In the decoration integration of steel structure, overhead floor achieves a separation of decoration and structure. Overhead floor system is composed of steel bracket, beam and floor. Reasonable overhead floor structure to ensure the safety of the whole structure has important significance. In this paper, the new form of beams named the cold bending cap steel is proposed and the size design of the new beam is made. While maintaining the original beams on the basis of mechanical properties, the new form of beams increase effective use height above the floor. In addition, the construction technology, construction requirements, the error control of overhead floor system, etc. are summarized and some author's suggestions in terms of modular are made.
