💬 Frequently Asked Questions
Q
What type of steel is used in the main frame, and why is hot-dip galvanizing important?
The main frame is constructed from high-strength Q235B Galvanized Steel processed through hot-dip galvanizing. This treatment provides a thick, bonded zinc coating that protects the steel from rust and corrosion — significantly extending the structural lifespan, especially in humid or coastal environments.
Q
What is the difference between the 75mm and 50mm sandwich panels used in this building?
The 75mm sandwich panel is used for exterior walls, providing greater thermal insulation and structural rigidity against external conditions. The 50mm sandwich panel is applied to roofs and internal partitions, offering a balanced weight-to-insulation ratio suitable for those applications. Both panels feature dual-sided 0.426mm color-coated steel facing.
Q
Can the electrical system be customized to meet local safety standards?
Yes. All sockets and wiring can be configured to comply with UL (United States), CE (Europe), or SAA (Australia) standards, depending on your destination country and project requirements. The system also includes a high-standard 2P 63A main circuit breaker for reliable overload protection.
Q
Is it possible to get a custom size beyond the standard 20ft or 40ft container dimensions?
Absolutely. In addition to standard 20ft and 40ft configurations, our engineering team offers fully custom dimensions — including non-standard lengths, widths, and heights — to precisely fit your site layout and operational requirements.
Q
What flooring options are available, and are they suitable for heavy-duty use?
The primary flooring 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 excellent load-bearing capacity and durability for heavy-duty applications.
Q
What exterior finish and color options are available for the building?
A wide range of exterior aesthetics are available through the RAL color system, allowing you to specify virtually any standard color. In addition, decorative surface textures including Wood Grain, Marble, and Industrial Metal finishes can be applied to suit your architectural vision or branding requirements.
