Nailing in Container Houses

Container houses can be nailed, but caution must be exercised based on the type and structure of the house to avoid damaging internal circuits or affecting structural stability.

1. Differences in Container House Types and Structures
   Container houses fall into two categories: those directly converted from shipping containers, retaining the original metal frame and wall panels; and factory-customized modular houses, using color-steel sandwich panels or light steel structures. The former has thicker wall panels (usually 2-3mm) that can withstand a certain amount of external force; the latter has thinner wall panels (0.6-1mm) and may have pre-buried circuits inside, making random nailing a potential safety hazard. For example, in a case in Haiyan, Jiaxing, a container house experienced wall panel detachment during strong winds due to shallow nail fixation, exposing structural connection issues.

2. Nailing Tools and Operating Specifications
   If decorative elements or partitions need to be fixed, it is recommended to use a pneumatic coil nailer. This tool drives a nailer through compressed air, allowing for quick insertion of coiled nails with lengths ranging from 19-45mm, suitable for wood structure connections or thin metal panel fixation. When operating, note the following:

• Air Pressure Control: The working air pressure range is 0.49-0.83MPa. Excessive pressure may cause metal deformation or nail penetration through the wall panel.
• Nailing Depth Adjustment: Some models are equipped with knobs to adjust the nail embedding depth according to material thickness, avoiding nail head exposure or loose fixation.
• Avoid Circuit Areas: The roof and side walls of customized container houses may have pre-buried wires. Before nailing, confirm the circuit layout to prevent electric shock or short circuits.

3. Structural Safety and Maintenance Recommendations

• Prohibit Random Drilling: The frame connectors (such as bolts and angle irons) of container houses must remain intact. Unauthorized drilling may weaken the overall wind and earthquake resistance. For example, the leased packed container houses in Erdos explicitly require that the connection accessories between the glass curtain wall and the frame be provided by the manufacturer to ensure sealing and structural stability.
• Regularly Inspect Fasteners: After long-term use, nails or bolts may loosen due to vibration. Regularly tighten and inspect the connections between the wall panels and the frame to prevent water infiltration or air leakage.
• Professional Modification Requirements: If windows, doors need to be added or the layout needs to be modified, contact the manufacturer or a professional team to use welding or riveting processes instead of relying solely on nails for fixation.

4. Solutions for Special Scenarios
   In temporary setups or creative renovations (such as container shops or offices), removable connectors (such as hooks or magnetic fixtures) can be used instead of nails to protect the house structure and facilitate later layout adjustments. For example, container shops in Shanghai's cultural and creative park create an atmosphere with hydraulic folding bars and LED light strips without damaging the wall panels for functional expansion.
