Prefabricated Mobile Housing
Prefabricated mobile housing is a building form where components are prefabricated in factories and then assembled on-site, featuring various types and characteristics.
Modular Buildings: These buildings are broken down into independent modules, with ceilings, floors, and utility lines manufactured in factories and then transported to construction sites for assembly. Compared to traditional construction methods, they offer significant advantages, including short construction periods, with durations reduced by over 60%. For example, a public housing project in Shenzhen, Guangdong, saw its completion and delivery time reduced from 2.5 to 3 years to just 1 year. Quality is controllable, with on-site labor reduced by about 50%, significantly minimizing noise, dust, construction waste, and traffic congestion that disturb residents. Additionally, they are easy to maintain and energy-efficient. However, this model requires a highly developed industrial base, including technical systems, production systems, and industrial clusters.
Mobile Panel Houses: These are eco-friendly and economical temporary buildings with light steel frames and sandwich panels as enclosure materials. They use standard modular design and bolt connections, with components prefabricated in factories and then assembled on-site following standardized procedures. They are detachable and easy to transport, with customizable areas ranging from 15 to 160 square meters, suitable for various terrains such as hillsides and grasslands. Main types include cement mobile houses with steel structure supports, lightweight and low-cost phosphorus-magnesium mobile houses, and color steel plate mobile houses with excellent thermal insulation (using colored-coated polyethylene foam sandwich panels with a lifespan of 10 to 20 years). Mobile panel houses are formed by extruding a foamed polypropylene insulation layer and an iron sheet outer layer, with staggered connections during assembly to enhance sealing. Prices vary based on materials and region, with common 5 cm 950-type EPS sandwich panels costing about 35 yuan per meter, single-slope flat-top color steel houses about 230 yuan per square meter, and galvanized components reusable for 20 years. During fire inspections, emphasis is placed on checking escape routes, and case training is used to enhance fire prevention awareness among construction site personnel.
Prefabricated Cement Mobile Houses: Examples include Xiaozhaidi prefabricated cement mobile houses. For instance, a popular model from Xiaozhaidi this year has a width of 3.6 meters, including eaves, and is fully equipped with switches and other facilities inside the room.
Market Situation of Prefabricated Mobile Housing: There are numerous brands, such as Baitai and Xinwei Hongtu. Materials include concrete, cement, and sandwich panels. Construction methods include welding and assembly. Styles include temporary buildings, two-story mobile houses, assembled types, and light steel mobile houses. Product parameters involve load-bearing capacity, assembly methods, and snow load resistance.
