Storage Type

Product Features

With the minimal interference of ceiling and speed door motor,
automatic door three times faster than conventional doors

  • With its speed door motor, the door can be opened and closed 3 times faster than conventional overhead door.
  • With the minimal storage space of the panel, this door has minimal interfere with ceiling light, pipe, crane, and others.
  • Based on chain-driving type rather than wire-driving type, this door reduces customer service expenses for
    wire separation and disconnection.

icon Lift

Standard Lift

Type of building | Buildings for standard industry

Advantage | the standard lift track set designed optimally
for general buildings is the most general method
based on the spring package right above door.


High Lift

Type of building | High ceiling & high lift tract set
spring package is installed high over door.

Advantage | A high-rise vehicle is able to pass through
an opened door without any obstacle of horizontal track.
This type of track is applied to the case where there is
a large space over door, for instance, the case where
a high-rise vehicle needs to pass through.


Low Lift

– Implementation of maximum sunlight height with the minimum head room
– Equal to standard lift, but spring package at the end of horizontal track
– The space between door opening and ceiling does not need more than 265mm.


Vertical Lift

Type of building | a place with very high ceiling and high work space

Advantages| A high-rise vehicle is able to pass through an
opened door without any obstacle of vertical track.
If there is enough space between sunlight height and root,
this type of door is able to be opened vertically.
