The invention discloses an ultralow-energy-consumption steel composite anti-theft safety door. The ultralow-energy-consumption steel composite anti-theft safety door comprises a door frame (1) and door leaves (3) connected with the door frame (1) through hinges (2). The door leaves (3) are provided with a lockset (4), the keys are that the door frame (1) is provided with at least one structure forblocking heat conduction, each door leaf (3) is provided with at least one structure for blocking heat conduction, and at least two air blocking structures for blocking airflow are arranged between the door frame (1) and each door leaf (3). According to the ultralow-energy-consumption steel composite anti-theft safety door, a plurality of sealing parts are adopted between the door frame and the door leaves as well as between every two door leaves, the integral air tightness of the anti-theft safety door is improved, and therefore the anti-theft safety door has good anti-theft safety performance and excellent heat insulation and sound insulation performance.
