Experts visit industry and measure the size of space
then COAD produces the door.
That is why COAD rolling up door is fitted in the space without any gap.
This industry chooses COAD-3.
It is zipper type so the sheet completely blocks the outside objects.
The sheet of rolling up door is chosen by customers' preference.
The color and type of sheet is diverse for customers.

In normal, orange is in food and packaging industry,
blue in manufacturer of components
and gray in pharmaceuticals and laboratory.
The transparency prevents the unexpected collision
between employee and door.
COAD develops controller only for rolling up door.
The controller manages direction and speed of motor.

such as air-curtain, air-shower, conveyor, and etc,
then COAD controller activates those devices with rolling up door.
For safety, COAD puts double photo beam sensors on the rail.
It prevents the operation as person enters.
