Frequently Asked Questions
What steel grade is used for the main frame, and why does it matter?
The main frame is constructed from Q235B Galvanized Steel with hot-dip galvanizing treatment. This grade offers excellent tensile strength and resistance to corrosion, ensuring the structure remains stable and durable across a wide range of climates and site conditions over the long term.
What is the difference between the 75mm and 50mm sandwich panels?
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 interior partitions, balancing weight reduction with adequate insulation performance. Both use dual-sided 0.426mm color-coated steel for a consistent, professional finish.
Is the flooring suitable for heavy-duty industrial or commercial use?
Yes. The main floor uses a 15mm Cement Fiber Board which is both fireproof and moisture-resistant, making it ideal for demanding environments. The lateral floor uses 18mm Industrial Grade Construction Form-work, engineered to withstand significant load-bearing requirements in commercial and industrial applications.
Can the electrical system be adapted for use in different countries?
Absolutely. All sockets and internal wiring can be fully customized to comply with UL (USA), CE (Europe), and SAA (Australia) standards. The system also features a high-standard 2P 63A main circuit breaker and energy-efficient three-proof LED lighting to meet diverse international project requirements.
How flexible are the customization options for layout and dimensions?
Customization is 100% flexible. The engineering team is able to adjust internal partition layouts, door and window positions based on client-provided floor plans. In addition to standard 20ft and 40ft container sizes, fully custom lengths, widths, and heights can be manufactured to match any specific project requirement.
What exterior finish and color options are available?
Multiple exterior finishes are available through the RAL color system, allowing precise color matching for any branding or architectural requirement. Surface texture options include Wood Grain, Marble, and Industrial Metal finishes, providing a wide range of aesthetic choices suitable for residential, commercial, and industrial projects.
