Disadvantages of Container Houses

The disadvantages of container houses are mainly reflected in structural safety, fire resistance, living comfort, and long-term usage costs, as detailed below:

1. Structural Safety Risks Non-standard container houses often use thin steel frames, with wind resistance ratings of only 6-7, far below the national standard requirement of over 8. In coastal or high-wind areas, issues such as frame deformation and wall cracking can easily occur, with rework costs reaching 30%-50% of the initial purchase cost. Additionally, the large transportation volume of folded non-standard products results in low single-trip transportation capacity, indirectly increasing costs.

2. Inadequate Fire Resistance Some small manufacturers use flammable materials like polystyrene and polyurethane foam as core materials to reduce costs, with fire resistance ratings of only Class C, far below the national standard requirement of Class B1. These materials burn rapidly, melting and dripping at 80℃, allowing fires to spread quickly and producing toxic smoke, making escape difficult. For example, container house fires have occurred in Hangzhou and Langfang, causing property damage and even casualties.

3. Poor Living Comfort

• Thermal Insulation Issues: Due to material differences, low-end products cannot guarantee thermal insulation performance, making them hot in summer and cold in winter.
• Poor Sound Insulation: Metal materials transmit sound significantly, requiring additional sound insulation treatment to reduce noise interference.
• Cramped Space: The interior space is relatively small, with insufficient ventilation and lighting, leading to a sense of oppression during long-term residence.
• Odors and Pollution: If the materials have poor environmental performance, they may produce odors due to environmental pollution, affecting health.

4. High Long-Term Usage Costs Exposed steel structures are prone to rust in humid environments, requiring regular anti-corrosion treatment; at high temperatures, steel strength decreases, necessitating professional fire-resistant cladding. If not properly maintained, the service life may be shortened, increasing long-term costs. Additionally, non-standard products may require frequent repairs due to quality defects, further driving up usage costs.

5. Safety Hazards Electrical circuit failures and improper open-flame operations can easily trigger fires, and since container houses are wrapped in iron sheets, water cannons have difficulty penetrating the interior during firefighting, increasing rescue difficulty. Some products have not passed quality inspections, posing structural safety risks and making them unable to withstand natural disasters such as earthquakes.
