其实伸缩门主要是看看是哪一种的伸缩门。现在许多的人对物质追求越来越高，因此出现了电动伸缩门，无人监管，红外线的智能，并且电动伸缩门的安保比较完善，配置红外防撞和防攀爬系统：当路人及车辆经过正在运行里的伸缩门时，门会自动暂停；当人及车辆离开后，门自动恢复运作。当布防情况下，如有人翻过时，装于门柱里的警灯、警报会马上传出光控报警，声音响度超过100声贝。
Actually, the main purpose of a telescopic door is to see which type of telescopic door it is. Nowadays, many people's pursuit of material possessions is becoming increasingly high, leading to the emergence of electric retractable doors, which are unmanned and infrared intelligent. The security of electric retractable doors is relatively complete, equipped with infrared anti-collision and anti climbing systems: when pedestrians and vehicles pass through the running retractable doors, the doors will automatically pause; When people and vehicles leave, the door automatically resumes operation. When deployed, if someone passes over, the alarm lights and alarms installed in the door pillar will immediately emit a light controlled alarm, with a sound level exceeding 100 decibels.

组合型的伸缩门便会用在一些停车场或是娱乐场所之类的，因为这一类的耐撞力较为薄弱，因此如今一体式的伸缩门逐渐的替代组合型的伸缩门了，一体式伸缩门材料全部选用强度较强的低碳钢、构造密切、强度高，好用，绿色，美观都具有，很受大家欢迎。
Combination type expansion doors are commonly used in parking lots or entertainment venues, as their impact resistance is relatively weak. Therefore, nowadays, integrated expansion doors are gradually replacing combination type expansion doors. All materials for integrated expansion doors are made of high-strength low-carbon steel, closely constructed, high-strength, user-friendly, green, and aesthetically pleasing, which are very popular among people.
