1, intelligent infrared anti creeping device: when people climb the door, the system will immediately alarm, so as to ensure the safety of the door.

2、特种型材：在高硬度锌铝合金型材上加上不同几何形状筋骨能大大增强其强度，表面经特殊电泳处理，光泽无限，不易粘尘，不被污染气体腐蚀，决不生锈，保新期长。

2, special profile: adding different shapes and bones on high hardness zinc aluminum alloy section can greatly enhance its strength. The surface is treated by special electrophoresis, the luster is infinite, it is not easy to stick to dust, it will not be corroded by polluting gas, and it will never rust. It will keep the new period long.

3、工程塑料：门体主要塑料件（如管材与管材间的连接，塑料件，门体活动部件等等）采用高质量工程塑料（如PC、PA），韧性高，耐冲击,抗扭曲，耐磨，耐冻，耐晒，不易老化，使用寿命长，免受风雪雷电、日晒雨淋之苦。

3, engineering plastics: main body parts (such as plastic door connecting pipes and pipes between the plastic parts, door body moving parts etc.) with high quality engineering plastics (PC, PA), high toughness, impact resistance, anti distortion, abrasion resistance, frost resistance, light fastness, not easy to aging, long service life. From the snow, lightning, sun and rain.

4、智能红外线探头防碰撞装置：门体在关闭过程中遇人或异物30-50cm可自动返回运行，从而保障车辆及行人 的安全。 标准结构:门排内空（即前后相临两大弯主管之间的距离，不含主管尺寸）采用伸缩门标准尺寸320mm（参照国外技术），保证交叉管最固，并大大减少运行噪音。

4, intelligent infrared detector anti-collision device: door in the closing process encountered human or foreign matter 30-50cm can automatically return to operation, so as to protect the safety of vehicles and pedestrians. Standard structure: door row space (i.e. between two adjacent large head before and after the distance, without charge size) with retractable door standard size 320mm (according to foreign technology, to ensure the most solid cross tube), and greatly reduce the operation noise.
