How About Welding Container Houses

Admin September 17, 2026

Welding container houses offer advantages such as structural stability, practical functionality, and high flexibility, making them suitable for various temporary or semi-permanent scenarios. However, attention must be paid to material quality and construction standards to ensure performance meets requirements.

Structural Design and Technical Principles

Welding container houses use high-strength steel (such as Q345 low-alloy steel) as the main frame, with components connected through full-welding processes to form a closed box structure. Full-welding ensures uniform, seamless welds, significantly enhancing wind and water resistance, enabling the structure to withstand winds of up to 8 levels and heavy rain. The box adopts a composite structure of “steel frame + functional interlayer”: an insulation layer (such as rock wool or polyurethane foam) and soundproofing material are laid inside, while a waterproof coating covers the exterior, providing multiple layers of protection. Modular design allows multiple boxes to be joined with bolts, enabling rapid expansion of living space to meet different scale requirements.

Core Functions and Suitable Scenarios

Their core function is to provide a safe and dry living environment. The steel structure can bear loads of over 2 tons, and the insulation layer maintains indoor temperatures between 10 - 30℃ in ambient temperatures ranging from -10℃ to 40℃, adapting to most climatic conditions. Typical applications include construction site dormitories, field exploration camps, and disaster emergency shelters, especially for projects requiring rapid setup and cost sensitivity. For example, in post-disaster reconstruction, their ability to be lifted and relocated as a whole significantly shortens the shelter setup period.

Usage Advantages and Maintenance Points

Advantages:

  • Durability: The steel structure is resistant to deformation, with a normal service life of over 15 years, far exceeding traditional prefabricated houses.
  • Safety: Full-welding processes and wind-resistant design reduce the risk of collapse, meeting the strength requirements of China's “Technical Specifications for Container-Type Prefabricated Houses” (e.g., weld strength ≥ 80% of the base material).
  • Flexibility: Supports lifting as a whole or disassembly and reassembly, adapting to site changes.

Maintenance:

  • Regularly inspect weld integrity and clean drainage channels to prevent water accumulation.
  • Replace aging seals to ensure waterproof performance.
  • Maintenance is simple and does not require specialized equipment.

Technical Standards and Material Selection

High-quality welding container houses must meet the following standards:

  • Box wall thickness ≥ 2mm to ensure structural strength.
  • Insulation layer thermal conductivity ≤ 0.03W/(m·K), with priority given to Class A fire-resistant materials (such as rock wool).
  • Waterproof design uses a dual approach of “structural self-waterproofing + sealing strips” to prevent leakage.
    In terms of materials, Q345 low-alloy steel is more suitable for high-load scenarios due to its 30% higher yield strength compared to ordinary carbon steel.
