Frequently Asked Questions
Q
What steel grade is used for the main frame, and why does it matter?
The main frame is constructed from Q235B Galvanized Steel treated with a hot-dip galvanizing process. This grade provides excellent tensile strength and corrosion resistance, ensuring the structure remains durable in harsh outdoor environments and over long-term use.
Q
What is the difference between the 75mm and 50mm sandwich panels?
The 75mm sandwich panel is used for exterior walls where maximum thermal insulation and weather resistance are required. The 50mm panel is used for roofs and internal partitions, balancing insulation performance with structural weight. Both use dual-sided 0.426mm color-coated steel and a 40kg/m³ core density.
Q
Can the electrical system be adapted to meet my country's standards?
Yes. All sockets and internal wiring can be customized to comply with UL (North America), CE (Europe), or SAA (Australia) standards. Please specify your target market when placing your order so our team can configure the system accordingly.
Q
Are custom dimensions available beyond the standard 20ft and 40ft sizes?
Absolutely. While standard 20ft and 40ft container office models are available off-the-shelf, our engineering team fully supports custom lengths, widths, and heights. Simply provide your project drawings or dimensional requirements and we will design a solution to match.
Q
What exterior finish and color options are available?
We offer a wide range of exterior finishes using the RAL color system, including smooth solid colors as well as decorative textures such as Wood Grain, Marble, and Industrial Metal. Custom color matching is also available upon request for branding or project-specific requirements.
Q
Is the flooring system fireproof and suitable for heavy use?
Yes. The main floor uses 15mm Cement Fiber Board, which is both fireproof and moisture-resistant, making it ideal for demanding site conditions. The lateral floor uses 18mm Industrial Grade Construction Form-work for additional structural support and load-bearing capacity.
