The invention relates to a steel heat insulation fireproof door. Each door leaf of the fireproof door comprises a framework and a door leaf panel; each of the frameworks and the door leaf panels is formed by cold rolled galvanized steel plates through rolling; each door leaf panel covers the outer side of the corresponding framework to form a two-layer flat box body; composite fireproof door core materials are injected into each two-layer flat box body; main bodies of two-layer door leaves are formed; the main bodies of the two-layer door leaves form an integral door leaf; a gap exists between the main bodies of the two-layer door leaves; the door leaves with the hollow middles are formed; an air inlet hole is formed in the lower end, corresponding to the hollow part, of each door leaf; the upper end and the side end of each door leaf are provided with exhaust holes; and the inner side surface and the outer side surface of each door leaf are provided with seam covering plates corresponding to door seams of the two door leaves. The steel heat insulation fireproof door has the advantages that the problem that the existing fireproof door cannot prevent fire and smoke from overflowing through the door seams; the integral flame-resistant or high-temperature-resistant performance of the fireproof door is poor; and the door can easily deform. The steel heat insulation fireproof door has the advantages that the all-around fireproof function is realized; the heated deformation of the door body after the fire catching can be prevented; and the flame and smoke overflowing can also be effectively prevented.
