How to improve the manufacturing process of fire doors

1. When using fireproof hinges, the hinges that can be separated and disassembled should be selected, so that when the fire doors are installed, they can be fixed separately and then directly inserted into the door frame.

2. When fixing the hinges and door closers, the method of fixing with wood screws should be changed. The holes for fixing hinges are reserved on the door frame and the door leaf, and then the relevant screws and nuts are provided, so that when the installation site is reached, Standardized work can be carried out according to the reserved holes. The screws and nuts on the door leaf should preferably be equipped with corresponding heat-insulating decorations.

3. To determine the use of double-fan and multi-fan fire doors, the signal feedback line should be reserved during the construction process. The installation unit of the fire door should contact the construction unit and the construction unit of the fire protection project early, and reserve the line and control module. In order to facilitate the installation and commissioning of fire doors.
