Lotte needs doors that hold under fire, pass any closing test and get signed off by the consultant. We install them, maintain them, replace them — approved, tested, documented.
Unlike a residential door, a fire door must be automatically latching and must carry an declaration of conformity. The frame is part of the rated assembly — swap any component without re-certification and the rating is gone. That's why we never improvise on hardware.
