解使用电动伸缩门的地方对产品选择的限制。在企业大门、机关、机关等长期使用的场所，建议使用精制加厚型材。普通型材可用于建筑工地和临时租用工地。在沿海工业发达、酸雨较多的城市，建议购买铝合金电动伸缩门。在一些台风多发地区，推荐使用不锈钢电动伸缩门。
When choosing materials, consumers should first understand the limitations on product selection where electric retractable doors are used. It is recommended to use refined and thickened profiles in places such as enterprise gates, offices, and offices that have been used for a long time. Ordinary profiles can be used for construction sites and temporary rental sites. In cities with developed coastal industries and frequent acid rain, it is recommended to purchase aluminum alloy electric telescopic doors. In some typhoon prone areas, it is recommended to use stainless steel electric telescopic doors.
尺寸选择
Size selection
由于不同的门宽度不同，在选购伸缩门时，首先要利用好自己的门尺寸。不同的伸缩门收缩后的尺寸不同，所以伸缩门长度的主流计算方法是按伸缩后的总长度计算。
Due to the different widths of doors, when choosing a retractable door, it is important to first make good use of your own door size. The main calculation method for the length of retractable doors is based on the total length after expansion, as different retractable doors have different sizes after contraction.
为了保证电动伸缩门的完全关闭，一般厂家都会使电动伸缩门比门的实际长度长一点。消费者在购买时，只要报出自己的闸门的真实宽度，工程师就可以根据你的闸门计算出电动闸门的长度。
In order to ensure the complete closure of the electric retractable door, manufacturers generally make the electric retractable door slightly longer than the actual length of the door. When consumers make a purchase, as long as they report the true width of their gate, engineers can calculate the length of the electric gate based on your gate.
其他规格参数的选择
Selection of other specifications and parameters
比如电机品牌、电机功率、芯材、控制方式等。
For example, motor brand, motor power, core material, control method, etc.
