Multi-story Building System

Multi-story steel structure system
	Relative to traditional reinforced concrete structure, the processing of multi-story steel structure system is more convenient, operated with machinery and high precision, which can effectively shorten the construction term and control construction quality.   Steel structure can greatly reduce its dead weight and save ground cost since it has the features of light dead weight and high strength. In addition, heat energy and airconditioning supply are saved because of the reduction of floorslab's thinckness and pillar's dimension.   Multi-story steel structure includes girder, secondary beam and column.Hot-roll steel or modular welding steel are generally used.   The floor is commonly made of steel floor carrier plate by pouring into reinforced concrete. The steel floor carrier plate has the following features: I.Replacing timber form as the permanent form panel makes the appearance more beautiful. II.Replacing concrete steel structure to resist bending moment.   Multi-story steel structure has becom the first choice of current industrial factory building with the features of variable structures and short construction cycle.
