What is a flat pack container house?
A flat pack container house is a modular prefabricated building that is manufactured in the factory and transported in a compact form. It can be quickly assembled at the project site.
Can the size and design be customized?
Yes. The size, layout, materials, colors, doors, windows, and overall design can be customized according to customer requirements.
How long does installation take?
Installation time depends on the project size and quantity. Standard modular units can usually be assembled much faster than traditional buildings.
What projects are suitable for this container house?
It is widely used for construction sites, accommodation camps, offices, storage buildings, industrial projects, schools, and emergency facilities.
Can multiple units be connected together?
Yes. Multiple container units can be combined horizontally or vertically to create larger modular buildings.
How long do Qinglin House container houses last, and how are they protected against rust and corrosion?
- Hot-dip galvanized steel frame: our main frames use galvanized (zinc-coated) steel, forming a metallurgical bond that resists rust far better than spray-painted frames. This is especially important for coastal sites or humid climates.
- Expected lifespan: with proper installation and routine maintenance, a well-built container house can last 30–50 years or more, comparable to conventional construction.
- Rust-first engineering: we protect both the frame and connections, so doors and windows keep sealing properly and the structure stays rigid over time.
What sizes and models are available, and can modules be combined into larger spaces?
We offer a full range of standardized and customizable units to match different projects:
- Standard models: 20ft / 40ft expandable container houses, foldable (collapsible) containers, double-wing expandable units, and mobile space capsules.
- Application-specific units: site offices, dormitories, container toilets, medical/health cabins, coffee kiosks, canteens (e.g. 6m × 8m), and double-story homestay units (e.g. 3m × 6m).
- Modular combination: multiple modules can be spliced side-by-side or stacked to create larger layouts — from single studios to multi-bedroom homes, two-story villas and whole worker camps.
Do you offer customization?
Yes — full customization is available to match your site, style and budget:
- Layout & interior: door/window placement, room division, interior design style, bathroom fixtures.
- Exterior: wall color, cladding materials, logo branding, RAL custom colors, and features like glass curtain walls, terraces and wooden decks.
- Materials & insulation: choose EPS or rock-wool sandwich panels, insulation thickness, and flooring — suited to hot, cold or humid climates.
- Technical: electrical circuits, power systems and certifications can be tailored to your country's requirements. Send us your drawings or requirements and we'll advise the best configuration.
What are your MOQ, production lead time and shipping arrangements?
We support both trial orders and large-scale projects, with flexible options:
- MOQ & packing: as a guide — approx. 2 units per 40HQ for 20ft expandable houses, 1 unit per 40HQ for 40ft expandable houses, and about 10 units per 40HQ for foldable (Z-type) units. Exact MOQ varies by model and customization.
- Production lead time: roughly 7–15 working days for standard models and 15–30 working days for customized products, confirmed upon order.
- Logistics: foldable and modular designs are packed to minimize shipping volume and reduce your freight cost. We've exported to 35+ countries across Australia/NZ, Europe, the Middle East and Africa.
How is installation carried out, and what site preparation do we need?
Our units are designed for fast, low-skill on-site assembly:
- Foundation: do not place a container house directly on bare ground or grass — soil moisture corrodes steel and uneven settling distorts doors/windows. Prepare a level foundation: compacted gravel with level concrete blocks/pillars at all load points, or ideally a concrete slab / screw piles for permanent use.
- No on-site welding: panels and frames are factory pre-drilled and bolt together, like building blocks — no skilled welders required.
- Time & crane: most expandable/foldable units can be set up in a matter of hours with one crane for lifting and expanding; specific requirements are provided in the installation manual.
It integrates prefabricated housing, packing boxes, quick-assembly boxes, metal products,
prefabricated houses and other temporary construction facilities.
