Prefabricated Light Steel Structure House
The prefabricated light steel structure house is a low-rise residential building system with hot-dip galvanized aluminum steel strip cold-rolled light steel keels as its core material, offering advantages such as lightweight construction, high-efficiency earthquake resistance, and energy conservation and environmental protection.
Core Materials and Structural Characteristics
The core material of the prefabricated light steel structure house is the light steel keel synthesized from hot-dip galvanized aluminum steel strips through cold rolling. Its galvanized aluminum-zinc steel plate is formed into a quaternary crystal structure by curing 55% aluminum, 43.4% zinc, and 1.6% silicon at a high temperature of 600℃. This structure provides a corrosion-resistant barrier, effectively resisting environmental erosion from moisture and salt spray, thereby extending the building's service life. The building system comprises four major systems: foundation, wall, floor, and roof. It adopts a factory-prefabricated component on-site assembly model, with a self-weight only 1/5 to 1/8 of that of traditional brick-and-mortar structures, significantly reducing the foundation bearing pressure and making it suitable for regions with complex geological conditions.
Performance Advantages
- Strong Earthquake and Wind Resistance: The main structure is designed through standardized modular processes, achieving an earthquake resistance rating of magnitude 9 and a wind resistance rating of level 12, enabling it to withstand extreme disasters such as earthquakes and typhoons.
- High Construction Efficiency: Factory-prefabricated components reduce on-site workloads, shortening the construction period by 50% compared to traditional buildings, lowering material waste rates to 3%, and reducing overall costs by 15%-20% compared to brick-and-mortar structures.
- Energy Conservation and Environmental Protection: The exterior walls are filled with glass fiber wool for efficient thermal insulation, complemented by breathable membranes to regulate humidity and reduce energy consumption. The roofing system supports the integration of photovoltaic tiles, enhancing energy efficiency by 40% and meeting green building standards.
Application Scenarios and Policy Support
This building system is widely applied in rural residences, tourist resorts, and overseas projects, particularly suitable for scenarios with high demands for construction period and environmental performance. Currently, 28 provinces across the country have introduced subsidy policies for prefabricated buildings, promoting the development of the prefabricated light steel structure house industry and reducing users' initial investment costs.
