Compared with brick-concrete structure, prefabricated house has more dynamic and sleek shapes with better thermal insulation performance, and wall surfacing materials of different textures can create many architectural styles; compared with wooden structure, prefabricated house is more cost-effective. Materials for light steel villa are mostly environmentally friendly green building products. In addition, small section size and light dead weight of cold pressing steel joist frame has 5~8% more construction area use ratio than traditional structures, so basic cost is reduced. One point more worth noting is that light steel villa system requires simple construction process and project term — in construction of one 2-storied prefabricated house with an area of approximately 300㎡ , project term of main structure is only 1 month if there are 5 construction workers for construction.
