Frequently Asked Questions
Q
What type of steel is used for the main frame, and why is galvanization important?
A
The main frame is constructed from high-strength Q235B Galvanized Steel using a hot-dip galvanizing process. This treatment provides exceptional corrosion resistance, extending the structural lifespan significantly — especially in humid, coastal, or high-rainfall environments.
Q
What is the difference between the 75mm and 50mm sandwich panels used in this building?
A
The 75mm sandwich panel is applied to exterior walls for superior thermal insulation and weather resistance, while the 50mm panel is used for the roof and internal partitions where a balance of insulation and weight is required. Both use dual-sided 0.426mm color-coated steel facing.
Q
Can the electrical system be configured to meet different international standards?
A
Yes. All sockets and internal wiring can be fully customized to comply with UL (North America), CE (Europe), or SAA (Australia) standards, making this building suitable for deployment across multiple countries and regions.
Q
Are sizes limited to standard 20ft and 40ft container dimensions?
A
Not at all. While standard 20ft and 40ft models are available, our engineering team offers fully adjustable dimensions — custom lengths, widths, and heights — to match your specific project site requirements and architectural plans.
Q
What exterior finish and color options are available for the building?
A
A wide range of exterior aesthetics are available. You can choose from any RAL color system palette as well as specialty textures including Wood Grain, Marble, and Industrial Metal finishes, allowing the structure to blend seamlessly with its surrounding environment.
Q
Is the flooring suitable for heavy industrial use, and is it resistant to moisture and fire?
A
The main floor uses a 15mm Cement Fiber Board that is both fireproof and moisture-resistant, making it ideal for demanding environments. The lateral floor is reinforced with 18mm Industrial Grade Construction Formwork, providing additional load-bearing capacity for heavy-duty applications.
