Frequently Asked Questions
1
What steel grade is used for the main frame, and why does it matter?
The main frame is built with Q235B Galvanized Steel using a hot-dip galvanizing process. This grade offers an excellent balance of tensile strength and weldability, while the hot-dip treatment provides long-term corrosion resistance — making the structure suitable for harsh outdoor environments and extended service life.
2
What is the difference between the 75mm and 50mm sandwich panels?
The 75mm sandwich panel is used on exterior walls where superior thermal insulation and structural rigidity are required. The 50mm panel is applied to the roof and internal partitions, providing adequate insulation at a lighter weight. Both panels feature dual-sided 0.426mm color-coated steel with a 40kg/m³ high-performance insulation core.
3
Can the electrical system be adapted for different countries' standards?
Yes. The electrical system is fully customizable. Sockets, wiring configurations, and safety components can be adapted to comply with UL (North America), CE (Europe), or SAA (Australia) standards, depending on your project's destination country and local regulatory requirements.
4
Are sizes limited to standard 20ft and 40ft container dimensions?
Not at all. While standard 20ft and 40ft models are available, our engineering team offers fully custom dimensions — including non-standard lengths, widths, and heights — to match your specific site conditions and project layout requirements.
5
What exterior finish and color options are available?
A wide range of exterior aesthetics are available through the RAL color system, allowing precise color matching. Texture options include Wood Grain, Marble, and Industrial Metal finishes, enabling the units to blend with diverse architectural environments or meet branding requirements.
6
Is it possible to modify the internal layout after placing an order?
We strongly recommend finalizing your layout before production begins. However, our engineering team supports 100% flexible layout customization during the design phase — including partition placement, door positions, and window configurations — based on your floor plans or architectural drawings submitted prior to manufacturing.
