卷帘门门体采用优良不锈钢等材料制作，采用平行四边形原理交接，伸缩灵活。济南卷帘门为伸缩棚格型，具有启闭平稳、透视门体，开启后占用空间小等特点。下面来讲讲注意事项！

The rolling shutter door body is made of excellent stainless steel and other materials. It is connected by the parallelogram principle, with flexible expansion. Jinan roller shutter door is of telescopic lattice type, which is characterized by stable opening and closing, perspective door body, and small space occupation after opening. Now let's talk about the precautions!

1.通过设置智能红外线防爬装置，遇人爬门时，系统会马上报警，从而保障门内的。

1. By setting an intelligent infrared anti climbing device, when someone climbs the door, the system will give an alarm immediately to ensure the safety inside 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 profiles: the strength of high hardness zinc aluminum alloy profiles can be greatly enhanced by adding different geometric ribs. After special electrophoresis treatment, the surface has unlimited luster, is not easy to stick dust, is not corroded by polluted gases, and will never rust, and has a long shelf life.

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: the main plastic parts of the door body (such as the connection between pipes, plastic parts, door moving parts, etc.) are made of high-quality engineering plastics (such as PC, PA), which have high toughness, impact resistance, torsion resistance, abrasion resistance, frost resistance, sun resistance, aging resistance, long service life, and are free from wind, snow, lightning, sunshine 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。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）采用卷帘门标准尺寸320mm（参照国外技术），保证交叉管固，并大大减少运行噪音。

4. Intelligent infrared probe anti-collision device: when the door body encounters people or foreign objects 30-50cm in the closing process, it can automatically return to operate, thus ensuring the safety of vehicles and pedestrians. Standard structure: The inner space of the gate truss (i.e. the distance between the two adjacent curved main pipes at the front and back, excluding the main pipe size) adopts a roller shutter door with a standard size of 320mm (referring to foreign technology) to ensure the solid cross pipes and greatly reduce operating noise.

5.独特工艺制作门体主框架型材由塑料件连接而成，连接位的螺丝固定采用隐型设计，提高门体的外观性，型材与塑料件的连接则采用冲、压、钻等工艺，使门体结构牢固，绝无焊点。交叉连接设计：交叉管采用特殊工艺冲制而成，并配用超级PA耐磨套，与圆管紧密结合不仅使门排结构更加牢固，而且保证运行更加平滑。

5. The main frame profile of the door body is made of plastic parts by a unique process. The screw fixing of the connection position adopts a hidden design to improve the appearance of the door body. The connection between the profile and the plastic parts adopts punching, pressing, drilling and other processes to make the door body structure firm without welding spots. Cross connection design: the cross tube is made by special process and equipped with super PA wear-resistant sleeve. The close combination with the round tube not only makes the gate truss structure more firm, but also ensures smooth operation.
