Frequently Asked Questions
Q
What steel standard is used for the main frame, and why does it matter?
The main frame is fabricated from Q235B Galvanized Steel with hot-dip galvanizing treatment. Q235B offers a reliable balance of tensile strength, weldability, and corrosion resistance, making it ideal for modular structures exposed to varying climates. The hot-dip process ensures the zinc coating penetrates uniformly, providing long-term rust protection compared to electro-galvanizing.
Q
What is the difference between the 75mm and 50mm sandwich panels?
The 75mm sandwich panels are used on exterior walls where superior thermal insulation and structural rigidity are required. The 50mm panels are applied on roofs and internal partitions, providing a lighter weight solution while still meeting thermal and acoustic performance standards. Both use dual-sided 0.426mm color-coated steel facing with a 40kg/m³ core density.
Q
Can the electrical system be adapted for use in different countries?
Yes. The electrical system — including sockets, wiring, and circuit configurations — can be customized to comply with UL (North America), CE (Europe), or SAA (Australia/New Zealand) standards. This ensures your modular building meets local safety codes and can be commissioned without additional re-wiring on-site.
Q
Are sizes limited to standard 20ft and 40ft container dimensions?
Not at all. While 20ft and 40ft are the most common standard sizes, our engineering team offers fully adjustable dimensions — custom lengths, widths, and heights — tailored to your specific project site and spatial requirements. This flexibility is especially useful for multi-unit complexes or irregularly shaped plots.
Q
What exterior finish and color options are available?
Exterior finishes follow the RAL Color System, giving you access to thousands of standardized colors. In addition to solid colors, decorative texture options include Wood Grain, Marble, and Industrial Metal finishes — enabling the building to blend seamlessly into residential, commercial, or industrial environments.
Q
Is the floor system suitable for heavy-duty or industrial use?
The flooring system is designed with two layers: a 15mm Cement Fiber Board as the main floor — which is both fireproof and moisture-resistant — and an 18mm Industrial Grade Construction Form-work for the lateral floor. Together, they provide a robust, load-bearing surface capable of handling commercial and light industrial applications without warping or degradation over time.
