Container Houses

Mainstream Types

Based on structure and purpose, container houses are mainly divided into the following categories:

· Standard Site Accommodation Container: The most basic residential container unit, approximately 6 m × 3 m × 2.8 m, mainly used for worker dormitories and temporary offices.

· Combined Office Container: Multiple standard containers are connected horizontally and/or vertically to create a large office space, with the option to stack 2 to 3 floors.

· Flat-Pack Container House: Composed of a top frame, bottom frame, corner posts, and 14 interchangeable wall panels; it can be flat-packed for transportation.

· Premium Homestay Container: Focuses on exterior design and living comfort, often using light steel keel structures with wood veneer finishes, and equipped with private bathrooms and smart home systems.

· Corrugated Container: Uses wave-shaped or corrugated steel panels, offering high strength, excellent drainage performance, and a distinctive industrial appearance.

Specifications

Structure and Materials

· Frame System: Q235B hot-dip galvanized square steel with full welding; the main frame steel thickness is typically 2.0–3.0 mm, providing excellent corrosion and rust resistance.

· Wall Panel System: 75 mm thick rock wool sandwich panels (Class A fire-resistant), with a density of no less than 80 kg/m³; EPS, polyurethane, and other core materials are also available.

· Roof System: 0.4 mm color steel single tile + 75 mm glass wool insulation layer + aluminum foil paper, with a 360-degree fully sealed interlocking waterproof design.

· Floor System: Cement fiber board + insulation layer + magnesium oxide board/multilayer plywood + PVC flooring.

· Doors and Windows: Steel door sets, PVC sliding windows, or thermal-break aluminum doors and windows, with double-layer hollow tempered glass.

· Surface Treatment: Electrostatic spraying (white); colors can be customized.

· Electrical System: Concealed installation of PVC flame-retardant conduits, sufficient reserved sockets, and 220 V standard voltage.

Installation and Transportation

· Production Method: Factory-based modular prefabrication and standardized mass production.

· Transportation Method: Standard containers can be transported as complete units, while flat-pack containers can be shipped in flat packages, greatly saving logistics space.

· Installation Speed: Two people can complete the assembly of a 20㎡ unit in about 4 hours; for standard containers, it usually takes only 3–5 days on average from dispatch to completion of on-site assembly.

· Connection Method: Supports vertical stacking and side-by-side connection, allowing combination into large spaces such as 40-foot, 60-foot, and 80-foot units.

· Foundation Requirements: No complex foundation is required; it can be placed on a flat and hardened ground surface.

Core Advantages

· Rapid Deployment: More than 90% factory prefabrication, extremely fast on-site installation, and ready for use once connected to power.

· Reusable and Relocatable: Can be relocated and reused multiple times, with a high reuse rate and low lifecycle cost.

· Safe and Robust: Designed for seismic intensity 8 and wind resistance grade 10–12, with strong load-bearing capacity from the steel structure.

· Fireproof and Waterproof: Rock wool panels provide Class A fire resistance, and the roof adopts a 360-degree fully sealed interlocking waterproof design.

· Flexible Combination: Supports horizontal connection and vertical stacking, offering high flexibility for space expansion.

· Green and Eco-Friendly: Produces no construction waste on site, uses recyclable materials, and meets green building standards.

· Thermal Insulation: High-quality products can achieve an indoor-outdoor temperature difference of 8–10℃ in summer.

Interior Configuration

Container houses can be fully finished in the factory. Common configurations include:

· Functional Layout: Can be customized as a single room, double room, one-bedroom living unit, and more.

· Bathroom: Private bathroom equipped with a washbasin, toilet, and shower.

· Kitchen: Simple cabinets + countertop, with reserved water and electrical interfaces.

· Air Conditioning: Reserved position for an external wall-mounted air conditioner unit.

· Water and Electrical Systems: PPR water pipes + PVC flame-retardant electrical conduits, prefabricated as an integrated system in the factory.

· Optional Configurations: Smart home system, electric curtains, water heater, furniture, and more.

Application Scenarios

· Construction Camps: Worker dormitories, project department offices, meeting rooms, and canteens.

· Cultural Tourism and Homestays: Scenic area accommodation, supporting facilities for campsites, and rural homestay clusters.

· Commercial Buildings: Container commercial blocks, coffee shops, pop-up stores, and exhibition centers.

· Emergency Relief: Post-disaster resettlement sites, temporary medical points, and emergency command centers.

· Municipal Facilities: Public toilets, guard booths, police service rooms, and waste sorting stations.

· Overseas Projects: Exported to Southeast Asia, the Middle East, Africa, and other regions to meet the needs of international construction camps.

Purchasing Considerations

· Verify Steel Thickness: A main frame thickness of 2.0–3.0 mm is recommended to avoid low-cost thin-walled products with insufficient load-bearing capacity.

· Confirm Fire Rating: Give priority to Class A fire-resistant rock wool panels and request third-party fire test reports.

· Inspect Welding Quality: Full welding is superior to spot welding and provides a stronger structure.

· Pay Attention to Waterproof Details: Roof interlocking technology and the quality of sealing strips directly affect waterproof performance.

· Verify Insulation Materials: Rock wool density should be no less than 80 kg/m³ for more reliable thermal insulation.

· Confirm After-Sales Terms: Warranty period, response time, spare parts supply, and other terms should be clearly specified in the contract.

Comparison with Other Modular Houses

Container houses are the most mature and largest-market-share category among modular integrated houses. In 2025, the domestic integrated housing market exceeded RMB 30 billion, with container mobile houses accounting for more than 40%.
