Frequently Asked Questions
Q
What steel grade is used for the main frame, and why is hot-dip galvanizing important?
The main frame is constructed from Q235B Galvanized Steel treated with a hot-dip galvanizing process. This method provides a thick, uniform zinc coating that bonds metallurgically to the steel, offering superior corrosion resistance compared to electroplating. It significantly extends the structural lifespan, making it ideal for outdoor and harsh-environment deployments.
Q
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 weather resistance due to the thicker core. The 50mm sandwich panels are applied to the roof and internal partitions, balancing weight efficiency with adequate insulation. Both panels feature dual-sided 0.426mm color-coated steel for durability and aesthetics.
Q
Can the electrical system be adapted for use in different countries with varying standards?
Yes. All sockets, wiring, and components can be customized to comply with international standards including UL (North America), CE (Europe), and SAA (Australia). This ensures the unit is project-ready upon delivery without requiring costly on-site electrical modifications.
Q
Are custom dimensions available beyond the standard 20ft and 40ft container sizes?
Absolutely. While standard 20ft and 40ft models are available for most applications, our engineering team offers fully adjustable dimensions — including custom lengths, widths, and heights — to accommodate unique project requirements such as irregular site layouts, multi-level configurations, or special-purpose facilities.
Q
What exterior finish and color options are available for the container building?
A wide range of surface finish options are available through the RAL Color System, allowing precise color matching. Texture choices include Wood Grain, Marble, and Industrial Metal finishes, enabling the structure to blend into residential, commercial, or industrial environments as required.
Q
How fire-resistant and moisture-resistant is the flooring system?
The main flooring utilizes a 15mm Cement Fiber Board, which is engineered specifically for both fireproof and moisture-resistant performance — critical for modular buildings exposed to variable climates or high-humidity environments. The lateral floor is reinforced with 18mm industrial-grade construction formwork to provide additional structural load support.
