Doors are essential components in any building structure, not only serving as points of access and exit but also contributing to security, privacy, ventilation, and aesthetics. In building services and maintenance, doors are classified based on various factors, and one of the primary classifications is based on their working operations.

On the basis of working operations, doors are broadly classified into the following types: 1. Swing Doors Swing doors are the most commonly used type of doors. They rotate on hinges fixed to the side of the door frame. These doors can be single or double shuttered and generally swing in one direction—either inward or outward. In some cases, especially in commercial spaces, double-action hinges are used to allow the door to swing in both directions. Swing doors require clear floor space for the arc of movement, which must be considered during space planning. Maintenance includes lubrication of hinges, tightening of screws, and regular alignment checks. Swing doors are suitable for rooms, bathrooms, and public buildings. 2.
