Simple Container House

Simple container houses generally refer to movable and modular houses that are either modified from standard containers or designed based on the structural principles of containers. They have characteristics such as rapid deployment, flexible combination, and controllable costs, and are widely used in temporary office, accommodation, commercial, and emergency scenarios. The following is an introduction from the aspects of types, structural performance, application scenarios, and key selection points:

Types and Structural Characteristics

1. Container-type: Based on standard 20-foot and 40-foot containers, they are transformed into independent office or living units through reinforcement, window opening, and heat insulation modifications. The advantages are a sturdy structure and convenient transportation, suitable for long-term on-site or project department use. For example, the standard container houses of CIMC Modular Building Investment Co., Ltd. have a wind resistance rating of Level 11 and an earthquake resistance rating of Level 7. They can be used as a single unit or combined with multiple units to expand the space.
2. Foldable-type: Using hydraulic or mechanical folding structures, their volume is compressed to 1/4 to 1/5 of the expanded state during transportation. A single truck can load 15-20 sets, significantly reducing transportation costs. The foldable container of Suzhou Zhongnan Steel Structure Co., Ltd. can be expanded in just 5 minutes, suitable for emergency rescue and short-term turnover scenarios.
3. Assembled-type: Assembled on-site in a modular way with light steel keels and color steel plates, they can be flexibly expanded according to the number of people and functions. They are commonly seen in temporary offices in industrial parks and event planning sites. The quick-assembly container of Yazhi Integrated Housing Co., Ltd. takes 4 hours to install and supports basic assembly.
4. Expandable-type: Additional side or end expansion cabins are added to the containers. After expansion, the usable area increases by 30%-50%, suitable for long-term office or accommodation scenarios with high requirements for space comfort.

Core Performance and Compliance Requirements

• Structural stability: It needs to comply with the GB50011-2010 Code for Seismic Design of Buildings, and the wind resistance rating is usually required to be above Level 8. Products from leading manufacturers, such as the packing containers of Suzhou Zhongnan, have a wind resistance of Level 12 and an earthquake resistance of Level 8, with a frame deformation rate of only 0.18%, far lower than the industry's qualified threshold of 0.3%.
• Fire resistance: The national standard requires a rating of above B1. Compliant products use fire-retardant materials, which can effectively delay the spread of fire.
• Environmental protection and reusability: They support multiple disassembly and assembly cycles for reuse. Products from leading manufacturers can be disassembled and assembled an average of more than 8 times, reducing construction waste emissions by about 90%, which is in line with low-carbon construction policies.

Key Selection Indicators

1. Scenario adaptability: Select the type according to the usage cycle (short-term turnover/long-term on-site) and relocation frequency (frequent relocation/fixed use). For example, exploration teams should choose foldable-type, and temporary buildings in industrial parks can choose assembled-type.
2. Installation efficiency: Products with a high degree of prefabrication can be hoisted on-site in just a few hours, while non-standard products may take 2-3 days, affecting the project delivery node.
3. Transportation and storage costs: The foldable containers have a small volume after folding, increasing the single transportation volume by more than 60% and reducing long-term storage space costs by 30%-50%.
4. Compliance qualifications: Export products need to have international certifications such as CE and ISO. Domestic government and enterprise projects require manufacturers to provide wind and earthquake resistance test reports, environmental protection certifications, and after-sales service networks.
