门排间距
Gate row spacing
所谓门排间距是指电动伸缩门表面材料之间的距离。很多生产企业为了降低产品的生产成本，自行扩大电动伸缩门的门排间距，大大超过行业标准。电动伸缩门的价格是以米计算的，所以我们在购买电动伸缩门产品时要注意这一点。不要只关注电动伸缩门的总长度，也不要忽视门排间距。
The so-called door row spacing refers to the distance between the surface materials of electric telescopic doors. Many production enterprises, in order to reduce the production cost of their products, have expanded the spacing between the door rows of electric retractable doors, greatly exceeding industry standards. The price of electric telescopic doors is calculated in meters, so we should pay attention to this when purchasing electric telescopic door products. Don't just focus on the total length of electric retractable doors, nor ignore the spacing between door rows.
4、厂家的售后服务
4. Manufacturer's after-sales service
消费者在订购电动伸缩门时，应明确询问哪些内容、哪些项目收费、哪些项目不收费等保证。因此，在任何产品中，售后服务都显得尤为重要。特别是大型产品的售后服务非常重要。因为这关系到消费者收到货后是否满意，因为退货会给对方带来麻烦。
Consumers should clearly inquire about what content, which items are charged, and which items are not charged when ordering electric retractable doors. Therefore, in any product, after-sales service is particularly important. Especially for large-scale products, after-sales service is very important. Because this is related to whether consumers are satisfied with receiving the goods, as returning the goods can cause trouble for the other party.
