Prefab Container House FAQs

A prefab container house is a factory-engineered modular building system constructed from cold-formed hot-dip galvanized steel frames integrated with insulated structural sandwich panels. Unlike discarded shipping containers, purpose-built prefab modules feature optimized room dimensions, engineered ceiling-to-floor load transfer pathways, and pre-fitted wall openings for immediate structural assembly.

Our Gen-2 detachable and flat-pack modules are built specifically for coastal and severe weather zones. Key structural protections include:

• Heavy-Duty Corner Posts: 2.5mm to 3.0mm thick galvanized steel columns bolted directly into corner castings.
• Concealed Drainage System: Sloped roof frames with 4 internal corner downpipes capable of discharging over 150mm/hr of rainfall without overflow.
• Double-Sealed Panel Joints: EPDM weather-stripping gaskets and structural silicone sealants eliminate rainwater penetration completely.

We supply three main core insulation materials for wall and roof sandwich panels, selectable according to project thermal and fire code standards:

• EPS (Expanded Polystyrene): Cost-effective thermal barrier suitable for general site offices and temporary dormitories.
• Rockwool (Mineral Wool): Class-A non-combustible material offering superior acoustic damping and high fire endurance (up to 2 hours).
• PU / PIR (Polyurethane): Highest R-value thermal performance, ideal for cold-chain facilities, luxury residential cabins, and high-heat tropical regions.

Freight loading efficiency is a primary driver of landed project costs. Our standardized packing configurations include:

• Flat Pack Container House: 4 standard 20ft sets bundled together as ISO-dimensioned packages per 40HQ container.
• Z-Type Foldable Container House: Up to 10 to 14 folded modules per 40HQ or flatbed truck load.
• X-Type Foldable Container House: Folds down to just ~42cm in height, fitting up to 16 units per truck load for emergency mobilization.
• Detachable Container House: Knock-down components packed in bulk allow up to 15 to 18 sets per 40HQ container.

All steel elements receive a hot-dip galvanizing treatment followed by electrostatic powder coating. During packing, steel surfaces are wrapped with anti-abrasion protective film, corners are fitted with reinforced edge protectors, and hardware accessories are sealed in moisture-proof wooden crates with desiccant packs.

Prefab container houses require simple, economical ground preparation compared to conventional masonry buildings. Recommended foundations include:

• Concrete Point Blocks: Concrete piers set at module corner post positions (ideal for quick, low-cost setup).
• Concrete Strip Footings: Perimeter concrete beams supporting edge frames on soft or uneven ground.
• Flat Concrete Slab: A standard 100mm-150mm thick slab for long-term multi-story camp installations.
• Ground Screws / Steel Pilings: Environmentally friendly option for sloped landscapes, eco-resorts, and sensitive soils.

For standard 20ft Flat Pack or Detachable modules, a trained crew of 3 to 4 installers with basic equipment (electric hand drills, wrenches, crane or forklift hoist, leveling tools, and weather sealant guns) can complete 1 unit in 2 to 3 hours. Foldable models require no heavy cranes and can be expanded manually or with a simple pulley system in under 15 minutes.

Yes. Flat Pack and Detachable container modules can be stacked up to 3 stories high without additional external structural steelwork. Modules can also be combined horizontally by omitting interior wall panels to create wide open-plan spaces such as open office layouts, large dining halls, field hospitals, or dormitory complexes.

Every series features factory pre-integrated MEP conduits. Electrical boxes, distribution breakers, LED lighting, and power outlets are pre-wired to meet national standards (220V/110V, BS/EU/US/AU socket standards). Plumbing modules feature pre-fitted PEX water supply lines, PVC drain pipes, and leak-tested integrated floor drain pans.

Yes. Our reinforced roof frames are engineered to support rooftop solar panel mounting brackets, inverters, and battery storage units. Solar-ready DC conduit pathways can be factory pre-routed to facilitate fast off-grid installation for remote mining camps, island sites, and eco-resorts.
