Container House Installation and Production
The installation and production of container houses should follow standardized processes, integrating modular design with on-site assembly techniques, and emphasizing material selection, structural stability, and compliance to meet the needs of different scenarios.
1. Core Processes and Production Workflow
The manufacturing of container houses is primarily factory-prefabricated, with core processes including steel frame welding, composite processing of wall and roof panels, and pre-embedding of internal systems. The frames are mostly made of hot-dip galvanized cold-formed steel, which is automatically cut and welded to form load-bearing structures, providing rust and corrosion resistance after surface treatment. Wall and roof panels are filled with rock wool, glass wool, or polyurethane sandwich panels, balancing insulation and fire resistance. The production workflow covers design deepening, steel processing, wall panel compositing, system pre-installation, and trial assembly to ensure component precision and compatibility. For example, China Construction Steel Structure completes over 80% of the processes in the factory, including the main structure, interior decoration, and mechanical and electrical piping layout, with only module assembly and utility connections required on-site, significantly shortening the construction period.
2. Modular Design and On-Site Installation
Modularity is a core advantage of container houses. The houses are disassembled into independent spatial units (such as room modules), which are assembled using high-strength bolts or welding, supporting multi-story stacking and flexible layouts. Taking the three-story office building by COSCO Shipping Qidong Container Factory as an example, 96 specially made container units were precisely assembled, with the container manufacturing taking 6 days and on-site assembly only 5 days, reducing the overall construction period by 60%-70% compared to traditional buildings. On-site installation requires attention to bottom frame leveling (diagonal difference ≤3mm), bolt tightening sequence, and floor laying techniques to ensure structural stability. For example, Boyuan Container House's installation diagram explicitly requires that the top of the π-shaped secondary beams and bottom beams should be fixed with round-head drill tail screws, and the floor joints should be nailed at intervals of 300-350mm along the centerline.
3. Material Selection and Functional Adaptation
Material selection directly affects house performance. Structural steel must meet wind and earthquake resistance requirements, such as modular buildings in the North American market using high-strength bolts to connect foundations, capable of withstanding strong typhoons and earthquakes. Wall panels must have an A-grade fire rating, while flooring materials need to be wear-resistant and moisture-proof. For different scenarios, product types need to be adapted accordingly: construction site temporary buildings should prioritize packing-box container houses (for independent use or stacking); cultural tourism homestays are suitable for light steel frame houses (with flexible customization of appearance and layout); and emergency housing requires functional kiosks (adjustable in size and supporting rapid deployment). Additionally, insulation layers (such as soundproof cotton + thermal insulation cotton) and lightning protection measures (for mountainous and wilderness scenarios) are key to enhancing living comfort and safety.
4. Compliance and Full-Cycle Management
Compliance is a core threshold for cross-border projects. Domestic manufacturers need to obtain CSA W47.1 welding certification, CSA A660 steel structure certification, and CSA A277 modular product certification, covering welding quality, building systems, and the entire product workflow. For example, China Construction Science and Engineering became the first domestic company to obtain all three core Canadian standards, laying the foundation for its expansion into the North American market. In terms of full-cycle management, it is recommended to choose source manufacturers that support customization of irregular sizes, provide free transportation and installation, and after-sales services to reduce disassembly and assembly losses and operational costs. According to industry research, products with multiple reuse capabilities, cross-border compliance qualifications, and low-carbon attributes account for over 60% of orders, becoming the mainstream procurement direction.
