       In 2000, under the condition of "no precedent and no standard" in technology, Hangxiao steel structure cooperated with Zhejiang University, Tongji University and other universities to carry out the research on "complete set technology of rectangular concrete-filled steel tube structure", and created a concrete-filled steel tube structure system with more applicability, economy and fire resistance than pure steel structure, Ruifeng international business building, a domestic representative high-rise building with rectangular concrete-filled steel tubular structure, has been completed. This project has been listed as a national torch plan project, which has completely changed the traditional way of reinforced concrete construction, solved the problem of improving the fire resistance of steel structures, and has good seismic and fire resistance performance. The successful implementation of the project has established the technical position of Hangxiao steel♒ structure in the field of high-rise steel structure, formed a high-rise steel structure building technology system with Hangxiao characteristics, and promoted the development of domestic high-rise steel structure buildings.

       Hang Xiao edited and participated in the compilation of many industry and association standards, such as the technical specification for steel structures of high-rise civil buildings, the design specification for steel-con🧸crete hybrid structures of multi-storey and high-rise buildings, the technical specification for concrete filled rectangular steel tubular structures, and the technical code for design and construction of composite floors.

       Hangxiao steel structure has obtained more than 30 national patents relat🔥ed to concrete-filled rectangular steel tubular columns, filling the gap in the domestic "technology of using concrete-filled rectangular steel tubular columns in high-rise building structures", and reaching the international advanced level. Among them, "high-rise building steel-concrete composite structure technology" won the "National Green Building Innovation Award" of the Ministry of construction in 2005.

       Hangxiao steel structure has completed 𒈔500 + super high-rise ✱steel structure buildings in total.
