Prefabricated Steel Structure for Housing

Prefabricated steel structure for housing is a building form that takes the steel structure system as the core and achieves efficient construction through on-site assembly of factory-prefabricated components. It has advantages such as earthquake resistance, environmental protection, and fast construction, and is widely used in fields such as residential housing and tourist resorts.

I. Process of Prefabricated Housing Steel Structures

Taking the Guose Space Capsule Apple Capsule Factory as an example, the main structure of the prefabricated housing steel structures it produces adopts specific size designs (such as a 150-millimeter specification). Standardized and modular processes are used to achieve factory production of components. This process reduces on-site wet operations, improves construction accuracy and efficiency, and facilitates quality control and material recycling. The main structure usually uses high-strength steel to ensure overall stability and durability, making it suitable for low-rise to multi-story building requirements.

II. Core Characteristics and Applications of Steel Structure Residential Housing

Steel structure residential housing uses systems such as steel frames and steel frame-bracing as the main load-bearing structures and adopts a prefabricated construction method. Its advantages include:

• Superior Performance: Good earthquake resistance, capable of withstanding high-intensity earthquakes; high space utilization with flexible layouts to meet personalized design needs.
• Green and Low-Carbon: Materials can be recycled, reducing construction waste; the construction process generates low noise and dust, meeting environmental protection requirements.
• Policy Support: Since 2016, the country has vigorously promoted prefabricated buildings, planning for steel structures to account for 10% of newly built residential housing by 2030 (currently around 7%). Typical projects such as Baotou Wanjun Metropolis and Hangzhou Qianjiang Century City Talent Special Housing have verified their feasibility.
• Challenges and Improvements: The industry is reducing construction costs through technological innovation, improving physical properties (such as sound insulation and fire resistance) and market acceptance.

III. Technical Advantages and Scenarios of Light Steel Villas

Light steel villas take light steel keels synthesized from hot-dip galvanized aluminum steel strips through cold rolling as the core. Combined with four major systems—foundation, wall, floor, and roof—they achieve fully prefabricated construction:

• Structural Performance: The self-weight is only 1/5 to 1/8 of that of traditional structures, with earthquake resistance up to magnitude 9 and wind resistance up to level 12, adapting to complex geological and climatic conditions.
• Energy Efficiency and Environmental Protection: The exterior walls are filled with glass fiber wool for thermal insulation, and are equipped with breathable membranes to regulate humidity; the roof supports the integration of photovoltaic tiles, improving energy efficiency by 40%.
• Economy: The construction period is shortened by 50% compared to traditional buildings, with material loss rates reduced to 3% and overall construction costs lowered by 15%-20%.
• Application Scenarios: Widely used in rural residential housing, tourist resorts, and overseas projects, with subsidy policies introduced in 28 provinces to promote their popularity. Exterior wall decorations can choose materials such as metal carved panels and cement fiber hanging panels, balancing aesthetics and durability.

Through process innovation and policy guidance, prefabricated steel structures are gradually becoming an important direction in the modern construction field, especially showing significant advantages in low-carbon, efficient, and flexible construction.
