Tongliang Modular Container House

The Tongliang modular container house is an integrated housing solution centered around modular design. It utilizes standardized container components and combines factory prefabrication with on-site assembly, offering rapid deployment, flexible combination, earthquake resistance, and fire prevention. It is widely applied in temporary buildings, municipal facilities, and self-occupancy scenarios. The following elaborates on its technical features, application areas, and industrial advantages:

I. Technical Features: Combining Standardization with High Performance
The Tongliang modular container house is based on ISO-standard containers, achieving Class A fire resistance and Grade 8 earthquake resistance through thickened galvanized steel coils and fireproof cotton processes, ensuring industry-leading structural safety. Its components are prefabricated in factories, with integrated systems for walls, floors, and electrical circuits completed in advance. On-site assembly only requires corner fittings to be tightened, reducing construction time by over 70% compared to traditional buildings. According to technical regulations, the building height is limited to 6 floors and 24 meters, with design service lives of 50 years (structural coefficient ≥1.0) and 25 years (≥0.95) to meet diverse needs. Additionally, the house employs light steel keels or plug-in structures, supporting horizontal splicing, vertical stacking, offset cantilevering, and other spatial combinations, enabling flexible adaptation to functions such as homestays, exhibition halls, and dormitories.

II. Application Areas: From Temporary Buildings to Permanent Residences
The Tongliang modular container house covers three main application areas:

1. Temporary Buildings: Preferred for construction site dormitories and emergency command centers due to rapid assembly/disassembly, reusability, simplified procedures, and lower costs than brick-and-mortar structures.
2. Municipal and Commercial Facilities: Standardized construction of scenic restrooms, campground kiosks, and urban public stations through modular combinations enhances construction efficiency.
3. Self-Occupancy and Customization: Some residents choose customized container houses for permanent living, benefiting from low costs, simplified approval processes, and personalized layouts via offset cantilevering and L-shaped enclosures. For example, Zhonglai Container Industry provided a house for the Nanchuan campground that was installed and operational within one day.

III. Industrial Advantages: Technology-Driven and Export-Oriented
Tongliang District has cultivated an assembly-building industry cluster led by Zhonglai Container Industry by revitalizing idle assets. As the southwest branch of Falilai Group, Zhonglai Container Industry operates an automated production line for Class A fireproof panels, with an annual output of 3,000 units and a production value of RMB 150 million. Its products, certified by the EU CE standard, are exported to countries such as Australia, Uganda, and Canada. Its technological strengths lie in two aspects:

1. Materials and Processes: Utilizing weathering-resistant welded steel (GB/T 4171) and Q345B non-container components ensures structural durability. Fireproof fillers prohibit EPS and other flammable materials, using Class A rock wool in crowded spaces with a fire resistance limit of ≥0.5 hours.
2. Intelligent Production: Digital management optimizes prefabrication processes, while on-site precision assembly achieves an efficient "building-like-LEGO" model. Currently, Tongliang District is promoting industrial upgrading through policy support, with export production value expected to reach RMB 40-50 million by 2025.
