Requirements for Container Houses Used as Warehouses

When container houses are used as warehouses, they need to meet requirements for structural safety, fire safety compliance, environmental adaptability, and regulatory compliance, as detailed below:

1. Structural Safety Requirements

Container houses must have sufficient structural strength and stability to withstand the weight of stored goods and external loads. The frame material should be high-strength steel, such as CORTEN weathering steel or galvanized steel, ensuring wind resistance up to grades 10-12 and an applicable temperature range from -10℃ to 50℃. Walls and roofs should use fire-resistant and waterproof materials, such as rock wool panels or fireproof cotton filling, meeting Class A fire resistance standards to prevent fire spread. Additionally, container houses should support non-destructive disassembly and repeated relocation, remaining deformation-free and leak-proof after disassembly to ensure recyclability.

2. Fire Safety Requirements

When used as warehouses, fire safety is a core requirement for container houses. According to cases, some container houses have significantly increased fire risks due to the use of flammable materials like polystyrene or polyurethane foam as core materials. Therefore, filling materials must be non-combustible or difficult-to-ignite, such as rock wool panels, and electrical wiring should be avoided from being exposed or placed near heat sources. Container houses should maintain a minimum safety distance of 6 meters from each other to reduce the risk of fire spread. Meanwhile, simple firefighting equipment, such as fire extinguishers, should be equipped inside, and electrical wiring should be regularly inspected to prevent short circuits from causing fires.

3. Environmental Adaptability Requirements

Container houses need to adapt to different environmental conditions, such as humid, high-temperature, or low-temperature environments. Walls and roofs should adopt sound insulation and thermal insulation designs, such as air-gap thermal insulation structures, to reduce energy loss and lower energy consumption. The floor should have moisture-proof and corrosion-resistant properties, especially suitable for warehouses storing chemicals or moisture-sensitive goods. Additionally, container houses should support rapid deployment and flexible adjustment to meet the needs of temporary storage or long-term use.

4. Regulatory Compliance and Certification Requirements

When used as warehouses, container houses need to comply with relevant national and local standards, such as the Technical Standard for Modular Container Houses and the Facilities and Equipment Configuration for Emergency Shelters issued by the Ministry of Emergency Management. Manufacturers should have ISO9001 quality management system certification and provide third-party authoritative test reports or VoC compliance certificates. For export or overseas projects, they need to hold EU mandatory certifications such as CE and CPR(EU)305/2011 to ensure compliance.
