The useful model is related to an armoured door, which is used in the construction of industrial, public, and residential buildings for securing reliable protection against burglaries and thefts. It is stable, functional, with increased strength and reliability, easy for installation, and meets the modern requirements for estheticism. The door consists of casing (1) with hinges (2), and a wing (3), executed with bearing frame (4) and panel (5), built from external (6) and internal (7) face panels, with built-in filling (8) of insulation material, and a protective metal sheet (9). The external(6) and internal (7) face panels are connected immovably along the peripheries by means of a bearing rectangular frame (4), formed from vertical (10) and horizontal (11) closing profiles, while in the rectangular frame (4) are mounted the stabilizing crosswise elements (16). In the panel (5) of the door is incorporated a lock (12), which is protected by the safety box (25), and the lock (12) is with locking mechanism having upper (13) and lower (14) locking bars. The vertical (10) and horizontal (11) bearing profiles are hollow rectangular tubular elements with external bent (15), to which is fastened the external face panel (6), while the opposite side of the tubular element is fastened to the internal face panel (7). The casing (1) is executed from a hollow bearing profile (17) with external bent (18), and to the bearing profile (17) are immovably fastened external (19) and internal (20) skirtings. The inner skirting (20) consists of boxing (21), in which is formed a chute (27), in which is movably mounted a compensating element (22). Between the casing (1), and the wing (3) of the door are mounted an external seal (23), and an internal seal (24). On the side of the hinges (2)are immovably mounted protruding outwards protection barbs (26), which when the door is closed enter the openings formed in the vertical profile (10) of the bearing rectangular frame (4) of wing (3).
