Design: Modern household elements are introduced into the design of container trailer, which can be combined and superimposed at will with a single box as a unit, and has better performance in sealing, sound insulation, fire prevention, moisture prevention and heat insulation. The design of prefabricated houses is based on raw materials such as steel and plates, and they are installed on site. The performance of sealing, sound insulation, fire prevention, moisture prevention and heat insulation is poor, and the effect will not be known until the installation is completed, which is not conducive to people's comparative choice. Structure: The container trailer is a whole structure, which is welded and fixed, making it more secure, wind-resistant and earthquake-resistant, and will not fall apart or collapse in case of typhoon, earthquake, land subsidence and other disasters; The prefabricated house is a mosaic structure, which has low resistance, and it is easy to collapse and fall apart in case of unstable foundation, typhoon and earthquake, and it is not safe enough. Decoration: The floor of container trailer is paved with tiles, walls, ceilings, water and electricity, doors and windows, exhaust fans, etc. One-time decoration, permanent energy saving, environmental protection and beautiful appearance; However, the walls, ceilings, water pipes, circuits, lighting, doors and windows of prefabricated houses need to be installed on site, which is long in construction period, high in cost and not beautiful enough. Installation: the container trailer can be hoisted in the whole box without concrete foundation, and it can be installed in 15 minutes, moved in 1 hour, and can be used after being connected to the power supply; The installation of prefabricated houses requires concrete foundation, main body construction, wall installation, suspended ceiling and water and electricity installation, which takes a long time. Through the comparison of the above aspects, we can intuitively see that container prefabricated houses have great advantages, but at present, the market recognition of prefabricated houses is very high and mature.
