❓ Frequently Asked Questions
🔩
What type of steel is used for the main frame, and why is it galvanized?
The main frame is constructed from high-strength Q235B steel treated with a hot-dip galvanizing process. This treatment applies a thick zinc coating to all surfaces, providing long-term protection against rust, corrosion, and environmental weathering — making it ideal for both indoor and outdoor deployments in demanding conditions.
🧱
What is the difference between the 75mm and 50mm sandwich panels?
The 75mm sandwich panels are used for exterior walls where maximum thermal insulation and structural rigidity are required. The 50mm panels are applied to the roof and internal partitions, balancing insulation performance with reduced structural load. Both use dual-sided 0.426mm color-coated steel with a 40kg/m³ high-performance insulation core.
⚡
Can the electrical system be adapted for different international standards?
Yes. All sockets, wiring configurations, and outlets can be customized to meet UL (North America), CE (Europe), or SAA (Australia) compliance standards, ensuring the unit is ready for use in your specific region without additional modification.
📐
Are custom sizes available beyond the standard 20ft and 40ft container dimensions?
Absolutely. While standard 20ft and 40ft models are available off-the-shelf, our engineering team offers fully adjustable dimensions — including custom lengths, widths, and ceiling heights — to meet the precise requirements of your construction project or site layout.
🎨
What exterior finish and color options are available?
A wide range of surface finishes are available using the RAL color system for precise color matching. Texture options include Wood Grain, Marble, and Industrial Metal finishes, allowing the unit to blend seamlessly with various architectural environments or branding requirements.
🏗️
Can the internal layout be fully redesigned to match my floor plan?
Yes. The modular design supports 100% flexible internal layouts. Our engineering team works directly from your submitted floor plans or drawings to reconfigure partition walls, door positions, window placements, and utility routing — ensuring the final unit perfectly matches your operational needs.
