The invention discloses a steel structure construction site material visual intelligent management system, which comprises BIM model memory, a central data processor, a two-dimensional code printer, a mobile terminal and the like. A created steel structure and a site BIM model are introduced into the system, and a two-dimensional code storing component geometric information and machining process information is generated and then stuck on a component. When the component is transported to a construction site, the two-dimensional code is scanned and giving storage yard information to the component, a component color in the BIM model is automatically changed according to pre-set storage yard color characteristics, that is, the component color is automatically matched with the color of the storage yard for temporary storage. The steel structure construction site material visual intelligent management system improves the management level of the construction site by adopting the information means, reduces waste of construction resources, and guarantees the smooth realization of project progress, quality and safety goals.
