Frequently Asked Questions
Q
What steel material is used for the main frame, and why is it hot-dip galvanized?
A
The main frame is made from Q235B Galvanized Steel treated with a hot-dip galvanizing process. This provides superior corrosion resistance compared to standard paint or spray coatings, ensuring long-term structural durability even in harsh outdoor environments.
Q
What is the difference between the 75mm and 50mm sandwich panels used in this structure?
A
The 75mm sandwich panels are used for exterior walls where greater thermal insulation and weather resistance are required. The 50mm panels are applied to the roof and internal partitions, balancing insulation performance with structural weight. Both use dual-sided 0.426mm color-coated steel with a core density of 40 kg/m³.
Q
Can the electrical system be customized to meet local safety standards in my country?
A
Yes. All sockets and wiring can be configured to comply with UL (North America), CE (Europe), or SAA (Australia) standards. The system includes a high-standard 2P 63A main circuit breaker and six Three-proof LED ceiling lights as standard, with further customization available on request.
Q
Are sizes beyond standard 20ft and 40ft container dimensions available?
A
Absolutely. While standard 20ft and 40ft models are the most common configurations, our engineering team can produce units with fully custom lengths, widths, and heights to match specific project site requirements or architectural drawings.
Q
What exterior finish and color options are available for the container house?
A
The exterior surface can be finished in any color from the RAL Color System, and multiple textures are available including Wood Grain, Marble, and Industrial Metal. This allows the unit to blend seamlessly into residential, commercial, or industrial settings.
Q
Can the internal layout be modified to suit my specific floor plan?
A
Yes. The layout offers 100% flexibility. Our engineering team can adjust internal partition walls, door positions, and window placements according to your submitted floor plans or design drawings. Simply provide your requirements and our team will develop a tailored solution.
