💬 Frequently Asked Questions
Q
What type of steel is used in the main frame, and why is it galvanized?
The main frame uses high-strength Q235B Galvanized Steel with a hot-dip treatment process. Hot-dip galvanizing applies a thick zinc coating to the steel, providing superior resistance to rust, corrosion, and harsh outdoor environments — significantly extending the structure's lifespan compared to standard painted steel.
Q
What is the difference between the 75mm and 50mm sandwich panels?
The 75mm sandwich panels are used on exterior walls where greater thermal insulation and weather resistance are required. The 50mm panels are applied to the roof and internal partitions, balancing weight and insulation performance. Both use dual-sided 0.426mm color-coated steel and a core density of 40kg/m³ for consistent quality.
Q
Can the electrical system be customized to meet local safety standards?
Yes. All sockets and wiring configurations can be customized to comply with UL (United States), CE (Europe), or SAA (Australia) certification standards. Please specify your target market or applicable local regulations when placing your order so our engineering team can prepare the appropriate electrical layout.
Q
Are sizes limited to standard 20ft and 40ft container dimensions?
Not at all. While we offer standard 20ft and 40ft models as baseline configurations, our manufacturing process fully supports custom dimensions — including non-standard lengths, widths, and heights. Simply share your project specifications or architectural drawings, and our team will engineer a solution to match your exact requirements.
Q
What exterior finish and color options are available?
A wide range of exterior finishes is available under our bespoke customization program. You can select any color from the RAL Color System, and choose from surface textures including Wood Grain, Marble, and Industrial Metal. These options allow the unit to blend seamlessly with existing architecture or meet project branding requirements.
Q
Is it possible to modify the internal layout, door positions, and window placements?
Yes — we offer 100% flexible layout customization. Our engineering team can redesign internal partitions, relocate door openings, and adjust window positions based on your provided floor plans, drawings, or functional requirements. There is no fixed internal configuration, making these units highly adaptable for office, residential, retail, or site welfare applications.
