The invention discloses a steel core coextruded H beam. The beam comprises a middle beam body, an upper beam body and a lower beam body, wherein the upper beam body and the lower beam body are fixed on two sides of the middle beam body respectively; the upper beam body and the lower beam body are arranged symmetrically relative to the middle beam body, and each of the upper beam body and the lower beam body comprises a left supporting rod, a right supporting rod and a middle supporting rod; the left supporting rod and the right supporting rod are fixed at two ends of the middle beam body, and the middle supporting rod is positioned in the center position of the left supporting rod and the right supporting rod; and hollow holes are formed in the positions, near the left supporting rod and the right supporting rod respectively of the middle beam body, and a steel core is extruded in each of the hollow holes. The hollow holes extruded with the steel cores are arranged at the positions, near the left supporting rod and the right supporting rod, of the middle beam body of the steel core coextruded H beam, so that the strength of the middle beam body is effectively improved, and the stability of the H beam is effectively improved.
