Frequently Asked Questions
Q
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 creates a robust zinc coating that protects the steel from rust, corrosion, and harsh weather conditions, significantly extending the structural lifespan of the building.
Q
What is the difference between the 75mm and 50mm sandwich panels?
The 75mm sandwich panels are used for exterior walls where greater thermal insulation and structural rigidity are required. The 50mm panels are applied to roofs and internal partitions, offering a lighter-weight solution while still maintaining excellent insulation performance with a core density of 40 kg/m³.
Q
Can the electrical system be adapted for different countries' standards?
Yes. All sockets and wiring configurations can be customized to comply with UL (North America), CE (Europe), or SAA (Australia) standards. The main circuit breaker is rated at 2P 63A to handle demanding electrical loads safely.
Q
Is it possible to order a unit with non-standard dimensions?
Absolutely. While standard 20ft and 40ft container office models are available, our engineering team supports fully custom dimensions — including modified lengths, widths, and heights — to meet the precise requirements of your construction site or project blueprint.
Q
What exterior finish and color options are available?
Exterior finishes can be selected from the full RAL color system, with texture options including Wood Grain, Marble, and Industrial Metal. This allows the modular building to blend seamlessly into various environments, from construction sites to commercial campuses.
Q
How fire-resistant and moisture-resistant is the flooring system?
The main floor uses 15mm Cement Fiber Board, which is engineered to be both fireproof and moisture-resistant — making it suitable for humid climates and environments with strict fire safety requirements. The lateral floor uses 18mm industrial-grade construction formwork for additional structural support and durability.
