Frequently Asked Questions
Q
What steel grade is used for the main structural frame, and why is hot-dip galvanizing important?
A
The main frame is constructed from high-strength Q235B Galvanized Steel with hot-dip galvanizing treatment. This process coats the steel with a thick zinc layer that provides superior corrosion resistance compared to standard painted or electroplated finishes, significantly extending the structural lifespan — especially in humid, coastal, or harsh outdoor environments.
Q
What is the difference between the 75mm and 50mm sandwich panels, and where is each used?
A
The 75mm sandwich panels are used for exterior walls, providing greater thermal insulation and weather resistance where exposure to external temperatures is highest. The 50mm sandwich panels are applied to the roof and internal partitions, where a thinner profile is sufficient. Both panels feature dual-sided 0.426mm color-coated steel and a high-performance insulation core at 40kg/m³.
Q
Can the electrical system be adapted to meet local standards in different countries?
A
Yes. The electrical sockets and wiring layout are fully customizable to comply with UL (North America), CE (Europe), or SAA (Australia) standards, among others. The system is built around a robust 2P 63A Main Circuit Breaker and includes six high-efficiency Three-proof LED ceiling lights as standard, with further customization available on request.
Q
Is it possible to customize the internal layout, including partition walls, doors, and windows?
A
Absolutely. The design offers 100% flexible layout customization. The engineering team can adjust internal partition positions, door placements, and window configurations based on your provided floor plans or technical drawings, making each unit adaptable to a wide variety of use cases including offices, accommodation, retail, and site facilities.
Q
Are sizes limited to standard 20ft and 40ft container dimensions?
A
No. While standard 20ft and 40ft models are available as a baseline, custom dimensions — including non-standard lengths, widths, and heights — can be manufactured to meet specific project requirements. This flexibility makes the units suitable for unique site footprints or specialized building configurations.
Q
What exterior finish and color options are available for the modular building?
A
A wide range of aesthetic options is available through the RAL Color System, allowing you to specify virtually any standard color for the exterior panels. In addition to solid colors, textured finishes such as Wood Grain, Marble, and Industrial Metal are offered, enabling the structure to blend seamlessly with its surrounding environment or match a specific brand identity.
