Zhaoqing Container Box House

The container box houses in Zhaoqing mainly include types such as packing-box units, light steel keel structures, and functional booths. They are characterized by environmental protection, energy efficiency, flexible combination, and convenient transportation, but attention should be paid to fire safety risks.

I. Product Types and Characteristics

1. Packing-Box Container Houses
   These houses use hot-dip galvanized cold-formed steel frames paired with fire-resistant polyurethane sandwich panels, providing thermal insulation and fire resistance. They can be used independently or stacked in multiple layers, suitable for construction site dormitories, office areas, and temporary meeting rooms. For example, some manufacturers in Zhaoqing produce modular Apple Pod mobile homestays with similar structures, supporting rapid assembly and cross-border transportation.

2. Light Steel Keel Houses
   These houses adopt cold-formed thin-walled light steel keels as the load-bearing structure, with walls filled with insulation materials. Their appearance and layout can be flexibly customized, making them suitable for self-built houses, homestays, and supporting facilities in scenic areas, meeting personalized needs.

3. Functional Booths and Supporting Houses
   Their sizes and internal layouts can be adjusted according to actual needs, commonly found in security booths, property booths, and environmental protection public toilets. For example, modular integrated houses exported from Zhaoqing to Hong Kong for the "Simple Public Housing" project demonstrate the large-scale application of functional houses.

II. Application Scenarios and Advantages

Container box houses are widely used in construction sites, field operations, office buildings, and temporary housing in tourist attractions due to their environmental protection, energy efficiency, flexible combination, and convenient disassembly and transportation. As an important node city in the Guangdong-Hong Kong-Macao Greater Bay Area, Zhaoqing has become an important production and export base for modular building products, leveraging its industrial foundation and geographical advantages, with a significant increase in export volume in the first quarter.

III. Fire Safety Risks and Prevention

1. Fire Hazards
   Some container houses use flammable materials such as polystyrene and polyurethane foam to save costs, posing risks of ignition from electrical welding sparks and cigarette butts. For example, container house fires have occurred in Hangzhou and Langfang, causing property damage and even casualties.

2. Prevention Measures

   • Material Selection: Prioritize the use of Class A fire-resistant materials such as rock wool boards and fireproof cotton.
   • Safety Distance: Maintain a minimum distance of 6 meters between houses.
   • Electrical Safety: Protect wires with sleeves, and use metal galvanized boxes for sockets and switch boxes, which should be installed openly.
   • Fire Extinguishing Equipment: Equip both inside and outside with simple fire extinguishing devices, and maintain a safe distance during open flame operations.
