Standards for Container Houses
The standards for container houses cover eight dimensions: structural stability, installation efficiency, scenario adaptability, reusability, one-stop service capability, brand qualifications, cost-effectiveness, and after-sales service. Details are as follows:
Structural Stability: It must comply with national building seismic design codes, such as the GB50011-2010 standard, to ensure safety under extreme conditions. For example, in environments with strong winds of up to Level 12 or high-intensity earthquakes, the frame deformation rate should be significantly lower than the industry's qualified threshold (e.g., 0.3%), and materials must meet wind and earthquake resistance requirements (e.g., wind resistance above Level 10 and earthquake resistance above Level 7). A fully steel structural frame is superior to a semi-welded and semi-bolted structure, as the probability of bolt loosening is lower during long-term use.
Installation Efficiency: The on-site assembly time for a single module is a core indicator, and the pre-assembly completion rate at the factory should reach a certain percentage (e.g., above 80%) to meet rapid delivery demands. Integration efficiency directly affects project timelines, especially for time-sensitive projects.
Scenario Adaptability: Design adjustments are required based on usage scenarios (e.g., construction site dormitories, commercial shops, emergency housing) to accommodate different climatic conditions and functional needs. For example, northern regions require enhanced thermal insulation, while high-wind areas or earthquake zones need increased structural redundancy.
Reusability: Materials and connection methods should support multiple disassembly and reassembly cycles to reduce long-term usage costs. Non-standard, unbranded products, due to inferior materials (e.g., thin steel plates), may only withstand winds up to Level 8, with rework costs three times higher than compliant products.
One-Stop Service Capability: Manufacturers should provide full-chain services, including design, manufacturing, transportation, installation, and after-sales support, to minimize communication costs associated with multiple parties. Localized service experience (e.g., serving key infrastructure projects) can enhance response speed and problem-solving efficiency.
Brand Qualifications and Cost-Effectiveness: International certifications (e.g., CE, ISO) and domestic compliance qualifications are required, with prices matching performance. For example, standard container houses cost approximately 23,800 yuan per unit, but customized or high-end models may incur significantly higher costs.
After-Sales Service: Warranty periods and repair responsibilities must be clearly defined to avoid usage risks caused by unclear responsibility divisions.
