Common Questions About Container Houses

Answers to common questions about container houses are as follows:

1. Specifications, Dimensions, and Load-Bearing Capacity Container houses fall into two categories: one type is directly modified from shipping containers, with common specifications of 20 feet (length: 6.06 meters, width: 2.44 meters, height: 2.59 meters) and 40 feet (length: 12.19 meters, width: 2.44 meters, height: 2.59 meters). The load-bearing capacity varies significantly depending on the material and craftsmanship. The other type is custom-made in factories according to container dimensions, with load-bearing capacity optimized through structural design. Specific parameters need to be determined based on the technical documents provided by the manufacturer.

2. Service Life The service life ranges from 2 to 30 years, influenced by materials, anti-corrosion treatment, and usage environment. For short-term projects (<5 years), ordinary rock wool panel container houses can be chosen. For long-term use (>10 years), it is recommended to invest 10-15% of the cost in anti-corrosion upgrades, which can increase the service life by more than 50% and reduce the total holding cost by 20%.

3. Wind and Earthquake Resistance The wind resistance rating is not specified, but stability can be enhanced through the following measures: ensuring secure container connections (e.g., bolt tightening), checking structural stability during installation, and conducting a comprehensive safety inspection after completing the top frame. The earthquake resistance rating is not mentioned specifically and needs to be evaluated based on design specifications and construction standards.

4. Fire and Water Resistance The fire and water resistance ratings are not specified, but they can be improved through material selection and process optimization. For example, using fire-resistant rock wool panels as wall materials or applying waterproof coatings to seams.

5. Environmental Protection and Recycling The core advantage of container houses is their reusability. The container body is connected with bolts, allowing disassembly without damaging the main structure, with a single container disassembly time of less than 30 minutes. Wall panels are installed using slot-in methods and can be completely recovered after removal. The circuit is designed with pre-embedded quick connectors, enabling zero-loss disassembly and reassembly of the water and electricity systems.

6. Installation Complexity

• Foldable container houses: Professional teams can unfold the main body within 3 minutes. After hoisting into place, they can be used immediately, with a single person able to operate the hoisting process.
• Assembled container houses: The base, wall panels, and roof need to be connected in sequence, with bolt tightening and sealant application taking approximately 1-2 days per unit.
• Modular combined container houses: These are connected into multi-story buildings through welding or bolts. The installation period for a 3-story combined container house with 20 containers is typically 2-4 weeks.

7. Official Approval Procedures For temporary buildings (e.g., construction site dormitories) that do not affect urban planning, traffic, or safety, generally, only filing is required. For long-term residence or commercial use (e.g., homestays, shops), design planning drawings, land use certificates, and business licenses, fire permits, and other documents need to be provided.

8. Construction Precautions

• Choose containers with sturdy structures and good durability, prioritizing new containers or certified second-hand ones.
• Strengthen structural strength by adding supports, reinforcing connecting components, and applying anti-corrosion treatment.
• Use insulation materials to improve thermal insulation performance and conduct internal sound insulation treatment.
• Reasonably layout the space, focusing on ventilation and lighting, and adopting an open design.
• Ensure fire and electrical safety by using environmentally friendly materials and energy-saving technologies.
