COMPOSITION & MANUFACTURE
A precision welded, strong metal frame holds a flush metal door through a concealed piano hinge. Actual construction varies dependant upon size and fire performance requirements. The door is held closed with a choice of locking systems and opens outwards towards the user. Doors are removable if damage occurs or during installation. Panels with simulated drywall beaded frames (BF) or deep plaster (DPF) are jointed/plastered over on site and finished to match the colour/texture of the adjacent surface. Retrofitted panels have a picture frame surround (PF) and are factory finished in powder coat white paint. A constant 3mm gap is maintained between the door and frame.
All Profab Riser Doors are made to order - largest individual door leaf size 1m x 3.1m (double and multiple leaf configurations available).
