Frequently Asked Questions
What type of steel is used in the main frame, and why is it important?
The main frame is constructed from high-strength Q235B Galvanized Steel with hot-dip treatment. This ensures excellent corrosion resistance, structural rigidity, and long-term durability — making it suitable for demanding outdoor environments and extended service life.
What is the difference between the 75mm and 50mm sandwich panels?
The 75mm sandwich panels are used for exterior walls to provide superior thermal insulation and weather resistance. The 50mm panels are applied on the roof and internal partitions where slightly less insulation thickness is required. Both use dual-sided 0.426mm color-coated steel sheets and a 40kg/m³ high-density core for optimal performance.
Is the flooring fireproof and moisture-resistant?
Yes. The main floor uses a 15mm Cement Fiber Board that is specifically engineered to be both fireproof and moisture-resistant — ideal for use in humid climates, construction sites, or locations with high foot traffic. The lateral floor uses 18mm industrial-grade construction formwork for added load-bearing strength.
What electrical compliance standards are supported?
The electrical system can be customized to meet UL (United States), CE (Europe), and SAA (Australia) standards. The system includes a 2P 63A main circuit breaker and six high-efficiency Three-proof LED ceiling lights, with socket configurations adaptable to local requirements.
Can the container office dimensions be customized beyond standard 20ft and 40ft sizes?
Absolutely. In addition to standard 20ft and 40ft models, our engineering team offers fully custom sizing — including adjustable lengths, widths, and heights — to meet your specific project or site requirements. Simply provide your floor plan or drawings and we will tailor the design accordingly.
What exterior finish and color options are available?
A wide range of exterior aesthetics is available, including multiple colors based on the RAL color system, as well as textured finishes such as Wood Grain, Marble, and Industrial Metal. This allows the container office to blend seamlessly with different architectural environments or brand identities.
