Frequently Asked Questions
What type of steel is used in 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 a thick, uniform zinc coating that protects against rust and corrosion, significantly extending the structural lifespan even in harsh outdoor or marine environments.
What is the difference between the 75mm and 50mm sandwich panels?
The 75mm sandwich panels are used on exterior walls to provide superior thermal insulation and weather resistance, while the 50mm panels are applied to the roof and internal partitions where slightly less insulation thickness is sufficient. Both panels feature dual-sided 0.426mm color-coated steel for durability and aesthetics.
Can the electrical system be customized to meet different country standards?
Yes. All sockets and internal wiring can be configured to comply with UL (North America), CE (Europe), or SAA (Australia) certification standards, ensuring full compliance with local electrical regulations in your target market or project location.
Are sizes limited to standard 20ft and 40ft container dimensions?
Not at all. While standard 20ft and 40ft models are available as ready configurations, our engineering team supports fully custom dimensions — including adjusted lengths, widths, and heights — to meet the specific spatial requirements of any project or site layout.
What exterior finish and color options are available for the modular cabin?
The exterior surface finish is highly customizable. Customers can choose from a wide range of RAL system colors and multiple texture options including Wood Grain, Marble, or Industrial Metal finishes, allowing the unit to blend seamlessly with its surrounding architecture or brand identity.
How fire-resistant and moisture-resistant is the flooring system?
The main floor uses 15mm Cement Fiber Board, which is specifically rated for both fireproof and moisture-resistant performance, making it suitable for high-humidity and fire-risk environments. The lateral floor incorporates 18mm industrial-grade construction formwork for additional structural strength and durability.
