A steel thermal-insulation fireproof door comprises a door frame and door leaves which are connected through hinges. A handle and a door lock are arranged on the door leaves. The fireproof door has the advantages expanded perlite are used as main materials of cement mortar in the door frame, re-expansion can be hard even if the door frame is on fire and heated, and accordingly, the heating and deformation of the door frame can be prevented; a framework and a plate of the door leaves are made of galvanized steel sheets, a door core is made of fireproof materials, and accordingly, the fireproof thermal-insulation effect can be achieved to a large extent; a fireproof door closing unit is arranged between the door frame and the door leaves, and the door leaves can be closed timely effectively, accordingly, the fire behavior and the hot gas can be blocked; meanwhile, the hinges, the lock and a door mirror are made of fireproof materials, so that a good fireproof thermal-insulation effect can be achieved through the overall action; a seam covering plate is added between the door leaves, fireproof expansion seal strips are arranged on a connection plate, and accordingly, the spreading of the fire behavior or smog can be prevented well.
