Frequently Asked Questions
What steel grade is used for the main frame, and why is hot-dip galvanizing important?
The main frame uses high-strength Q235B steel with hot-dip galvanization treatment. This process creates a thick, bonded zinc coating that provides superior corrosion resistance compared to electro-galvanizing, significantly extending the structural lifespan of the building — especially in humid or coastal environments.
What is the difference between the 75mm and 50mm sandwich panels used in this building?
The 75mm sandwich panels are used for exterior walls, offering greater thermal insulation and weather resistance. The 50mm panels are applied to the roof and internal partitions where structural load and thermal requirements are slightly lower. Both use dual-sided 0.426mm color-coated steel with a 40 kg/m³ core density for high performance.
Can the electrical system be configured to comply with different country standards?
Yes. The electrical sockets and wiring can be fully customized to comply with UL (North America), CE (Europe), or SAA (Australia) standards. This makes the unit suitable for deployment across multiple international markets without requiring rewiring on-site.
What customization options are available for dimensions beyond standard 20ft and 40ft sizes?
Beyond the standard 20ft and 40ft container models, our engineering team can produce units with custom lengths, widths, and heights to suit your specific project site or functional requirements. Custom dimensions are assessed on a per-project basis, and detailed drawings or floor plans are welcomed to facilitate the design process.
What exterior finish options are available, and how durable are they?
Exterior finishes can be selected from the RAL color system, offering a wide range of standard and custom colors. Texture options include Wood Grain, Marble, and Industrial Metal finishes. These surface coatings are applied to color-coated steel panels that are resistant to UV fading, scratching, and moisture, ensuring long-term aesthetic and structural performance.
Is the flooring system suitable for heavy industrial or commercial use?
Yes. The main floor uses 15mm Cement Fiber Board, which is both fireproof and moisture-resistant, making it suitable for office, commercial, and light industrial applications. The lateral floor uses 18mm Industrial Grade Construction Form-work, providing additional load-bearing capacity and structural rigidity for heavier usage scenarios.
