Features: Steel structure mobile house is a kind of environmentally friendly and economical mobile house with light steel as the skeleton, sandwich board as the enclosure material, space combination through standard modulus series, and bolt connection of components. It has the advantages of low cost, fast construction speed, convenient assembly and disassembly. It has realized the general standardization of temporary buildings and established the building concept of environmental protection, energy saving, fast and efficient. Application scenario: It is widely used in temporary offices and dormitories on construction sites. Also suitable for transportation, water conservancy, oil, natural gas and other large field exploration, field operation construction. Module room refers to the building materials are processed into standardized modules in advance, assembled in the factory, and then transported to the site for assembly of the house. Comply with state and local housing regulations, which are often stricter than federal regulations. It has the advantages of fast construction, low carbon environmental protection and personalized customization. The various parts of the house are tightly constructed when leaving the factory and the connection points at the site connections are of high quality. A factory built home may be safer than a similar conventionally built home because the individual parts are assembled in a factory and assembled on site, with more frequent inspections. Prefabricated housing refers to a house that is mostly built in a factory, transported to a permanent location, and assembled on site on a foundation. Prefabricated housing solutions are different from "stick building" (houses built the traditional way). It has the characteristics of fast construction, low carbon environmental protection, energy saving and high efficiency. The materials are not susceptible to weather degradation, and the compact building envelope improves energy efficiency
