💬 Frequently Asked Questions
What steel grade is used for the main frame, and why does it matter?
The main frame is fabricated from Q235B hot-dip galvanized steel, a high-strength structural grade widely recognized for its excellent weldability and corrosion resistance. The hot-dip galvanizing process provides a thick, durable zinc coating that protects the structure in harsh outdoor environments for decades.
What is the difference between the 75mm and 50mm sandwich panels?
The 75mm sandwich panels are used for exterior walls where superior thermal insulation and weather resistance are required. The 50mm panels are applied to the roof and internal partitions, balancing weight reduction with adequate insulation performance. Both feature dual-sided 0.426mm color-coated steel skins.
Can the electrical system be adapted for use in different countries?
Yes. All sockets, wiring configurations, and circuit components can be customized to comply with UL (North America), CE (Europe), or SAA (Australia) standards, ensuring full compliance with local electrical regulations wherever the unit is deployed.
Are sizes limited to standard 20ft and 40ft container dimensions?
Not at all. While 20ft and 40ft are the most common standard models, our engineering team offers fully adjustable dimensions — custom lengths, widths, and heights — to suit your specific site conditions and project requirements.
What exterior finish and color options are available?
A wide range of exterior finishes is available through the RAL color system, covering thousands of standardized colors. Texture options include Wood Grain, Marble, and Industrial Metal finishes, allowing the units to blend seamlessly into various architectural environments.
How fire-resistant and moisture-resistant is the flooring system?
The main floor uses 15mm Cement Fiber Board, which is specifically engineered for fireproof and moisture-resistant performance, making it suitable for demanding construction and industrial site conditions. The lateral floor uses 18mm industrial-grade construction formwork for additional load-bearing support.
