💬 Frequently Asked Questions
What steel grade is used in the main frame, and why does it matter?
The main frame is constructed with high-strength Q235B Galvanized Steel that undergoes hot-dip galvanizing treatment. This combination provides exceptional corrosion resistance and structural integrity, ensuring the building performs reliably in harsh outdoor environments and has a long service lifespan.
What is the difference between the 75mm and 50mm sandwich panels?
The 75mm sandwich panels are used for exterior walls where greater thermal and acoustic insulation is required to withstand outdoor temperature variations. The 50mm panels are applied to the roof and internal partitions, offering a balance between insulation performance and weight efficiency. Both feature dual-sided 0.426mm color-coated steel skins.
Can the electrical system be adapted for use in different countries?
Yes. The electrical configuration is fully customizable to comply with international safety standards. Sockets, circuit breakers, and wiring can be tailored to meet UL (North America), CE (Europe), or SAA (Australia) certification requirements, depending on your deployment region.
Is it possible to order a custom size beyond the standard 20ft or 40ft models?
Absolutely. While standard 20ft and 40ft container-style modules are the most common configurations, our engineering team fully supports custom dimensions — including non-standard lengths, widths, and heights — to accommodate unique site conditions or project specifications.
What exterior finish and color options are available?
A wide range of exterior aesthetics can be selected through the RAL color system, giving you precise control over the building's appearance. In addition to solid colors, surface texture options include Wood Grain, Marble, and Industrial Metal finishes to suit both functional and architectural design requirements.
How flexible is the internal layout customization?
The internal layout is 100% flexible. Our engineering team works directly from your floor plans and drawings to customize partition walls, door positions, window placements, and functional zones. Whether you need open-plan spaces, multi-room configurations, or specific workflow layouts, the design can be engineered to your exact requirements.
