Frequently Asked Questions
Q1
What type of steel is used for the main frame, and why is it galvanized?
The main frame is constructed from high-strength Q235B Galvanized Steel using a hot-dip galvanizing process. This treatment provides superior corrosion resistance compared to standard painted steel, significantly extending the structural lifespan — especially in humid, coastal, or outdoor environments.
Q2
What is the difference between the 75mm and 50mm sandwich panels used in this structure?
The 75mm sandwich panels are applied to exterior walls where greater thermal insulation and weather resistance are required. The 50mm panels are used for the roof and internal partitions, balancing insulation performance with weight efficiency. Both use dual-sided 0.426mm color-coated steel for durability.
Q3
Can the electrical system be adapted for different countries and compliance standards?
Yes. The electrical wiring, sockets, and components can be fully customized to meet UL (USA), CE (Europe), or SAA (Australia) certification standards. Please specify your target market requirements at the time of order to ensure full compliance.
Q4
Is it possible to customize the size beyond the standard 20ft and 40ft container dimensions?
Absolutely. Beyond standard 20ft and 40ft models, our engineering team offers fully adjustable custom lengths, widths, and heights tailored to your specific project or site requirements. Simply provide your floor plan or dimensions and we will prepare a bespoke solution.
Q5
What exterior finish and color options are available for the modular cabin?
A wide range of exterior finishes is available through the RAL Color System, ensuring consistent and professional color matching. Texture options include Wood Grain, Marble, and Industrial Metal finishes — suitable for residential, commercial, or industrial applications.
Q6
Is the flooring fireproof and moisture-resistant? What materials are used?
Yes. The main floor uses a 15mm Cement Fiber Board, which is both fireproof and moisture-resistant — making it suitable for long-term use in various climates. The lateral floor uses 18mm Industrial Grade Construction Form-work, providing additional structural support and load-bearing capacity.
