Frequently Asked Questions
Q
What type of steel is used for the main frame, and why is hot-dip galvanization important?
The main frame is constructed from high-strength Q235B Galvanized Steel treated with a hot-dip galvanization process. This treatment forms a thick, metallurgically bonded zinc coating that provides superior corrosion resistance compared to electro-galvanizing, making it ideal for long-term outdoor use and harsh environments.
Q
What is the difference between the 75mm and 50mm sandwich panels used in this building?
The 75mm sandwich panels are used for exterior walls, providing enhanced thermal insulation and structural rigidity against outdoor temperatures. The 50mm sandwich panels are applied to the roof and internal partitions, balancing weight reduction with sufficient insulation performance. Both panels feature dual-sided 0.426mm color-coated steel skins with a 40kg/m³ core density.
Q
Can the electrical system be customized to comply with different international standards?
Yes. All sockets and internal wiring can be configured to meet UL (North America), CE (Europe), or SAA (Australia) compliance standards upon request. The main circuit breaker is a high-standard 2P 63A unit, and the lighting system features six three-proof LED ceiling lights suitable for demanding environments.
Q
Is it possible to order a custom size beyond the standard 20ft and 40ft models?
Absolutely. Our engineering team offers fully adjustable dimensions including custom lengths, widths, and heights. Whether your project requires a compact unit or an oversized modular building, we can tailor the specifications to meet your exact requirements based on submitted drawings or floor plans.
Q
What exterior finish and color options are available for the container building?
We offer a wide range of surface finish options through the RAL color system, allowing precise color matching for any project. In addition to standard painted finishes, decorative textures such as Wood Grain, Marble, and Industrial Metal are available to suit various architectural aesthetics and branding requirements.
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 demanding climates and safety-regulated environments. The lateral floor is reinforced with 18mm Industrial Grade Construction Formwork to provide additional load-bearing strength and dimensional stability across the entire floor structure.
