The fire double door comprises two door leafs hinged on a common door frame.

The door leafs are made of 100 mm thick sandwich panels with a minimum mineral core density of 170 kg/m3 and fire reaction rating A1. Embedded within the panels are reinforcing steel bars (a solution protected by European Patent no. W 02/079600A1) which bind the leaf frame flat bars to which the hinges are attached on one side and on the other side of which the lock assembly (on the active leaf) or the vertical locking bolt (on the passive leaf) is installed. The outside surfaces of the panels are lined with adhesively bonded sheet metal cladding, 0.5 - 0.7 mm.

Each door leaf is suspended on a minimum of three hinges provided with 3D alignment adjustment

The door frame is made of flat bars lined with steel sheet profiles with inward-fastened fireproof and rubber seals. The door frame can be ordered as a corner or a butted frame.

Either door leaf can be provided with hinged steel man door with the fire resistance of the main door.

The man door is available with or without a threshold.

The standard man door version is provided with a lever tumbler lock, double-sided door handle hardware and spring-return hinges; they can also be provided with panic exit devices (with locks, levers, or pushbars), and a sliding rail door closer.

The standard colour selection includes RAL 7035, 9002, 9010 and 7016
