1. Product Definition & Key Features

A motorized roller shutter door is an automated door system with a vertically rolling curtain, widely used in commercial, industrial, and residential settings. Core features include:

• Rapid Operation: Rolling speed 0.3-1.2 m/s, supporting ≥500 daily cycles.

• Compact Design: Curtain rolls into a compact overhead drum, ideal for space-constrained installations.

• Security: Curtain materials (aluminum, steel, or PVC) with anti-pry locks meet basic anti-theft standards.

• Cost-Effective: 30%-50% lower total cost compared to other rapid doors, suitable for small-to-medium projects.

2. Structural Components

1. Curtain System

2. Aluminum: 0.5-2mm thickness, lightweight for retail shops.

3. Galvanized Steel: 0.5-2.5mm thickness, powder-coated for impact resistance.

4. Materials:

5. Roller Drum: Seamless steel or aluminum tube (80-150mm diameter).

6. Drive System

7. Motor: 220V/380V tubular motor/chain motor , remote/manual switching.

8. Transmission: Gearbox + chain/belt drive (noise ≤60dB).

9. Control System

10. Standard: Wireless remote, wall switch.

11. Optional: Infrared sensors, keypad.

12. Safety Features

13. Bottom Rubber Seal: Anti-pinch buffer (collision force ≤50N).

14. Anti-Drop Device: Locks curtain upon drum failure.

3. Technical Specifications

4. Core Advantages

1. Flexible Configuration: Single/directional opening, side/central motor mounting.

2. Durability: Aluminum/steel curtains last ≥10 years (100 daily cycles).

3. Low Maintenance: Modular design allows curtain/guide replacement (annual upkeep <3% of cost).

4. Basic Sealing: Weighted bottom bar + side rubber seals (dustproof IP3X).

5. Typical Applications

• Retail Stores: Convenience stores, bank branches (security + access control).

• Industrial Warehouses: Small warehouse entrances (basic isolation/theft prevention).

• Underground Parking: Private lots replacing manual shutters.

• Temporary Partitions: Exhibitions/construction sites for rapid zoning.

6. Selection Guidelines

1. Standard Configurations:

2. Light Duty (openings ≤3m×3m): Aluminum curtain + 0.4kW tubular motor.

Heavy Duty (openings >3m×3m): Steel curtain + 1.5kW gear motor.

3. Environmental Adaptation:

4. High humidity: Galvanized steel curtain + stainless steel guides.

Sub-zero environments:  (-30°C rated).

5. Security Upgrades:

6. Enhanced anti-theft: Mechanical locks (EN 1627 RC2 compliant).

7. Installation & Maintenance

• Installation Requirements:

• Leveling tolerance ≤2mm/m; drum alignment ≤1.5mm.

• Power: 220V ±10%, grounding resistance ≤4Ω.

• Routine Maintenance:

• Monthly: Clean guides, inspect curtain integrity.

• Biannually: Lubricate chains/belts, test anti-drop function.

• Troubleshooting:

• Curtain Jamming: Check guide obstructions or drum misalignment.

• Remote Failure: Replace batteries or eliminate signal interference.
