All components can be spliced and installed on site by the factory, making the construction fast and shortening the construction period. It has good seismic resistance and is environmentally friendly. Compared with the currently commonly used concrete structures, light steel structure integrated houses: First, they can be constructed dry, saving water, occupying less space for construction, producing less noise and less dust; second, due to reduced dead weight, less soil is required for foundation construction , less damage to the precious resource of land; third, the use of concrete and bricks is greatly reduced; fourth, when the service life of the building expires, less solid waste is generated from structural demolition, and scrap steel can be recycled.
