Promoting the Development of Prefabricated Buildings

As a modern construction method, light steel villas have gained rapid popularity both domestically and internationally in recent years due to their unique advantages.

Compared to traditional brick-and-concrete structures, light steel villas offer a 10%-20% reduction in overall costs and a 30%-50% shorter construction period, making them ideal for post-disaster reconstruction or rapid development projects. The recyclability of steel reduces construction waste by 70%, aligning with the "dual-carbon" goals and attracting environmentally conscious consumers. With wall cavities filled with fiberglass or rock wool insulation, light steel villas achieve over 30% better thermal insulation than brick-and-concrete structures, ensuring energy-efficient temperature regulation and reduced air conditioning costs.

In China, many regions (e.g., Jiangsu, Zhejiang, Guangdong) provide subsidies (up to 50 RMB per square meter) or floor area ratio incentives for prefabricated residential projects using light steel structures, accelerating the adoption of green building practices.

Technological advancements, such as galvalume steel plates and fire-resistant coatings, have enhanced the fire resistance of light steel villas to over 2 hours, addressing traditional concerns. The lightweight steel frame structure (only 1/5 the weight of brick-and-concrete) offers high ductility, enabling resistance to magnitude 8-9 earthquakes and Category 12 typhoons, making it suitable for seismic zones and coastal areas. High-strength bolts and galvanized steel connections ensure structural integrity, minimizing cracks and deformation.

Wide Application Scenarios for Light Steel Villas:  1. Rural Self-Built Housing: Fast construction and cost-effectiveness make it ideal for rural revitalization projects  2. Eco-Tourism Homestays: Modular construction suits scenic area development, blending seamlessly with natural surroundings  3. Emergency Shelters: Rapid deployment for post-disaster temporary housing or military camps.
