Flat-base expandable container houses prioritize stability, adaptability, and scalability, offering a cost-effective and sustainable solution for modern modular living and commercial needs.
  • Structural Stability & Adaptability: Even Load Distribution: The flat base offers a larger contact area, dispersing pressure effectively. It adapts to diverse terrains (sand, grass, mud) without complex foundations. Wind & Earthquake Resistance: Low center of gravity and steel structure enhance safety, ideal for disaster-prone areas.
  • Flexible Modular Expansion: Horizontal/Vertical Connection: Standardized flat-base interfaces enable rapid assembly with other containers, creating multi-story or large-scale spaces (e.g., residences, offices, warehouses). Multi-Scenario Use: Operate as standalone units or combined communities for temporary housing, commercial projects, or emergencies.
  • Cost & Efficiency Advantages: Easy Transportation: Flat-base structure fits standard container transport (trucks, ships), reducing logistics costs. Rapid Deployment: Factory prefabrication cuts on-site construction time by over 50% and minimizes labor costs.
  • Space Optimization: Smooth Layout: Flat interior surfaces support customized furniture and equipment placement, maximizing space utility. Vertical Potential: Stacking or adding stairs enables multi-level designs (e.g., LOFT layouts).
  • Durability & Low Maintenance: Corrosion Resistance: Galvanized/coated steel withstands humidity, heat, and harsh environments, with a lifespan exceeding 50 years. Easy Maintenance: Flat surfaces simplify cleaning and repairs, ensuring long-term cost control.

Products Description
Detailed specifications sketch
The quality of our factory and other factories is completely different. Taking the framework as an example, we use the latest design and the best materials, and the main frame of the craft house is the most important component. The materials and craftsmanship quality determine the service life and stability of the house. During the sales process, our customers reported that the repeatedly used cranes to transport the house, which may damage the frame, so we upgraded all 8 hanging heads of the house to cast iron, so that the frame will not be damaged even if it is moved multiple times.
The bottom frame of the house determines whether the house is stable, and we upgraded the density of the bottom of the frame. Our frame spacing is 32 cm. Compared with other factories, they are 45 cm. Our frame is more stable and will not shake when walking around the house. We have upgraded the design of the bottom frame flush, with the height of the frame on both sides and the middle, but the sides of other factories need to be padded with brick or wood to be level with the middle. But this will have several great impacts:
1. There is no contact with the ground on both sides of the house, causing the house to shake very seriously.
2. Due to the use of mats, it is impossible to make the side and middle part of the house completely horizontal, which affects the drainage of the bathroom. We have encountered situations where the drainage cannot be discharged by purchasing other factory houses.
Our folding part connectors have a hidden design, which has many benefits: The gaps on the floor are very small, which is not only more beautiful, but also improves thermal insulation. Hidden hinges are less likely to be damaged and will not wear. The frames are all galvanized and then sprayed with plastic treatment, including the link part of the wall panel. Doing so will give the frame a good anti-rust effect and a longer service life. The thickness of the main frame is 2.5-3mm, making it more durable.

  • 1. The internal flooring of our houses features a 20mm calcium silicate board and anti-corrosive multi-layer bamboo-wood composite board. Our composite board undergoes special treatment, with a coated surface using a process that is waterproof, moisture-resistant, and anti-corrosive.
  • 2. The house walls are constructed with fire-resistant and flame-retardant 75mm EPS sandwich panel, coupled with a lightweight steel frame design. This ensures strong structural waterproofing, seismic resistance, excellent thermal insulation, and robust resistance to moisture and termite damage.
  • 3. We use polyurethane adhesive sealant instead of traditional oil-based sealants. The polyurethane sealant provides superior sealing, meeting your requirements without causing any issues such as leakage.
  • 4. All doors and windows are crafted using aluminum alloy materials and double-layer insulated glass, offering effective thermal and sound insulation with heightened security.
  • 5. We take care of the installation of plumbing and electrical systems, ensuring compliance with your country's electrical safety standards.
The visible parts of the house can be customized, including doors, windows, interior and exterior walls, roof, etc. Color, material, version, thickness, etc. can be customized according to customer needs.

Frequently Asked Questions
What sizes do these expandable container houses come in?
We offer two standard configurations: The 20FT container house has an open size of 5900*6540*2530mm with a total area of 39 m², and the 40FT container house has an open size of 11800*6540*2530mm with a total area of 77 m².
Can the layout and design of the prefab house be customized?
Yes. All visible parts of the house, including the doors, windows, interior/exterior walls, ceiling, roof structure, colors, material versions, and thicknesses can be customized to suit your requirements.
Are the container houses durable and resistant to weather hazards?
Absolutely. The structures use fully welded galvanized frames (2.5-3mm thickness) and 75mm fireproof, flame-retardant EPS sandwich insulation panels, providing excellent resistance to fire, moisture, earthquakes, termites, and extreme weather.
What improvements have been made to ensure the stability of the bottom frame?
We have upgraded our frame structure density with a spacing of just 32cm compared to the standard 45cm of other suppliers. This ensures that the floor is extremely stable and does not shake. In addition, the design is flush-bottomed, eliminating the need to pad the sides with brick or wood.
Do the electrical and plumbing systems match local standards?
Yes, all internal wiring and plumbing systems are pre-installed in the factory and configured to comply with the destination country's electrical safety certifications (such as SAA or CE).
How are the components sealed to prevent water leakage?
We use high-quality polyurethane adhesive sealants rather than standard oil-based sealants. This ensures excellent durability, weather resistance, and completely eliminates water leakage problems.
