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.
