铝合金电动伸缩门主体结构与不锈钢相似，也是利用平行四边形的运动原理，采用标准的铝合金型材直接用模具压制成型，然后通过镀锌管以及交叉连杆连接而成。与传统的不锈钢电动门相比，材质更优，造型更美观，更加耐腐蚀。铝合金伸缩门,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。最新交叉连接设计：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。
The main structure of the aluminum alloy electric expansion door is similar to that of the stainless steel. It is also made by using the principle of parallelogram movement, using the standard aluminum alloy profiles directly pressed by the mold, and then connected by the galvanized pipe and cross connecting rod. Compared with the traditional stainless steel electric door, the material is better, the shape is more beautiful and more corrosion-resistant. Aluminum alloy expansion door. The main frame profile of the door body is made of plastic parts by a unique process. The screws at the connection position are fixed in a concealed design to improve the appearance of the door body. The connection between the profile and the plastic parts is made of punching, pressing, drilling and other processes to make the structure of the door body firm without any welding points. The latest cross connection design: the cross pipe is made by special process and equipped with super PA wear-resistant sleeve. The close combination with the round pipe not only makes the door truss structure stronger, but also ensures smooth operation.

形象;有助于营造文明企业、文明工厂、文明城市气氛;提高安全性、即使深夜遇有破坏或翻越，立刻报警。伸缩门主要用于生活小区，机关学校，企业事业单位、各个工厂，等。
The characteristics of the expansion door beautify the environment, improve the appearance of the enterprise and enhance the image of the enterprise; help to create a civilized enterprise, civilized factory and civilized city atmosphere; improve the safety, even if there is damage or crossing in the late night, immediately call the police. The expansion door is mainly used in living quarters, government schools, enterprises and institutions, various factories, etc.
