Sliding fire door (multiple wings)
Sliding fire doors can be installed when there is some space available to both sides of the door opening. The advantage of this type of door is that it can be made in large sizes. The door slats and the track box can be painted any colour from the RAL colour chart. A built-in pedestrian exit can be installed.
