What Materials Are Good for Prefabricated Houses

The choice of materials for prefabricated houses depends on specific needs and scenarios. Commonly used materials include steel structures, concrete, glass-fiber-reinforced plastic (GFRP) composites, and sandwich panels (fire-resistant and soundproof types). Below is a detailed analysis:

Steel Structure Materials

Composed of high-strength steel frames, they offer significant advantages: lightweight, reducing transportation and installation difficulties; strong earthquake resistance, suitable for earthquake-prone areas; short construction period, typically completing the main structure in a few days. Application scenarios include customized needs such as outdoor uniquely shaped B&Bs and creative hotels. For example, some scenic spots use steel-structured prefabricated houses for rapid renovation. However, it should be noted that steel may be at risk of rust when exposed to humid environments for long periods, requiring the use of anti-corrosion coatings.

Concrete Materials

Using integrated pouring techniques, their core characteristics are high structural stability, capable of bearing significant loads; excellent moisture and heat insulation, suitable for long-term living needs. A typical case is cement prefabricated houses in rural areas of Henan, with a cost of only 300 yuan per square meter. A 200-square-meter villa costs about 60,000 yuan in total, and the main structure can be completed in just 4 hours, offering outstanding cost-effectiveness. However, concrete materials are heavy, leading to higher transportation costs, and require on-site pouring during construction, offering slightly less flexibility than other materials.

Glass-Fiber-Reinforced Plastic (GFRP) Composite Materials

Based on glass fiber-reinforced resin, they possess corrosion resistance and pressure resistance characteristics and are lightweight for easy transportation. Their application scenarios are concentrated in special environments: coastal high-salinity areas can avoid metal material rust; chemical parks and other corrosive environments can extend building lifespan; industrial equipment protective covers and other scenarios also widely adopt them. However, GFRP materials are costly and require professional processing equipment, suitable for scenarios with stringent weather resistance requirements.

Sandwich Panel Materials (Fire-Resistant and Soundproof Types)

Using rock wool fireproof boards as core materials, their core advantages are high fire resistance ratings, meeting building fire safety regulations; sound insulation effects up to 40 decibels, effectively blocking noise. Typical applications include high-noise environments such as construction site dormitories and industrial plants, as well as public buildings with strict fire safety requirements. However, sandwich panel materials have lower strength and need to be used in conjunction with steel frames, and there may be a risk of core material settlement after long-term use.

Material Selection Recommendations

• Cost Priority: Concrete prefabricated houses offer the highest cost-effectiveness but require weighing transportation costs.
• Rapid Deployment: Steel-structured or container-type prefabricated houses are easy to install and suitable for emergency scenarios.
• Special Environments: Choose GFRP for high-salinity areas and fire-resistant sandwich panels for high-noise scenarios.

In addition, auxiliary materials such as grout (used for connecting prefabricated panels) and mineral wool core materials (for sound insulation) can be selected as needed to enhance overall performance.
