Introduction of roller shutters

Classify

1. According to the open type, the shutter door can be divided into manual shutter and electric curtain.

 Manual rolling curtain: with the help of the torsion spring on the central axis of the rolling curtain balance force, to achieve the purpose of manually pulling the rolling curtain.

 Electric shutter: use a special motor to drive the central axis of the shutter to reach the shutter switch, and automatically stop when the rotation is reached to the upper and lower limits set by the motor.

2. According to the door piece material, the rolling shutter door can be divided into: aluminum alloy rolling shutter door, crystal rolling shutter door, stainless steel rolling shutter door, color steel plate rolling shutter door, PVC rolling shutter door, etc.

 Aluminum alloy rolling curtain door

Aluminum alloy shutter curtain different material and structure design, can effectively prevent high light and ultraviolet radiation, completely solve the sunlight of indoor greenhouse effect, suitable for all kinds of climate and weather change, the indoor environment has long-term protection effect, after the test shows that shutter doors of sunlight shielding rate can reach 100%, the occlusion rate of temperature can reach more than 95%.

 Color steel plate rolling curtain door

The door plate adopts color steel plate, aluminum alloy plate or composite plate, and choose the door plate of different thickness according to the width of the door hole. Lighting window and middle door (small door) can be added as needed.

 Crystal shutter door

Use polycarbonate (pc bulletproof glue) to manufacture engineering plastics. Crystal rolling shutter door has a certain waterproof, windproof effect, aluminum alloy connection reinforcement to strengthen the protective effect, and have frosted, transparent, colored and other specifications for selection.

 Stainless steel shutter door

With beautiful color, smooth, horizontal pattern relief design, rich in three-dimensional sense; door body surface after paint treatment, make the door plate more durable; a variety of installation methods, easy installation, construction speed to save time, if there is damage, single curtain replacement can be made to save cost.

PVC roll-up door

 Also known as the fast rolling shutter door, it is made of PV materials. It runs very fast, reaching 0.6 m / s. Can quickly isolation to ensure the workshop air quality dust-free grade, with heat preservation, cold, insect, wind, dustproof, sound insulation, fire prevention, odor prevention, lighting, and other functions, and widely used in food, chemical, textile, electronics, supermarket, freezing, logistics, warehousing, and other places, can meet high performance logistics and clean place, and save energy, high speed automatic closed, improve operation efficiency, create a better working environment 。

3. According to the installation form, the rolling shutter door can be divided into: wall, wall side (or inside the door, outside the door).

4. According to the opening direction, the rolling shutter door can be divided into two kinds: upper roll and side roll.

5. According to the use, the shutter door can be divided into: ordinary shutter door, wind shutter door, fire shutter door, fast rolling shutter door, electric Australian type (silent) shutter door.

6. According to the fire prevention rating, the rolling shutter doors are classified as follows:

According to GB14102 "General Technical Conditions for Steel Curtains", ordinary steel shutter is divided into: F1 grade, fire resistance time 1.50h; F2 grade, fire resistance time 2.0h. The composite steel shutter is divided into F3, fire resistance time 2.50h, F4, fire resistance time 3.00h.

According to the national standard "door and shutter fire test method" GB7633 fire test, including the requirements of backfire surface temperature rise in the judgment conditions, fire resistance limit 3.0h, called the super shutter, all in the fire resistance test does not take backfire surface temperature rise as the judgment conditions of the general ordinary shutter door 。

operational principle

The rolling shutter door is mainly composed of door body, driver and control system. The door body is made of high quality stainless steel and aluminum alloy special profile, using the principle of parallelogram hinge, flexible expansion and large stroke. The drive is driven by special motor, the worm wheel is decelerated, and has manual clutch, which can be opened and closed manually during power failure. The control system has control board, button switch, and wireless remote control device according to user needs. Can be equipped with a scrolling display screen.It can also be equipped with intelligent infrared dual-probe collision prevention device, where 20-30cm can automatically return to operation, so as to ensure the safety of vehicles and pedestrians.
