Light Steel Prefabricated Panel House

The light steel prefabricated panel house is a low-rise residential building system constructed using light steel keels as the core material, with factory prefabrication and on-site assembly. It offers advantages such as light weight, earthquake and wind resistance, and energy efficiency, making it suitable for rural housing, tourist resorts, and other scenarios.

Materials and Structural Features**: The light steel prefabricated panel house uses light steel keels cold-rolled from hot-dip galvanized aluminum steel strips as its framework. The galvanized aluminum-zinc steel plate is formed by a quaternary crystal structure consisting of 55% aluminum, 43.4% zinc, and 1.6% silicon, solidified at 600℃, creating a dense anti-corrosion barrier that effectively resists environmental erosion from moisture and salt spray, extending the building's lifespan. The exterior walls are filled with glass fiber wool for thermal insulation, and are equipped with breathable membranes to regulate humidity, enhancing living comfort.

Construction Method and Efficiency: Adopting a prefabricated building model, the house is divided into independent modules (such as walls, floors, and roofs), which are prefabricated and inspected in the factory for structural, mechanical, and electrical, and decorative integration before being transported to the site for assembly. The construction period is 30%-50% shorter than that of traditional buildings. For example, a homestay can be completed in 30 days, significantly reducing on-site wet work and labor dependence, with material waste reduced to 3%.

Performance Advantages:

• Light Weight: Only 1/5 to 1/8 of the weight of traditional brick-and-mortar structures, reducing foundation load requirements and making it suitable for areas with complex geological conditions.
• Earthquake and Wind Resistance: The main structure is designed with flexible connections, achieving an earthquake resistance of magnitude 9 and wind resistance of up to level 12, making it adaptable to earthquake-prone or typhoon-affected regions.
• Energy Efficiency and Environmental Protection: The roof supports the integration of photovoltaic tiles, improving energy efficiency by 40%. The overall cost is 15%-20% lower than that of brick-and-mortar structures, and the construction process generates no construction waste, meeting green building standards.

Application Scenarios and Policy Support: Widely used in rural self-built housing, tourist homestays, overseas aid projects, and other fields. Currently, 28 provinces across the country have introduced subsidy policies for prefabricated buildings, promoting the industry's large-scale development.

Market Price Variations: Prices vary significantly depending on the manufacturer, specifications, and configuration. For example, the wholesale price of modular houses for foreign trade is approximately 5 yuan per square meter (based on a monthly sales volume of 1 square meter), double-story light steel villa prefabricated modules cost about 198 yuan per square meter (based on a monthly sales volume of 8 square meters), and customized portable container mobile homes are priced at around 9,500 yuan per set, with choices depending on specific needs.
