Container Mobile House Materials

The main materials for container mobile houses include structural steel, wall panel materials, flooring materials, and auxiliary accessories, as detailed below:

Structural Steel

The core load-bearing structure of container mobile houses typically uses hot-dip galvanized cold-formed steel. This type of steel is shaped through cold-forming processes, and its surface galvanization effectively prevents rust, extending its service life. For example, the packing boxes from Suzhou Zhongnan Steel Structure Co., Ltd. feature a fully steel structural frame, with measured wind resistance up to Level 12 and earthquake resistance up to Level 8. The frame deformation rate is only 0.18%, well below the industry's acceptable threshold of 0.3%, demonstrating the strength and stability of hot-dip galvanized cold-formed steel.

Wall Panel Materials

Wall panels need to balance thermal insulation, sound insulation, and fire resistance. Common materials include:

• Rock wool/glass wool sandwich panels: These panels use rock wool or glass wool as the core material, covered with metal sheets or calcium silicate boards. They offer excellent fire resistance (up to Class A fire rating) and thermal insulation, suitable for long-term use.
• Polyurethane sandwich panels: These panels use polyurethane foam as the core material, providing superior thermal insulation. However, their fire resistance rating needs to be enhanced with flame retardants and is mostly used in temporary buildings with high thermal insulation requirements.

Flooring Materials

Flooring needs to meet load-bearing and wear-resistant requirements. Common materials include:

• Cement fiber boards: These boards offer high strength, moisture resistance, and corrosion resistance, suitable for heavy-duty scenarios.
• Steel-wood composite flooring: Combining the advantages of steel and wood, this flooring ensures load-bearing capacity while enhancing comfort, often used in high-end cultural tourism homestays or office spaces.

Auxiliary Accessories

• Door and window systems: These mostly use aluminum alloy or plastic-steel materials, paired with tempered glass to enhance lighting and safety. For example, integrated light steel villa movable houses are equipped with high-strength tempered glass windows for long-term use.
• Electrical and plumbing systems: These are embedded in walls or floors and require waterproof, corrosion-resistant pipes and cables to ensure safety.
• Connectors: Such as screws and corner pieces, need to have high strength and corrosion resistance to ensure structural stability. For example, the galvanized thickened frame assembly screws in container house frame accessories allow assembly without welding, improving installation efficiency.
