Duplex Container House
A duplex container house is a type of container house that achieves double- or multi-story spatial layouts through modular assembly. It features characteristics such as disassembly and relocation, low-carbon recycling, and scene adaptability, with prices varying based on specifications and configurations.
I. Structural Features and Materials
Duplex container houses are typically assembled from multiple standard containers (such as 40-foot containers) through bolt connections or welding, forming double- or multi-story structures. For example, Guangzhou Jin Ge's duplex container house uses three 40-foot containers, with dimensions of 11.8m × 6.75m × 2.8m and a usable area of 80 square meters. In terms of materials, the main frame often uses galvanized steel structures, offering corrosion resistance and optimized load-bearing capacity. Walls and roofs are made of color-steel sandwich panels or rock wool sandwich panels, providing thermal insulation. Some high-end products also fill the space between the steel frame and interior wall panels with rigid polyurethane foam and add rubber thermal insulation pads to further reduce heat transfer efficiency.
II. Performance Advantages
- Disassembly and Relocation: Duplex container houses support multiple cycles of disassembly and reuse. On average, compliant products can be disassembled and reused more than 8 times, reducing construction waste emissions by approximately 90% compared to traditional fixed temporary buildings.
- Low-Carbon and Environmentally Friendly: They consume less steel, and materials can be recycled throughout their lifecycle, aligning with green construction policy guidelines.
- Scene Adaptability: Through modular assembly and customized exterior facades, they can adapt to diverse scenarios such as engineering camps, mobile commerce, cultural and tourism accommodations, and emergency response.
III. Pricing and Customization
Prices for duplex container houses vary based on specifications, materials, and configurations. For example, Guangzhou Jin Ge's duplex container house prices are determined through negotiation based on order volume, while three-story duplex residential mansions in Chongming District, Shanghai, range from 1.06 million to 1.08 million yuan. Additionally, many manufacturers offer customization services, allowing adjustments to dimensions, layouts, and functional partitions according to customer needs.
