Disadvantages of Custom Container Houses

The main disadvantages of custom container houses include insufficient thermal insulation performance, poor sound insulation, fire safety hazards, limitations in structural stability and durability due to materials and craftsmanship, as well as high transportation and installation costs.

1. Insufficient Thermal Insulation Performance
   Due to differences in materials used, low-end container houses often struggle to provide adequate thermal insulation. For example, some products only meet basic requirements, and upgrading to better materials can double the cost. In extreme weather conditions, indoor temperatures are easily affected by the outside environment, necessitating additional air conditioning or heating equipment, which increases long-term usage costs.

2. Poor Sound Insulation
   The sound-conducting properties of metal materials result in poor sound insulation in container houses, allowing internal noise to escape and external noise to interfere with the indoor environment. To improve sound insulation, additional soundproofing materials or double-layer structures must be added to the walls, further increasing costs.

3. Prominent Fire Safety Hazards
   Some container houses use flammable materials such as polyurethane and polystyrene for panel cores, which have low ignition points and poor flame resistance. In the event of a fire source or electrical failure, fires can easily start and spread rapidly. Additionally, steel structures are prone to deformation and collapse under high temperatures, and narrow building passages can hinder personnel evacuation, increasing safety risks.

4. Limited Structural Stability and Durability
   Products from non-standard manufacturers often use thin steel materials, with wind resistance ratings of only 6-7, far below the national standard requirement of 8 or above. In coastal or strong wind areas, problems such as frame deformation and wall cracking are prone to occur. Furthermore, some products are not prefabricated, resulting in longer on-site installation times and potential delays in project delivery.

5. High Transportation and Installation Costs
   Although the transportation efficiency of foldable container houses is superior to that of traditional products, the folded volume of non-standard products is relatively large, limiting the amount that can be transported in a single trip and increasing transportation costs. Additionally, on-site installation requires professional teams, and if the manufacturer's service network is inadequate, project delays may occur due to untimely responses, resulting in additional losses.
