Detachable vs. Flat Pack Container Houses

Detachable vs. Flat Pack Container Houses

February 12, 2026

When exploring prefabricated container housing solutions, you'll have two popular options: Detachable Container Houses and Flat-pack Container Houses. While both types of prefabricated housing offer distinct advantages, they differ significantly in structural design, transportation methods, installation, and applications.

 

DXH House is a professional Chinese container housing supplier with over 10 years of experience manufacturing both types. We have delivered thousands of units to construction sites, commercial developments, and residential projects worldwide. This guide provides a comprehensive overview of everything you need to know, comparing them across multiple dimensions—including materials, construction processes, and cost-effectiveness—to help you quickly identify the prefabricated container building solution best suited to your needs.

 

What Are Detachable Container Houses?

 

Detachable container houses, also known as "quick assembly containers," are modular steel-frame structures designed for maximum flexibility and reusability. These units ship completely disassembled, with every component—columns, beams, wall panels, roof sections, and floor frames—packed separately and connected on-site using bolts and fastening screws.

 

Key Features of Detachable Container Houses:

 

  • Bolt-together Construction: No welding required during assembly or disassembly
  • Loading Capacity: 17-18 units per 40HQ
  • Reuse Capability: Can be disassembled and reassembled numerous times
  • Flexible Assembly: Columns connect to beams with visible carriage bolts
  • External Drainage: Rainwater drains through holes around the top perimeter

 

Installation Steps for Detachable Container Houses:

 

  • 1. Prepare the foundation (concrete slab or pile foundation)
  • 2. Sort components by type
  • 3. Bolt together the base frame
  • 4. Install corner posts and connect to the foundation
  • 5. Secure wall panels to the frame
  • 6. Install the roof frame and roof panels
  • 7. Secure all joints and apply sealant
  • 8. Install doors, windows, and interior finishes
  • 9. Connect utilities (electricity, plumbing)

What Are Flat Pack Container Homes?

 

Flat-pack container homes enable rapid assembly of complete homes, offering easy relocation, convenient storage, and the ability to be reused multiple times as temporary housing. These units feature factory-welded top and bottom frames, with wall panels and other components shipped separately for on-site assembly.

 

Key Features of Flat Pack Container Houses:

 

  • Welded Frame Construction: Top and bottom beams are pre-welded to columns at the factory
  • Internal Drainage System: Built-in gutters and four drainage pipes route water through columns
  • Rigid Structure: Frame and beam combination provides superior stability
  • Flush Alignment: Internal hex bolts create seamless connections when stacking units
  • Weather-tight Design: Factory-welded components enhance waterproofing
  • Loading Capacity: 6 units per 40HQ

 

Installation Steps for Flat-Pack Container Houses:

 

  • 1. Prepare the foundation and unpack the containers
  • 2. Position the pre-welded base frame
  • 3. Install corner posts and bolt them to the base frame
  • 4. Hoist the roof structure onto the corner posts and secure it firmly
  • 5. Install wall panels
  • 6. Position and secure the pre-welded top frame
  • 7. Install roof panels and doors/windows
  • 8. Seal all gaps with silicone caulk
  • 9. Complete interior finishing
  • 10. Connect utilities

Frequently Asked Questions

 

Can I Stack Multiple Container Units Vertically?

 

Both types of houses support vertical stacking. For projects with specific floor requirements, consult our structural engineers and ensure your foundation can bear the load.

 

Which Container House Is Best Suited for Extreme Weather Conditions?

 

For harsh climates with frequent high winds, heavy snowfall, or seismic activity, flat-pack container homes are the superior choice. Their welded frames provide greater structural rigidity and weather resistance. However, reinforced specifications of demountable homes also perform well in most scenarios.

 

Can These Container Homes Be Customized?

 

Both assembled and flat-pack homes offer extensive customization options, including:

 

- Interior layouts and partitions
- Insulation material types (EPS, rock wool, PU foam)
- Exterior wall finishes (wood grain, marble texture, solid colors)
- Door and window styles
- Electrical and plumbing configurations
- HVAC systems
- Bathroom and kitchen fixtures

 

Are These Modular Container Homes Suitable for Living?

 

Both housing types comply with CE, ISO 9001 standards, and local building codes in most regions. Key features include:

 

- Fire-resistant materials (Class A or B panels)
- Seismic-resistant steel structural frame
- Non-toxic interior materials
- Comprehensive ventilation system
- Electrical safety certification

 

What Foundation Options Are Available For These Modular Homes?

 

- Concrete slab foundation (most common)
- Pile-beam foundation
- Screw pile foundation
- Strip concrete foundation

 

Foundation selection depends on soil conditions, local regulations, and project requirements. For temporary installations, concrete piles or screw piles offer faster installation and easier dismantling.

 

Do You Provide Installation Support For These Prefabricated Houses?

 

We offer multiple support options:

 

- Detailed installation manuals with photos
- Assembly video tutorials
- Remote technical consultation
- On-site installation training
- Full installation services (for large-scale projects)

 

Most clients with basic construction experience can install our equipment using our comprehensive guides.
