Frequently Asked Questions
What type of steel is used in the main frame, and why is it hot-dip galvanized?
The main frame is constructed from high-strength Q235B Galvanized Steel that undergoes a hot-dip galvanizing treatment. This process applies a thick, metallurgically bonded zinc coating that provides superior corrosion resistance compared to spray-on alternatives, ensuring a much longer structural lifespan — especially in humid, coastal, or outdoor environments.
What is the difference between the 75mm and 50mm sandwich panels used in this unit?
The 75mm sandwich panels are used on exterior walls where maximum thermal insulation and weather resistance are required. The 50mm panels are applied to the roof and internal partitions, where a balance between insulation performance and weight reduction is preferred. Both use dual-sided 0.426mm color-coated steel with a core density of 40kg/m³.
Can the electrical system be adapted to meet different international standards?
Yes. The wiring, sockets, and fittings can be fully customized to comply with UL (North America), CE (Europe), or SAA (Australia) certification standards. The unit comes standard with a 2P 63A main circuit breaker and 6x Three-proof LED ceiling lights, all of which can be adjusted to match local electrical codes and voltage requirements.
Is it possible to customize the dimensions beyond the standard 20ft and 40ft sizes?
Absolutely. While 20ft and 40ft are the most common standard configurations, our engineering team offers fully adjustable dimensions — including custom lengths, widths, and ceiling heights — to match the specific spatial requirements of your project. Simply share your floor plan or technical drawings, and we will provide a tailored solution.
What exterior finish and color options are available for the outer panels?
The exterior surface finish can be customized using the RAL color system, giving you access to a wide range of professional colors. In addition to standard solid colors, we offer decorative textures including Wood Grain, Marble, and Industrial Metal finishes — making it easy to match your project's architectural or branding requirements.
How durable and safe is the flooring system in these modular units?
The main floor uses 15mm Cement Fiber Board, which is both fireproof and moisture-resistant — making it suitable for a wide range of environments including construction sites, temporary offices, and storage facilities. The lateral floor is reinforced with 18mm Industrial Grade Construction Form-work, providing additional load-bearing strength and stability for heavy-duty use.
