The roller shutter door body is made of high-quality stainless steel and other materials, using a parallelogram principle for joints, allowing for flexible extension and retraction. The drive unit uses a special motor with worm gear reduction and a manual clutch, allowing for manual opening and closing during power outages. The roller shutter door is a telescopic lattice type, featuring smooth opening and closing, visibility of the door body, and minimal space occupation when open.
1. Equipped with an intelligent infrared anti-climb device, the system will immediately sound an alarm if someone attempts to climb the door, ensuring safety inside.
2. Special Profiles: High-hardness zinc-aluminum alloy profiles with added geometric ribs greatly enhance their strength. The surface undergoes a special electrophoretic treatment, resulting in a lustrous finish, resistance to dust accumulation, and protection against corrosion from polluted gases, ensuring rust resistance and a long-lasting new appearance.
3. Engineering Plastics: The main plastic components of the door (such as pipe connections, plastic parts, moving parts, etc.) are made of high-quality engineering plastics (such as PC and PA), which are highly tough, impact-resistant, torsion-resistant, wear-resistant, freeze-resistant, sun-resistant, not prone to aging, and have a long service life, protecting them from wind, snow, lightning, sun, and rain.
4. Intelligent Infrared Sensor Anti-Collision Device: The door automatically reverses direction when it encounters a person or object within 30-50cm during closing, ensuring the safety of vehicles and pedestrians. Standard Structure: The internal clearance of the door frame (i.e., the distance between two adjacent main curved pipes, excluding the main pipe dimensions) adopts the standard roller shutter door size of 320mm (referencing international technology), ensuring the strongest cross-pipe structure and significantly reducing operating noise.
5. Unique Manufacturing Process: The main frame profiles of the door are connected by plastic parts. The screws at the connection points are concealed, improving the door's appearance. The connection between the profiles and plastic parts uses punching, pressing, and drilling processes, making the door structure robust and eliminating weld points. Cross-connection design: The cross tubes are stamped using a special process and equipped with super PA wear-resistant sleeves. Their tight connection with the round tubes not only makes the door structure more robust but also ensures smoother operation.
6. Features of roller shutter doors: Beautifies the environment, improves the appearance of businesses, and enhances corporate image; helps create a civilized enterprise, civilized factory, and civilized city atmosphere; improves security, immediately triggering an alarm even in the event of vandalism or intrusion at night. Roller shutter doors are mainly used in residential communities, government agencies, schools, enterprises, and institutions.
