Frequently Asked Questions
Q1
What steel grade is used for the main frame, and why is hot-dip galvanizing important?
The main frame is constructed from high-strength Q235B Galvanized Steel treated with a hot-dip galvanizing process. This method applies a thick, uniform zinc coating that provides superior corrosion resistance compared to electro-galvanizing, significantly extending the structure's service life — especially in humid, coastal, or harsh outdoor environments.
Q2
What is the difference between the 75mm and 50mm sandwich panels used in the building?
The 75mm sandwich panels are used for exterior walls, providing greater thermal insulation and structural rigidity to protect against external temperature fluctuations. The 50mm sandwich panels are used for the roof and internal partitions where slightly less insulation thickness is sufficient. Both panels feature dual-sided 0.426mm color-coated steel and a 40kg/m³ core density for consistent high performance.
Q3
Can the electrical system be adapted for use in different countries or regions?
Yes. The electrical wiring, sockets, and components can be fully customized to comply with international standards including UL (North America), CE (Europe), and SAA (Australia). The system is pre-fitted with a 2P 63A Main Circuit Breaker and six Three-proof LED ceiling lights, and can be adapted before delivery to meet your local requirements.
Q4
Are custom sizes available beyond the standard 20ft and 40ft container models?
Absolutely. While standard 20ft and 40ft models are available as baseline options, our engineering team can produce units with fully custom lengths, widths, and heights to meet the specific requirements of your project. Simply provide your floor plans or dimensional drawings and we will engineer a solution accordingly.
Q5
What exterior finish and color options are available for the container building?
A wide range of exterior aesthetics can be specified using the RAL color system to achieve any solid color tone. In addition, textured finishes such as Wood Grain, Marble, and Industrial Metal are available to suit residential, commercial, or industrial project aesthetics. Custom branding colors can also be accommodated upon request.
Q6
How durable and fire-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 ideal for environments where safety and durability are priorities. The lateral floor uses 18mm Industrial Grade Construction Formwork, selected for its load-bearing strength and resistance to heavy daily use. Together, the flooring system meets commercial and industrial durability standards.
