Kongdian Container House

Kongdian container houses can be customized or purchased from professional manufacturers according to specific needs, with a focus on structural type, functional purpose, material technology, and compliance qualifications. The following provides an explanation from three aspects: classification, technical key points, and purchasing suggestions.

I. Classification Methods of Container Houses

1. By Structural Source and Construction Method

   • Custom Fixed Box Modules: Newly built according to ISO modulus, using reduced-thickness plates or material substitutions, with non-standard corner fittings arrangements. Highly factory-oriented, suitable for long-term fixed scenarios.
   • Variable Box Modules: Wall panels can be flipped, extended, or rotated (e.g., expandable shops, display boxes), mostly used as single-layer standalone units, offering high flexibility.
   • By Forming Process: Divided into fully welded (dry box type), light steel frame, plug-in, folding, and fixed types. Different processes affect the strength, transportation convenience, and installation efficiency of the houses.

2. By Functional Purpose

   • Accommodation Type: Construction site dormitories, homestays, hotels, etc., requiring attention to thermal insulation, sound insulation, and ventilation design.
   • Office Type: Construction site offices, commercial buildings, etc., emphasizing space utilization and interior decoration.
   • Special Type: Medical boxes, equipment boxes, explosion-proof/refrigerated boxes, etc., needing to meet specific industry standards.

II. Technical Key Points of Container Houses

1. Structural Load-Bearing and Construction

   • Pure steel frame bears the load, with wall panels, roof panels, and glass not bearing weight. The force path is "panel secondary beam → main beam → corner column → corner fitting → foundation/lower box", with corner fittings being the only stacking force transmission points, and spot welding substitution is prohibited.
   • Steel materials must comply with standards: welding weathering steel for the box body (GB/T 4171), and Q235B/Q345B for non-box body components (GB/T 700, GB/T 1591).

2. Fire Protection and Corrosion Resistance

   • Enclosure filling prohibits the use of flammable core materials such as EPS. For crowded places, A-grade rock wool/glass wool is required, with fire resistance limits controlled according to GB50016 (common requirement ≥ 0.5 hours).

III. Purchasing Suggestions

1. Clarify Needs: Determine the functional type based on the usage scenario (e.g., construction site dormitories, commercial offices), and select materials (steel, aluminum alloy, or composite sandwich panels) and mobility (fixed, towable mobile, or folding transportable) according to the budget.
2. Verify Qualifications: Prioritize manufacturers with quality system certifications (e.g., ISO9001), environmental system certifications (ISO14001), and occupational health and safety management system certifications (ISO45001) to ensure product compliance.
3. Inspect Process: Pay attention to welding processes, corrosion protection treatments, and thermal insulation performance to avoid safety hazards caused by inferior steel materials or non-standard thermal insulation cotton.
4. Service Guarantee: Choose manufacturers that provide "one-stop" services including design, production, transportation, and installation, and confirm after-sales maintenance terms (e.g., warranty period, maintenance response time).
