Container House Assembly Roof

The design, materials, and construction points of the assembly roof for container houses are as follows:

Assembly Roof Structure Types

The roof design of container houses needs to balance functionality and aesthetics. Common structures include flat roofs, pitched roofs (triangular roofs), and expandable roofs. Flat roofs have a simple design, suitable for scenarios such as schools and warehouses, with relatively low costs. Pitched roofs, like the triangular roof in the OostKampville project in Bangkok, achieve a balance of rain protection, daylighting, and ventilation through a combination of metal sheets, translucent materials, and louvers, making them suitable for tropical climates. Expandable roofs increase usable area through side or end expansion modules, enhancing spatial comfort.

Roof Material Selection

Roof materials need to meet requirements such as being lightweight, high-strength, and weather-resistant. FRP (fiberglass-reinforced plastic) container roof panels are a mainstream choice, featuring properties such as yellowing resistance, UV resistance, and impact resistance. They are suitable for tank containers, truck bodies, and modular houses. The price range is 10.07 - 134.23 yuan per square meter, depending on the material (such as EPS sandwich wall panel-type waterproof FRP sandwich roof panels) and performance (such as transparent heat-resistant fiberglass corrugated panels). In addition, some projects use a combination of metal sheets and translucent materials. For example, in the OostKampville project, the top metal sheets protect residents from heat and rain, while the middle translucent part introduces natural light.

Construction and Assembly Points

The roof construction of container houses should focus on modularization and on-site assembly efficiency. During the factory prefabrication stage, the main structure, interior decoration, and mechanical and electrical piping are completed, and the roof modules can be disassembled into independent units for transportation. During on-site assembly, only a few procedures such as module assembly and water and electricity connection are required, with almost no large-scale construction needed. For example, a modular housing project in North America transported four independent modules across the ocean and directly assembled them upon arrival to deliver fully furnished residential products, reducing the overall construction period by 60% - 70%.

Special Design Considerations

For specific climate or functional requirements, roof designs need to be adapted accordingly. Tropical climate regions (such as the Bangkok project) need to enhance ventilation and heat protection, achieving air circulation through steel plate louvers at the lower part of the roof. Cold or rainy regions need to increase the drainage slope and the thickness of the waterproof layer. In addition, the roof load should meet standards. A 20-foot container has a load capacity of about 25 tons, and a 40-foot container has a higher load capacity. During design, it is necessary to ensure that the roof structure matches the load-bearing capacity of the container body.
