Container House Wall Thickness Requirements

The wall thickness requirements for container houses vary depending on the product type, purpose, and applicable standards. Common wall thickness ranges from 75mm to 150mm, with some customized products potentially being thicker, depending on specific needs.

I. Wall Thickness Ranges for Common Products

1. Packing-box Container Houses: For example, the products from Erdos Hanjiang have a wall thickness of 75mm, using a steel frame, suitable for temporary construction sites, emergency command centers, etc.
2. Modular Houses/Container Hotels: Products from brands like Yazhi have a wall thickness of up to 150mm, complying with Australian, American, and Chinese standards, mainly used in high-end cultural tourism or commercial projects in Europe and North America.
3. Customized Container Houses: According to the '2026 Tianjin Customized Container House Industry Analysis', temporary construction sites need to meet structural safety requirements. Regular packing-box designs should withstand wind pressure from six floors (about 0.8kN/m²), with wall thickness usually not below the standard value; high-end products like Apple Pods may have increased wall thickness due to irregular steel structures.

II. Relationship Between Wall Thickness and Performance

1. Structural Strength: Wall thickness directly affects wind and earthquake resistance. For example, container house manufacturers in Yancheng recommend a main frame wall thickness of ≥1.5mm, using Q235B or higher Chinese standard carbon steel to ensure the stability of the triangular load-bearing system.
2. Fire and Thermal Insulation: Thick walls combined with fire-retardant materials (such as rock wool, polyurethane) can improve fire ratings. Temporary construction sites need to achieve Class A non-combustibility (oxygen index ≥32), while Apple Pods, due to complex circuitry, require structural and decoration materials to meet Class B1 or higher.
3. Moisture and Water Resistance: Wall thickness works together with sealing techniques. For example, products from Rizhao, Shandong, achieve moisture and water resistance through structural drainage, PVC rainwater pipes, and moisture-proof materials; customized products in Beijing emphasize the weather resistance of sealants to prevent leakage.

III. Purchase Recommendations

1. Verify Standards: Prioritize products that comply with Chinese national standards (e.g., GB/T 8624-2012) or industry norms (e.g., t/szmha 0001-2021) to ensure wall thickness and materials meet requirements.
2. Request Test Reports: Ask manufacturers for factory inspection reports to avoid falsely labeled wall thickness (e.g., a case where a product was labeled as 0.8mm but measured only 0.5mm).
3. Match to Scenarios: For temporary construction sites, standard wall thickness (75-150mm) can be selected; for high-humidity or extreme climate areas, thicker walls combined with anti-corrosion treatment (e.g., salt spray test ≥500 hours) are needed.
