container house installation

Importing container houses from China runs in seven steps: define the use case and unit type, confirm drawings and configuration, agree commercial terms, follow production and quality checks, approve the packing and container-loading plan, ship and clear customs, then install on site. Most delays and cost overruns happen at steps two and five — unclear specifications and an unplanned loading plan — not at sea. This guide covers the parts a manufacturer controls and can document. Customs classification, duty rates and local building approvals vary by destination and change frequently; for those, your freight forwarder and local certifier are the authority. Step 1: Define the Use Case and the Unit Type The phrase "container house" covers three different products with very different logistics. Choose before you ask for a quote, otherwise you will compare prices for different things. Type Best for Logistics character Quick-assembly flat-pack Camp offices, dormitories, welfare rooms, multi-unit blocks Ships as loose parts; highest loading density; assembled on site Folding container Projects that relocate often; rapid deployment Ships pre-assembled and folded; unfolds on site Double-wing expandable Fewer, larger self-contained living units Ships folded; unfolds to full width; lowest loading density Ask the factory for the dimension drawing of the exact model you are buying, in both transport and in-use states. Do not plan a site layout from a brochure size — confirm it against the drawing before production. Step 2: Confirm Drawings and Configuration A supplier can only quote accurately once the configuration is fixed. Confirm the items that change cost and compliance: Layout: number of rooms, bathroom, kitchen, and whether partitions are fixed Wall panel core and thickness, plus insulation requirements for your climate Door and window type, and the electrical standard of the destination country Floor finish, ceiling, and whether wiring is concealed Frame specification, including galvanizing and corrosion protection Wanbang's flat-pack line uses a high-strength galvanized steel frame with rock-wool sandwich panels that provide thermal insulation, fire resistance and moisture resistance — the specification to request in writing if your site is hot, humid, or remote. Step 3: Agree Commercial Terms Get every term in the contract, not in a chat message. The commercial fields published on Wanbang product pages are a useful reference for what to expect in writing: minimum order quantity of one unit, payment structured as 50% deposit and 50% before shipment, shipment from Nansha port (other Chinese ports available), and a published lead time of 10–15 days. Confirm the actual figures for your order and model in the contract — lead time depends on configuration and quantity. Step 4: Follow Production and Quality Checks Ask for evidence at three points: mid-production photos, pre-packing inspection, and container-loading photos. Wanbang documents inspection at each production stage and reports a 100% finished-product pass rate. If your project value or local compliance risk is significant, appoint an independent inspector before the balance payment. Step 5: Approve the Packing and Container-Loading Plan The loading plan decides your freight cost per unit. Ask how many units fit in a 40HQ, how much is pre-assembled in the factory versus assembled on site, and what goes into each container. Packing method Approx. units per 40HQ Trade-off Loose parts (knock-down) ≈ 14 sets Lowest freight per unit; more site assembly Pre-assembled packing ≈ 10 sets Less site work; higher freight per unit Pre-assembled, stacked ≈ 6 sets Least site work; highest freight per unit Figures above are Wanbang's published loading data for the flat-pack product line and vary by wall panel thickness and model — treat them as a planning baseline and confirm against your final specification. Step 6: Ship and Clear Customs Sea freight is standard for container houses; your forwarder selects between FCL and other options based on unit dimensions. Prepare the usual export set — commercial invoice, packing list, bill of lading and certificate of origin — and confirm document requirements with your forwarder. On customs, duties and local approvals: HS classification, duty rates, and building-approval or certification requirements differ by country and change often. Confirm them with your licensed customs broker, freight forwarder or local certifier before shipment. A manufacturer can supply product documentation and test data, but should not be your source for duty rates or local code compliance. Step 7: Install on Site Installation planning starts before the ship leaves: prepare the foundation, confirm crane access if required, and agree who provides the local crew. Support scope varies by product: Quick-assembly flat-pack: no welding and no crane needed — about 4 workers complete one unit in around 3 hours. Folding container: unfolds in 4 steps in roughly 15 minutes. Double-wing expandable: arrives folded and unfolds into the full-width layout on site. Ask the factory what comes in the box: drawings, installation manuals, instructional video, and remote guidance during your first units. FAQ How many container houses fit in a 40HQ container? For Wanbang's flat-pack line, published figures are about 14 sets per 40HQ shipped as loose parts, roughly 10 sets pre-assembled, and about 6 sets pre-assembled and stacked. Confirm against your model and wall panel thickness — the packing method is the variable that matters. How long does installation take? A quick-assembly flat-pack unit takes about 4 workers around 3 hours with no welding and no crane. A folding unit unfolds in 4 steps in roughly 15 minutes. Site preparation and foundation work are separate from these figures. Do I need a crane to install? Not for the quick-assembly flat-pack system, which is designed for bolted assembly without welding or crane lift. Folding and expandable units are lifted into position and then unfolded — confirm the requirement for your model before the container arrives. What payment terms are typical? The structure published on Wanbang product pages is 50% deposit with 50% balance before shipment. Always confirm the exact terms, currency and incoterms in the contract. Who handles customs clearance and import duties? Your freight forwarder or licensed customs broker. The factory provides commercial and technical documents; duty rates, HS classification and local approvals must be confirmed locally, as they vary by country and change over time. Planning an import?

Short answer: flat-pack container houses ship more units per container — 14 sets in one 40HQ — while folding container houses install far faster, at about 15 minutes per unit versus roughly 3 hours. If your cost driver is freight, flat-pack wins. If your constraint is site labour or speed, folding wins. Most projects choose based on which of those two pressures is heavier. Both types are factory-built steel-framed modular units shipped from China for workforce camps, site offices and remote accommodation. The difference is in how they travel. A flat-pack unit leaves the factory as loose components — panels, columns, beams and floor boards packed flat and stacked — and is assembled on site. A folding unit leaves the factory as a complete box that collapses to a fraction of its height and is unfolded on site. Side-by-side: the numbers that actually decide the order Item Quick-Assembly Flat-Pack Folding Container House Set-up dimensions 6055 × 2990 × 2896 mm 5900 × 2500 × 2470 mm Usable floor area per unit ≈ 18 m² ≈ 14.8 m² Shipping form Loose components, flat-packed Complete unit folded to 5900 × 2500 × 400 mm Volume when packed Flat stacked panels Compressed to about 1/6 of set-up volume Loading per 40HQ 14 sets 10 sets (50 mm wall panel) / 8 sets (75 mm wall panel) Installation About 4 workers, ~3 hours per unit About 4 steps, ~15 minutes per unit Site equipment No welding, no crane required Unfolding sequence, no welding Why the "folding" one ships fewer units This is the part buyers find counter-intuitive. A folding unit compresses to roughly one sixth of its volume — so it should ship better, right? In practice, what you are shipping is still a whole box: floor, roof, wall panels and frame folded together, 400 mm thick once collapsed. A flat-pack unit, by contrast, is broken down into its individual parts, which stack with almost no wasted air between them. The result: 14 flat-pack sets per 40HQ against 10 folding sets (8 sets if you specify the thicker 75 mm wall panels). On a project that needs 40 or 100 units, that difference is several containers of freight, and freight is often the single largest variable cost in a container house order. Where the folding unit wins: time on site Flat-pack assembly is straightforward — bolted connections between columns and top/bottom beams, with wall and floor panels fixed in sequence — but it is still an assembly job: about four workers and three hours per unit. Folding units reverse that. The unit arrives as a finished box, and the site work is a short unfolding sequence measured in minutes. That matters in three situations: Tight mobilisation windows — a camp that must be habitable this week rather than next month. Expensive or scarce site labour — remote mining and power projects where a skilled crew costs far more than a container slot. Repeat relocation — camps that move as the work front moves along a transmission line or haul road. Usable space: flat-pack gives you more per unit Per unit, the flat-pack footprint is larger: roughly 18 m² against roughly 14.8 m² for the folding unit. If you are fitting dorms, a kitchen block or a site office into a fixed number of units, that difference changes how many units you have to buy in the first place — which partly offsets the freight advantage, and is worth doing the arithmetic on before you commit. How to choose in practice Choose flat-pack when Freight cost per unit is your main lever — 14 sets per 40HQ is the best loading figure we can offer. The camp is a fixed, long-term installation. You need the larger per-unit floor area for dorms, offices or kitchen blocks. You want individual components replaceable without scrapping a whole unit. Choose folding when Speed of deployment is the binding constraint. Site labour is expensive, limited, or short-windowed. The camp is expected to be relocated during the project. You prefer a unit that arrives finished and simply opens. Practical tip: send us your headcount, site location and project duration, and we will run both options through the same container-loading calculation. The answer usually becomes obvious once freight and site labour are priced against each other for your specific country. Frequently asked questions Which type is cheaper to ship? Flat-pack, in units per container: 14 sets per 40HQ versus 10 sets (50 mm panels) or 8 sets (75 mm panels) for folding units. On large orders that typically means fewer containers. Which type installs faster? Folding units — roughly 15 minutes per unit through a four-step sequence, compared with about three hours for a four-worker crew assembling a flat-pack unit. Can both types go in the same shipment? Yes. Mixed shipments are common when a project needs fast-deployment units for the first phase and flat-pack units for the permanent camp. Loading plans are calculated per order, because the two types do not stack the same way. Which is better for a long-term fixed camp? Usually flat-pack. It gives more usable area per unit, assembles into a rigid bolted structure, and is designed for a service life measured in years rather than a temporary stopover. Folding units suit shorter or mobile deployments better. Do both types need a crane or welding on site? Flat-pack assembly needs no welding and no crane. Folding units are set down and unfolded. Site requirements still depend on ground conditions and your foundation design, which we confirm per project.
