Container House Roof Panel Design

The design of container house roof panels requires selecting appropriate solutions based on different types. Common types and key design points are as follows:

1. Container House Roof Panel Design
Adopts a three-layer composite structural system:

• Base Layer: Retains the original corrugated steel plate of the container (thickness ≥ 2.0mm) as the structural support foundation.
• Intermediate Layer: Lays a 100mm thick rock wool board (density ≥ 120kg/m³) to provide thermal insulation and meet fire safety requirements.
• Surface Layer: Composed of a 1.5mm thick SBS modified bitumen waterproof membrane (waterproof layer) and a 0.8mm thick YX35-125-750 type color-coated steel plate (protective layer). Aluminum-plastic panels or anti-corrosion wooden cladding can be added externally to the color-coated steel plate as decorative layers.
  Drainage Design: The roof slope is set at 3%, adopting a single-slope drainage form. The drainage direction is from the middle of the container to the eaves on both sides, with the eaves overhang length controlled within 300mm.
  Keel Frame: Adds light steel keels above the original roof panel. The main keels use 8# channel steel (spacing 500mm, arranged along the length of the container), and the secondary keels use 50×30mm square steel tubes (spacing 600mm, perpendicular to the main keels) to enhance overall structural stability.

2. Quick-Assembly Container Panel House Roof Design
The roof and walls uniformly adopt a 50mm thick composite insulation panel, composed of double-layer color-coated steel plates sandwiching a polystyrene or rock wool core material.

• Structural Advantages: The color-coated steel plates provide impact resistance, while the core material meets both thermal insulation and fire safety needs. The overall structure is lightweight and easy for rapid assembly.
• Applicable Scenarios: Suitable for temporary buildings or scenarios with high requirements for construction efficiency.

3. Foldable Container House Roof Design

• Outer Roof: Uses 104-type color-coated steel tiles (thickness 0.5mm) with a corrugated design to promote drainage and reduce water accumulation risks; the top uses custom-shaped profiles to minimize nailing areas and reduce leakage rates.
• Internal Ceiling: Selects 831-type color-coated steel tiles (hardness 0.326mm) with fireproof, moisture-proof, and thermal insulation functions to enhance indoor comfort.
• Thermal Insulation Material: The top is filled with rock wool with a density of 60kg/m³ to enhance thermal insulation, sound insulation, and adapt to extreme climatic conditions.

4. Modular Container House Roof Design
Enhances structural stability through a pressed five-wave roof panel. The five-wave shape optimizes the drainage path, reduces rainwater retention time, and lowers leakage risks.

• Material Selection: The roof panel material must balance strength and corrosion resistance, typically using galvanized steel plates or aluminum alloy plates.
• Modular Advantages: The roof panel and other modules of the container are produced to standardized specifications, facilitating transportation and assembly, and suitable for large-scale applications.
