Aluminum alloy rolling shutter door

This kind of door is the most common and conditional one made by aluminum alloy. As we all know, aluminum are weaker than those of other common metals but once it mixed with other metals such as magnesium, silicon or copper it will turn into a tough guy who are strong enough that even shape weapon can’t hurt it. The advantage of aluminum alloy are both in the appearance as it shines as silver in the sunshine and its environmental friendly feature. However, the deadly shortage of this door is too loud noise when opening up and closing down.

Color steel rolling shutter door

There are many kinds of color steel plate color, and you can choose the door plate according to different requirements. They feature in the super light weight. Besides that they are strong enough to work as bearing plate of ceiling enclosure structure and easy to install, narrowing nearly 40 percent time of the construction period. However, this material needs high maintenance costs since the outside spray lacquer will falling out as the times by which may influence the appearance significantly. Further more, it has a poor thermal and sound insulation in general. If you want a better thermal and sound insulation, thicker plates would help but it means increasing costs.

Grid rolling shutter door

Grid rolling shutter door is not only breathable and transparent, but also has good anti-theft effect. It is a modern rolling shutter door.

Stainless steel rolling shutter door

The surface of the stainless steel rolling shutter door is very shiny, not only wear-resistant but also more anti-scratch, and it is also very easy to clean up.

Matters need attention about rolling up doors

The continuous rolling time of the rolling gate motor shall not exceed 5-10 minutes, because the motor is easy to heat up if the continuous running time of the motor exceeds the specified time. If the temperature of the motor exceeds 120℃, the internal heat protector of the machine will automatically cut off, and the protection device can automatically reset until the temperature drops to 70℃ (about 8 minutes).

When opening or closing the electric rolling gate, the operator shall not leave the site. It is strictly prohibited to stand or walk under the gate when the motor is debugging or running to ensure safety. When opening and closing the rolling gate, pay attention to keep the effective distance between the rolling curtain and the ground and the curtain box, to prevent the phenomenon of the rolling curtain and track stuck and the rolling curtain involved in the curtain box, which is more than 10CM away from the ground and 20CM away from the curtain box.

Factors when choosing rolling up doors

We should choose more deft, strong and durable material, so that it could be withstand the outside force in any special conditions. Stainless steel would be the best choice which may provide you a door similar to bulletproof rolling shutter door.

Electrical machine of rolling up door is also an important part that we couldn’t neglect it. Please keep in mind that the power provided by the machine must be larger than the lifting needs  because the bearing capacity of the rolling shutter door motor will slowly reduce the actual lifting effect with the passage of time, so the material selection should exceed the actual lifting force of the curtain as far as possible.

We should pay attention to the structure of the electric curtain door and the smooth of movement.

Brand is also an integral factor. Many small processing plants in order to lower the cost, blindly choose poor quality material of accessories. So customers should consider the brand of the enterprise when buying rolling shutter doors.
