      Introduction to frame steel structure:

When the cast-in-place concrete frame is used, the structure indicates good integrity and rigidity, if well designed and treated, it can achieve better seismic effect, and the beams or columns can be casted into a variety of required cross-sectional shapes. Frame steel structure is commonly used in large-span public buildings, multi-storey industrial plants and some special-purpose buildings, such as theaters, shopping malls, stadiums, railway stations, exhibition halls, shipyards, hangars, parking lots, light industrial workshops, etc.
