Frequently Asked Questions
Q
What type of steel is used for the main frame, and why is it hot-dip galvanized?
The main frame is fabricated from Q235B Galvanized Steel and treated with a hot-dip galvanizing process. This method provides superior corrosion resistance compared to spray-on coatings — the zinc layer bonds metallurgically with the steel surface, ensuring long-term structural durability even in harsh outdoor or humid environments.
Q
What is the difference between the 75mm and 50mm sandwich panels?
The 75mm sandwich panels are used for exterior walls, providing enhanced thermal insulation against outside temperature fluctuations. The 50mm sandwich panels are applied to the roof and internal partitions where a balance between insulation performance and structural weight is required. Both feature dual-sided 0.426mm color-coated steel for durability and aesthetics.
Q
Can the electrical system be configured to meet different international standards?
Yes. The electrical system — including sockets, wiring layout, and circuit protection — can be fully customized to comply with UL (North America), CE (Europe), or SAA (Australia) standards. Please specify your target market requirements at the time of ordering so our engineering team can prepare the appropriate configuration.
Q
Are sizes limited to standard 20ft and 40ft container dimensions?
Not at all. While we offer standard 20ft and 40ft models as ready-to-produce baselines, custom lengths, widths, and heights are fully available. Our engineering team works directly with your project drawings to produce units that fit your site layout and operational needs precisely.
Q
What exterior finishes and colors are available for the surface of the cabin?
We support the full RAL color system for exterior panels, allowing precise color matching to project or brand requirements. In addition, textured finishes including Wood Grain, Marble, and Industrial Metal effects are available to achieve both contemporary and functional aesthetics.
Q
Is the flooring suitable for heavy-duty industrial or commercial use?
Yes. The main floor uses 15mm Cement Fiber Board which is both fireproof and moisture-resistant — ideal for wet or high-traffic environments. The lateral floor incorporates 18mm Industrial Grade Construction Form-work, providing additional load-bearing capacity suited for commercial, industrial, and site-office applications.
