Sectional Door, Used For Factory And Hangar Doors, Easy To Operate, Wind-Resistant And Heat-Insulating
What is a sectional rolling shutter door?
Sectional roller shutter doors and roller shutter garage doors
Segmented steel doors are typically wide panels that can be customized by placing windows in some sections and steel in others. When retracted, these doors roll up and lie flat against the ceiling. The biggest advantage of this type of door is that it can be installed in almost any conditions
Insulated Sectional Doors
Industrial sectional doors, the door panel is made of double-layer sandwich hot-dip galvanized steel plate with surface polyurethane process, the core material is polyurethane insulation and thermal insulation layer, the thickness is 40mm. The end face of the door body is provided with a box-shaped edge banding, and the connecting hinge is mounted on the edge banding, so that the door body is embedded track. The top and bottom sealing strips and lateral sealing strips made of spherical vinyl resin along the width and height of the door are fixed on the bottom and the top to prevent wind, rain and penetration. The door body balance system is composed of torsion spring, reel, steel shaft and locking and fixed flange. The wheel is wrapped with steel, and the steel cable is connected to the steel cable breaking device at the bottom of the door. There- fore, it is also convenient to lift the door body without a motor in a balanced state
Product Details
| Part Name | Configuration | ||||||||
| Motor transmission system |
-Industrial door special motor: consisting of reduction gear, three-phase asynchronous motor, brake system and manual operation mechanism -Drive Mode: axle drive adopted, reducing secondary transmission mechanism, ensuring more stable and reliable operation -Manual chain mechanism: once motor or power failure, open/shut door easily via chain at bottom of motor, or rapidly via clutch mechanism of deceleration |
||||||||
| Control system |
- Digital signal processing chip, with full isolation circuit standard in industrial level, stable and reliable - Phase sequence protection: based on digital chip, with most advanced software calculation method, phase sequence protection is more stable and reliable - Overcurrent protection - HMl: highlight blue screen LCD adopted, displaying default, running and status code - Whole-course absolute value limit technique: Fourth generation industrial door limit technology, best in precision and stability in current market, achievable in control box - Vector frequency conversion technique: Constant torque output throughout, slow start and stop, free speed adjustment, one of best control method for Mechanical protection and life extension - Reserved ports: Interlock ports, remote control ports, infrared security protection ports, radar induction ports, etc. |

| Door plate |
- Double-layer hot dip galvanizing embossed anticorrosive coated steel plate. Polyurethane density 46kg/m3, thickness 40mm. Sealing strips adopted in each joint of door plate to ensure good sealing effect: Coated steel sheets for front and back door plate, Hiah corrosion resistance and weather resistance: single laver steel sheet thickness 0.4mm, filled with anti-flaming polyurethane material without Freon
|
||||||||
| Rail system | -Supporting and guiding door running, adopting high quality anticorrosive metal guide rail, rerail and rail bracket with thickness 2mm; Multiple ways of lifting according to actual civil structure on site: vertical lift standard hoist, high lintel lift, bottom lintel lift, etc. to optimize your building space | ||||||||
| Wind resistance coefficient | -Standard wind load 450N/m2 | ||||||||
| Torsion spring system | -Balance door weight with force of spring: Torsion spring system: inc. pivot, spring set, torsion spring (galvanized, at least 30,000 life cycles), rope wheel, coupling, etc. | ||||||||
| Tail-safe system |
- Torsion spring break-proof system: Guide spring easily break when tired after certain usage time, torsion spring break-proof system locks axle at once spring breaks, preventing accidents effectively (standard) - Wire rope anti-break device: installed at bottom of door plate, whatever wire rope sudden break happens when door runs up or down, device self-locks within 5cm to stop door from sliding, even accidents happen (standard) - Safety pressure switch: in process of decline, if presses on any object, door will instantly bounce up (standard) - Safety infrared ray counter switch: installed at bottom of door. If any obstacle under door, door will not close, or trigger in process of decline, it will immediately open to the highest position |
||||||||
| Sealing | Sealing strip at bottom, of ethylene-polypropylene adhesive material, inlaid installed, with function of anti-low temperature and ant-fracture, good sealing effect. Sealing assembled around to prevent rain, dust, sound. heat.etc |
