Frequently Asked Questions
Q
What type of steel is used in the main frame, and why is hot-dip galvanizing important?
A
The main frame is built from Q235B Galvanized Steel treated through a hot-dip galvanizing process. This coating method bonds a protective zinc layer deeply into the steel surface, providing superior corrosion resistance compared to standard paint or electroplating — making it ideal for long-term outdoor and harsh-environment deployments.
Q
What is the difference between the 75mm and 50mm sandwich panels used in this unit?
A
The 75mm sandwich panel is used for exterior walls where greater thermal insulation and structural rigidity are required. The 50mm sandwich panel is applied to the roof and internal partitions, offering a lighter-weight solution while still meeting insulation and fire resistance standards. Both use dual-sided 0.426mm color-coated steel facings.
Q
Can the electrical system be customized to meet local safety standards in my country?
A
Yes. The electrical configuration — including sockets, outlet types, and wiring specifications — can be tailored to comply with UL (North America), CE (Europe), SAA (Australia), or other regional standards. Please confirm your target market requirements before placing your order so our engineering team can configure accordingly.
Q
Is it possible to order a unit with dimensions other than the standard 20ft or 40ft?
A
Absolutely. While 20ft and 40ft are our standard container office sizes, we offer fully customizable dimensions — including custom lengths, widths, and heights — to suit unique site requirements or architectural plans. Our engineering team will work from your drawings to ensure a perfect fit for your project.
Q
What exterior finish and color options are available for the outer panels?
A
Exterior finishes are available in a wide selection of colors using the RAL color system for precise matching. Surface textures include Wood Grain, Marble, and Industrial Metal patterns, allowing the unit to be adapted for office, commercial, residential, or site-specific aesthetic requirements.
Q
Why is cement fiber board used for the main floor instead of standard wood or tile?
A
The 15mm Cement Fiber Board selected for the main floor provides excellent fireproof and moisture-resistant properties, making it far more durable in demanding environments compared to conventional timber or tile options. It resists warping, water damage, and is compliant with fire safety regulations — critical for modular building applications.
