Disadvantages of Container Houses

The disadvantages of container houses are mainly reflected in three aspects: fire safety hazards, inadequate living performance, and compliance risks:

1. Prominent Fire Safety Hazards

Container houses are mostly supported by steel structures. In a fire, the temperature in the fire scene can reach 800-1000℃, far exceeding the critical temperature (500℃) at which steel structures lose stability. Ordinary container panel houses may collapse within 10 minutes after a fire, making it difficult for personnel evacuation and material rescue. In addition, some low-priced products use flammable materials such as polyurethane and polystyrene to fill the panel cores. These materials have low ignition points and poor flame retardancy. When exposed to high temperatures or open flames, they will burn rapidly and even exacerbate the spread of the fire due to their honeycomb structure. In some cases, electrical circuit failures ignite weeds or flammable materials, eventually leading to serious fires, causing property damage and even casualties.

2. Defects in Living Performance

Container houses have a small internal space, poor ventilation and lighting conditions, and long-term residence can easily lead to a sense of oppression. The sound transmission effect of metal materials is strong, and the sound insulation performance is insufficient, requiring additional treatment to reduce noise interference. The thermal insulation performance of low-end products is difficult to guarantee, making them stuffy in summer and cold in winter. Choosing higher-quality products (usually twice the price of low-end products) is necessary for improvement. In addition, steel is at risk of rusting in humid environments. If fire prevention and anti-corrosion treatments are not in place, it may affect the structural safety.

3. Compliance and Safety Risks

Some container houses are identified as illegal structures because they do not comply with urban appearance standards or building regulations. For example, a hotel used container panel houses as staff dormitories and tried to hide them from view by planting bamboo, but was eventually removed by law enforcement authorities. Illegal use not only affects the city's appearance but may also bring safety hazards due to structural instability and lack of fire protection facilities. In addition, container houses are not designed for long-term residence. Their internal layout is compact, and the configuration of living facilities is limited, resulting in low comfort for long-term residence.
