Dalian Export Container Modular Houses

The container modular houses exported from Dalian are movable building units transformed from standard containers as basic modules. They feature modularity, customizability, and rapid deployment, and are widely used in temporary building scenarios.

I. Basic Definitions and Production Process

Container modular houses in Dalian are made from retired shipping containers as raw materials, achieving functional upgrades through systematic transformation. The production process includes four core steps:

1. Screening and Reinforcement: Conduct structural integrity tests on recycled containers, select those that meet standards, and enhance load-bearing capacity through welding reinforcement bars and adding crossbeams to ensure compliance with building safety regulations.
2. Surface Treatment: Employ sandblasting for rust removal, apply anti-rust primer and topcoat painting processes to improve corrosion resistance, and adjust appearance colors or materials (such as adding insulation layers or decorative panels) according to design requirements.
3. Opening Cutting: Cut openings for doors, windows, and ventilation based on functional needs, and install reinforcing frames to maintain structural stability. For example, when creating large glass windows on the side of a container, steel frames must be added.
4. Interior Finishing: Complete pre-installation of water and electricity lines, wall and floor treatments (such as laying PVC flooring and installing integrated ceilings), and basic furniture installation (such as simple partitions and lighting systems) in the factory. Some high-end products can integrate air conditioning and bathroom facilities.

II. Local Suppliers and Business Models

Dalian boasts a mature container house industry chain, with representative companies including Yunzhu Weilai, Hongyuan, and Hanzhizhu, offering full-service solutions from design to delivery. Additionally, companies like Dalian Jinzhou Shengjie Containers and Dalian Yutongda Container Houses support customized production, short-term leasing, and used container recycling, meeting diverse customer budgets and usage cycles. For instance, tourist attractions can reduce seasonal housing costs through leasing, while construction sites prefer purchasing customized products as long-term project headquarters.

III. Typical Application Scenarios

The deployment scenarios of container modular houses in Dalian heavily rely on their modularity and mobility advantages:

• Construction Sites: Used as project headquarters or worker dormitories, they can be quickly relocated with project progress, reducing repeated setup costs.
• Tourist Attractions: Employed for seasonal operations such as guesthouses, restaurants, or ticket offices, enabling rapid deployment and retrieval through standardized design.
• Temporary Workstations: Such as environmental monitoring stations or power repair stations, integrating specialized equipment to meet specific industry needs.

IV. Customized Design Logic

Customization must balance functional integration and environmental adaptability:

• Physical Space Reconfiguration: Expand usable area by stacking or connecting multiple containers, such as creating dual-level structures for separate office and accommodation zones.
• Envelope System Optimization: Use double-glazed windows, rock wool insulation panels, and other materials to enhance thermal insulation, adapting to northern cold climates.
• Functional Module Integration: Embed smart systems (such as solar power and IoT monitoring) or specialized equipment (such as laboratory ventilation ducts) according to scenario requirements.
