Frequently Asked Questions
What steel standard is used for the main frame, and why does it matter?
The main frame is made from Q235B Galvanized Steel with hot-dip galvanizing treatment. Q235B is a structural carbon steel known for high tensile strength and excellent weldability. The hot-dip galvanizing provides a thick zinc coating that protects against rust and corrosion, ensuring long-term durability even in harsh outdoor environments.
What is the difference between the 75mm and 50mm sandwich panels used in this structure?
The 75mm sandwich panels are used for exterior walls, providing superior thermal and acoustic insulation for the building envelope. The 50mm panels are applied to the roof and internal partitions where moderate insulation performance is sufficient. Both use dual-sided 0.426mm color-coated steel and a 40kg/m³ core density for consistent quality.
Can the electrical system be adapted for different countries and certification standards?
Yes. The sockets, wiring layout, and components can be fully customized to comply with UL (United States), CE (Europe), or SAA (Australia) standards. The system also includes a heavy-duty 2P 63A Main Circuit Breaker for safe and reliable power management. Please specify your target country during the order process.
Is it possible to get a custom size beyond the standard 20ft or 40ft container dimensions?
Absolutely. While standard 20ft and 40ft models cover most use cases, our engineering team can produce units with custom lengths, widths, and heights to meet your exact project requirements. Simply provide your target dimensions and intended use, and we will prepare a tailored technical proposal for your review.
What exterior finish and color options are available for the container building?
A wide range of aesthetic options is available using the RAL color system, ensuring precise and consistent color matching. Surface textures include Wood Grain, Marble, and Industrial Metal finishes. These options allow the building to blend naturally into residential, commercial, or industrial environments according to your design preferences.
How durable and safe is the flooring system in these modular buildings?
The main floor uses a 15mm Cement Fiber Board, which is both fireproof and moisture-resistant — making it ideal for high-humidity or safety-critical environments. The lateral floor is supported by 18mm Industrial Grade Construction Formwork, providing a robust and stable base. Together, these materials ensure a long-lasting, load-bearing floor system suitable for heavy daily use.
