Container House Wall

The walls of container houses typically use color-steel sandwich panels, metal panels, calcium silicate boards, or decorative materials, depending on design requirements and functional positioning.

1. Basic Structure and Materials
   The main body of container house walls originates from the steel structural framework of freight containers, with a core of standardized hot-dip galvanized cold-formed steel sections that offer pressure resistance, wind resistance, and corrosion resistance. Walls usually adopt a prefabricated modular design, with common materials being color-steel sandwich panels filled with insulation materials such as rock wool, glass wool, or polyurethane, balancing lightweight properties with thermal insulation. For example, packing-box container houses use hot-dip galvanized cold-formed steel sections as the framework, paired with fire-resistant polyurethane sandwich panels to achieve thermal insulation, heat resistance, and fire protection functions.

2. Surface Treatment and Decoration
   To enhance aesthetics and practicality, wall surfaces undergo diverse treatments. For example:

   • Metal panels or calcium silicate boards: Used directly as interior and exterior wall cladding materials, providing a flat and durable surface suitable for scenarios requiring a minimalist style.
   • Decorative coatings or claddings: Some designs retain the corrugated metal texture of containers or enhance visual effects through black glossy paint applications or wood veneer installations. For instance, a container house in Denmark retains the corrugated metal on interior walls while introducing natural light through large windows, creating a blend of industrial style and warmth.

3. Application of Functional Materials
   Wall materials are optimized based on usage scenarios:

   • Fire resistance: Wall panels often use rock wool or polyurethane sandwich panels to meet basic fire safety requirements, with some products complying with national building codes.
   • Waterproofing and moisture resistance: Exterior walls employ structural sealing designs (e.g., welded joint treatments) and waterproof coatings to ensure long-term use in humid environments.
   • Sound insulation: Insulation materials within sandwich panels effectively block noise, making them suitable for residential or office settings.

4. Customized and Artistic Design
   Modern container architecture emphasizes personalized expression, with walls achieving differentiation through the following methods:

   • Window openings and lighting: Large glass windows or skylight designs break the enclosed feel of containers while improving indoor lighting.
   • Modular combinations: The拼接 (splicing) and staggered layout of multiple containers create unique wall textures and spatial hierarchies.
