The invention discloses a hinge structure of a steel security door. The hinge structure comprises a door frame, a door leaf and a hinge. The hinged part of the door leaf with the door frame is provided with an anti-prizing projection, a protruding step surface is formed, and the door frame correspondingly forms a recess step surface. The hinge is provided with a pivot and two hinge pieces, the hinge pieces are fixed with the door frame and the door leaf respectively, the combined parts of the surfaces of the door frame and the door leaf with the hinge are provided with an elongated through hole respectively, the hinge pieces penetrate the elongated through holes respectively and extend into the door frame and the door leaf. The hinge pieces are substantially planar and provided with screw holes, and fastening bolts penetrate the surfaces of the door frame and the door leaf respectively and are connected with the hinge pieces in a threaded manner. The hinge pieces are provided with screw holes, and the hinge pieces are used as bases of the bolts. Thus, gaskets in the prior art and welding are omitted, and material quality and thickness of the hinge pieces are generally excellent than other parts, so that the hinge pieces as the bases of the bolts can guarantee firmness of mounting better.
