"Electric roller shutter" is a kind of electric roller shutter mechanism with tubular motor as power. Its operation only needs to move the power switch. It is easy to operate, quiet and stable. 

It is an upgraded product of manual roller shutter. The motor is directly installed in the aluminum alloy rolling tube, which not only reduces the volume and force transmission link of the curtain box, but also avoids the external influence on the motor and increases the reliability of the mechanism. 

Coil tube is made of high quality aluminum alloy with high strength and is not easy to deform; 

its surface is anodized to prevent aging and corrosion. High strength alloy steel is selected as the mounting bracket, with high bending and shear strength, to ensure the safety and reliability of mechanism installation and use.
