　　Steel-framed prefabricated houses, akin to building with LEGO blocks, involve prefabricating major components in a factory and assembling them on-site to complete the entire residential structure. This significantly reduces on-site construction work, shortens the construction period, ensures environmental protection during construction, and guarantees building quality and safety through standardized design and construction.

　　To realize the prefabrication of steel-framed houses, it is first necessary to standardize and productize the components, including the standardization of beams and columns, the productization of connection nodes, and the productization of walls, floors, and other components.

　　In addition to the main structure, the envelope structure supporting steel-framed buildings must not only provide insulation, soundproofing, moisture resistance, and rain protection but also be durable. Currently, there are hundreds of panel types in China, but not many perform well on their own or integrate well with the steel-framed main structure. The cost of envelope walls has a significant impact on the overall construction cost, and wall construction also significantly affects the overall construction schedule.

　　Steel-framed prefabricated buildings can achieve productized component production, mechanized on-site assembly, facilitate information management of the entire structure, reduce construction waste, minimize the adverse environmental impact of construction, improve building quality, and offer high material recovery rates. Aligned with the needs of building an ecological civilization, they will gain increasing application in the future construction market.
