Container House Panel Requirements
When attaching panels to container houses, it is essential to focus on material, installation joints, fire prevention, and corrosion resistance requirements, as detailed below:

Material Requirements
The wall panels of container houses typically use 75mm-thick rock wool color-coated steel sheets, with a color-coated steel sheet thickness of 0.5mm, meeting fire prevention, thermal insulation, and structural strength requirements. The roof requires 100mm×100mm×2mm galvanized square steel tubes as the framework to ensure load-bearing capacity. The flooring materials should be laid in layers: main joists use 50mm×100mm galvanized pipes, secondary joists use 40mm×80mm galvanized pipes, and the surface is covered with 15mm-thick particleboard to provide a flat and durable floor base.
Installation Joint Requirements
- Doorway Reinforcement: The area above the doorway must be reinforced, using galvanized reinforcement strips or additional framework support to prevent deformation after long-term use.
- Internal Corner and Steel Column Covering: The internal steel columns and corners of the room should be wrapped and decorated with color-coated steel sheets to enhance aesthetics; the galvanized reinforcement strips at the doorway should retain their original color without painting to preserve corrosion resistance.
- Exposed Wall Surface Treatment: The exterior wall panels should be recessed by approximately 2.5cm, with the inner side flush as the standard, ensuring wall flatness. The corridor wall (on the side with the door) should be flush with the outer side of the column to maintain overall neatness.
- Joint and Disassembly Design: The floor panel joints should reserve a 500mm-wide disassembly block for easy later disassembly and maintenance, with clear markings made.
Fire Prevention and Safety Requirements
- Filling Materials: Rock wool panels or fireproof cotton must be used as fillers, achieving an A-grade fire resistance limit, in compliance with construction site fire safety standards.
- Electrical Layout: Wires must be protected with sleeves, and sockets and switch boxes should use metal galvanized boxes and be surface-mounted to prevent fires caused by electrical faults.
- Safety Distance: Container houses must maintain a safety distance of at least 6 meters from each other to prevent the spread of fire.
Corrosion Resistance and Durability Requirements
- Coating Process: The container body surface must undergo hot-dip galvanizing treatment, which has a significantly longer corrosion resistance life than cold galvanizing, especially suitable for areas with large diurnal temperature variations and significant humidity changes.
- Cutting and Welding Treatment: All cutting and welding edges must be polished smooth and painted with epoxy primer + topcoat to prevent rusting.
