It is applied in the wide span and curve form fireproof of partitions in places like atriums, ground storages, etc.

Technical parameter
Smallest span size: W¡Ü45000mm, H¡Ü6000mm
When necessary, the two frames can move in opposite directions; The fire endureance¡Ý3.5h
It can move in curve forms or multi-direction types, with no need for guide rails on ground surface. The smallest bending radius R 800MM
The upper part of the rolling door nees the space of 200 mm-400mm
In a side direction steel fireproof rolling door, the curtain pieces are hung into the guide rails in the upper part. The door moves by wheel along the guide rail, to realize the start-up of the rolling brake, and can move in curve lines.
It adopts the rolling friction, with low resistance, and is applicable in wide spans.
It can be used in the atrium fireproof partition with no need for pillars. Becanse of the small space occupied by the upper part, it can be used in thr fireproof partitions at the places with height limitation such as uderground garages and so on.
