Suzhou Container-Style House Construction

For the construction of container-style houses in Suzhou, it is crucial to focus on material selection, structural design, functional layout, and compliance. Combining standardized and modular construction methods can achieve efficient construction and long-term use.

I. Material Selection and Performance Requirements

The core material for container-style houses is color-coated steel sandwich panels, whose quality directly affects the lifespan of the house. It is essential to select sandwich panels specifically designed for residential containers, such as new polyurethane insulation sandwich panels or high-performance rock wool sandwich panels, avoiding the use of thin steel sheets used in movable panel houses (which are prone to detachment and rust). High-quality color-coated steel sheets should meet the following criteria:

• Durability: The coating treatment has a lifespan of approximately 15 years, and regular application of anti-corrosion coatings can extend it to over 30 years;
• Lightweight: The weight per square meter should be less than 13 kilograms to reduce structural load;
• Thermal Insulation: Utilize rock wool or polyurethane composite panels with low thermal conductivity to adapt to different climatic needs;
• Fire and Water Resistance: Comply with building fire safety regulations, and ensure that joints are sealed to prevent leakage.

II. Structural Design and Construction Key Points

1. Standardized and Modular Design Container houses are based on standard steel chassis, forming building clusters through horizontal connections and vertical stacking. Common dimensions are 6 meters in length, 2.5 meters in width, and 2.8 meters in height, which can be combined into multi-functional spaces such as offices, dormitories, and restrooms.
2. Earthquake Resistance and Stability Adopt a lightweight steel structure framework with overall welding or bolt connections to ensure earthquake resistance and deformation resistance. For example, K-type movable houses can withstand an earthquake intensity of up to magnitude 7, making them suitable for field operations or temporary buildings.
3. Construction Convenience Modular installation allows for quick completion and reduces on-site waste. For instance, the integrated houses produced by Shandong Xinhao Integrated Housing Co., Ltd. achieve factory production and high on-site assembly efficiency.

III. Functional Layout and Customization Needs

1. Basic Layout
   • Single/Double Occupancy Dormitories: Equipped with standard restrooms, doors, and windows, with adjustable positions on-site;
   • Offices: Configured with office desks, lighting fixtures, imported non-slip carpets, and other facilities;
   • Combined Buildings: Form multi-purpose building clusters by connecting multiple containers or adding partitions.
2. Lighting and Thermal Insulation Optimization
   • Install large floor-to-ceiling windows and roof skylights to enhance indoor brightness;
   • Add internal thermal insulation layers to walls and select triple-glazed windows for better winter insulation than brick walls.

IV. Compliance and Post-Construction Maintenance

1. Approval and Land Use
   • For rural homesteads, construction approval is required, and structural drawings must be provided;
   • Leased land is only for temporary use, and the contract must specify the intended use.
2. Rust Prevention and Waterproofing
   • Cut and welded areas should be polished and coated with epoxy primer and topcoat, with regular inspections of welds and corners;
   • Replace sealants every 5-7 years to prevent moisture damage by avoiding direct contact between the container and the ground.
