Functions and characteristics of aluminum alloy roller shutter door

The roller shutter door body is made of high-quality aluminum alloy and other materials, and the parallelogram principle is adopted for connection, with flexible expansion and contraction. The drive is driven by a special motor, and the worm and worm gear are decelerated. It is equipped with a manual clutch, which can be opened and closed manually in case of power failure. The rolling shutter door is of the telescopic shed type, which has the characteristics of stable opening and closing, perspective of the door body, and small space occupied after opening.

1. By setting an intelligent infrared anti climbing device, when someone climbs the door, the system will give an alarm immediately, so as to ensure the safety inside the door.

2. Special profile: the strength of high hardness zinc aluminum alloy profile can be greatly enhanced by adding different geometric shapes of ribs and bones. The surface is treated by special electrophoresis, with infinite luster, not easy to stick to dust, not corroded by polluted gas, never rusting, and long warranty period.

3. Engineering Plastics: the main plastic parts of the door body (such as the connection between pipes, plastic parts, moving parts of the door body, etc.) are made of high-quality engineering plastics (such as PC and PA), which are high in toughness, impact resistance, distortion resistance, wear resistance, frost resistance, sun resistance, not easy to age, long in service life, and free from wind, snow, lightning, sun and rain.

4. Intelligent infrared probe anti-collision device: when the door is closed, it can automatically return to operation when encountering 30-50cm people or foreign objects, so as to ensure the safety of vehicles and pedestrians. Standard structure: the standard size of the roller shutter door is 320mm (refer to foreign technology) for the inner space of the door row (i.e. the distance between the two adjacent main pipes in front and back, excluding the size of the main pipe), to ensure the most solid cross pipe and greatly reduce the operating noise.

5. The main frame profile of the door body made by a unique process is connected by plastic parts. The screws at the connection position are fixed by concealed design to improve the appearance of the door body. The connection between the profile and the plastic parts is made by punching, pressing, drilling and other processes, so that the door body structure is firm and there are no welding spots. Cross connection design: the cross pipe is punched by special process and equipped with super PA wear-resistant sleeve. It is closely combined with the round pipe, which not only makes the door structure more firm, but also ensures smooth operation.

6. The characteristics of roller shutter doors beautify the environment, improve the appearance of enterprises and enhance the image of enterprises; It helps to create an atmosphere of civilized enterprises, factories and cities; Improve safety, even if there is damage or climbing at night, immediately report to the police. Roller shutter doors are mainly used in living quarters, government schools, enterprises and institutions
