Frequently Asked Questions
Q
What type of steel is used in the main frame and why is it hot-dip galvanized?
The main frame is constructed from high-strength Q235B steel, a widely recognized structural carbon steel grade. Hot-dip galvanizing provides a thick, metallurgically bonded zinc coating that offers superior corrosion resistance compared to electro-galvanizing, making it ideal for long-term outdoor and industrial deployments.
Q
What is the difference between the 75mm and 50mm sandwich panels?
The 75mm sandwich panel is used on exterior walls where greater thermal insulation and structural rigidity are required. The 50mm sandwich panel is applied to roofs and internal partitions, balancing weight reduction with adequate insulation performance. Both use dual-sided 0.426mm color-coated steel facings with a 40 kg/m³ core density.
Q
Can the electrical system be adapted for different international standards?
Yes. The electrical wiring, sockets, and fittings can be fully customized to comply with UL (North America), CE (Europe), or SAA (Australia) standards, depending on your deployment region. The main circuit breaker is rated at 2P 63A to support standard commercial loads.
Q
Are custom sizes available beyond the standard 20ft and 40ft container office dimensions?
Absolutely. While 20ft and 40ft are the most common standard configurations, our engineering team offers fully adjustable dimensions — including custom lengths, widths, and floor-to-ceiling heights — to precisely match your project's spatial and functional requirements.
Q
What exterior finish and color options are available?
Exterior finishes can be specified using the RAL color system for precise color matching. Texture options include Wood Grain, Marble, and Industrial Metal, allowing the unit to blend into residential, commercial, or industrial environments as needed.
Q
How durable is the flooring system and is it suitable for heavy-duty use?
The main floor uses a 15mm Cement Fiber Board that is both fireproof and moisture-resistant, making it highly durable for daily commercial use. The lateral floor uses 18mm industrial-grade construction formwork, engineered to withstand substantial loads and high foot traffic typical in worksite or office environments.
