Frequently Asked Questions
Q
What type of steel is used for the main frame, and why is hot-dip galvanizing important?
The main frame is constructed from high-strength Q235B Galvanized Steel treated via a hot-dip galvanizing process. This method creates a thick, metallurgically bonded zinc coating that provides superior corrosion resistance compared to spray or electroplating methods — ensuring long-term structural integrity even in humid, coastal, or harsh outdoor environments.
Q
What is the difference between the 75mm and 50mm sandwich panels used in this building?
The 75mm sandwich panels are applied to exterior walls where greater thermal insulation and weather resistance are required. The 50mm sandwich panels are used for roofing and internal partitions, offering a balanced combination of insulation performance and structural weight. Both panels feature dual-sided 0.426mm color-coated steel and a high-density 40kg/m³ core.
Q
Can the electrical system be configured to meet different international standards?
Yes. All sockets and internal wiring can be customized to comply with UL (North America), CE (Europe), or SAA (Australia) standards, depending on your destination country and project requirements. The main circuit breaker is a high-standard 2P 63A unit suitable for most commercial and site-office applications.
Q
Is the floor system suitable for heavy-duty industrial use?
The main flooring uses a 15mm Cement Fiber Board, which is both fireproof and moisture-resistant — ideal for office, dormitory, or light commercial use. For heavier load requirements, the lateral floor utilizes 18mm Industrial Grade Construction Form-work, providing enhanced load-bearing capacity for site offices, workshops, or storage applications.
Q
Are custom sizes available beyond the standard 20ft and 40ft container dimensions?
Absolutely. While standard 20ft and 40ft models are available for quick deployment, our engineering team can design and fabricate units with fully custom lengths, widths, and heights to match your exact project footprint, site constraints, or architectural drawings.
Q
What exterior finish and color options are available for the modular building?
A wide range of exterior finishes is available through the RAL Color System, allowing precise color matching for branding or site requirements. Texture options include Wood Grain for a natural aesthetic, Marble for an upscale appearance, and Industrial Metal for a modern, utilitarian look — all applied to the sandwich panel surface without compromising insulation performance.
