Hainan Prefabricated Housing Finished Products

Hainan prefabricated housing finished products encompass a variety of types, including mobile panel houses, light steel movable houses, temporary buildings, and container prefabricated houses, characterized by diverse core materials, a wide range of application scenarios, and advanced manufacturing technologies.

I. Types and Core Materials
Prefabricated housing finished products in Hainan are centered around modular design, with common types including:

1. Mobile Panel Houses: These feature a lightweight steel structure as the framework, paired with polyurethane or rock wool core materials. They offer rapid assembly and disassembly, as well as mobility, making them suitable for temporary office or living scenarios.
2. Light Steel Movable Houses: Utilizing galvanized light steel keels and filled with fiberglass or rock wool, these structures are lightweight and offer excellent thermal insulation. They are commonly used in tourist homestays or public service facilities.
3. Container Prefabricated Houses: Based on standard shipping containers, these houses are transformed to provide living functions. The core material is mostly polyurethane, offering high strength and waterproofing, suitable for emergency shelter or construction site dormitories.
4. Temporary Buildings: Often constructed by assembling concrete prefabricated components, these buildings have strong load-bearing capacity and are suitable for long-term temporary structures, such as public facilities in rural revitalization projects.

II. Application Scenarios
Prefabricated houses have a wide range of application scenarios in Hainan, primarily concentrated in the following areas:

1. Tourist Homestays: Light steel movable houses and container houses are popular choices for coastal or mountainous homestays due to their flexible design and modern appearance. They can be quickly erected and adapt to complex terrains.
2. Public Service Facilities: Temporary buildings such as schools and hospitals utilize concrete prefabricated components or curtain-wall movable houses to meet seismic and wind resistance requirements, ensuring safety.
3. Emergency Shelter Houses: Container houses, with their convenient transportation and rapid installation, are often used for temporary shelter after typhoons or floods, capable of withstanding winds of over 12 levels.
4. Rural Revitalization Projects: Prefabricated houses reduce construction costs through modular design while incorporating anti-corrosion coatings and ventilation structures to adapt to Hainan's high salt spray and humidity environment, extending their service life.

III. Pricing and Manufacturing Technologies
Prices vary depending on the type and specifications: container houses cost approximately 4500 yuan per set, curtain-wall movable houses cost about 100 yuan per square meter, and prefabricated concrete houses cost around 1000 yuan per square meter.
In terms of manufacturing technology, factories in Hainan adopt BIM full-process digital management to achieve collaborative optimization in design, production, transportation, and installation, reducing errors and construction periods. Additionally, they independently develop anti-corrosion coatings and ventilation structures to optimize material corrosion resistance in high salt spray environments and significantly enhance building durability through forced ventilation design to reduce internal humidity.
