Frequently Asked Questions
What type of steel is used in the main frame, and why is it hot-dip galvanized?
The main frame is constructed from high-strength Q235B steel, which offers excellent structural integrity and weldability. Hot-dip galvanizing applies a thick, metallurgically bonded zinc coating that provides superior long-term corrosion resistance compared to standard paint or spray coatings — ideal for outdoor and harsh-environment deployments.
What is the difference between the 75mm and 50mm sandwich panels used in this structure?
The 75mm sandwich panels are used on exterior walls where greater thermal insulation and weather resistance are required, while the 50mm panels are applied to the roof and internal partitions. Both feature dual-sided 0.426mm color-coated steel skins and a high-density 40kg/m³ insulation core for consistent performance throughout the structure.
Can the electrical system be adapted for use in different countries with different standards?
Yes. The wiring, sockets, and electrical components can be customized to comply with UL (North America), CE (Europe), or SAA (Australia) standards. Simply specify your target market during the ordering process, and our engineering team will configure the system accordingly.
Are sizes limited to standard 20ft and 40ft container dimensions?
Not at all. While standard 20ft and 40ft models are available as ready configurations, we offer fully adjustable dimensions in length, width, and height. Custom sizes are engineered to match your specific project drawings and site constraints, making these units suitable for a wide variety of applications.
What exterior finish and color options are available for the modular units?
Exterior finishes can be selected from the full RAL color system, ensuring precise color matching for branding or site requirements. Texture options include Wood Grain, Marble, and Industrial Metal, allowing the units to blend with architectural surroundings or meet specific aesthetic standards.
Is the flooring suitable for heavy industrial use or high foot-traffic environments?
Yes. The main floor uses a 15mm Cement Fiber Board that is both fireproof and moisture-resistant, making it durable under demanding conditions. The lateral floor incorporates 18mm industrial-grade construction form-work for added load-bearing capacity, ensuring reliable performance in workshops, site offices, and other high-use applications.
