Collapsible Container Garage 3×6 m – Fast-Install Modular Building

A sturdy galvanized steel frame that assembles without a crane — ideal as a garage, warehouse, office, or extra room.

This collapsible container garage is a prefabricated modular building that ships in sections and assembles on-site without heavy construction equipment. Thanks to its well-designed panel sections, installation is quick and simple, while the robust galvanized steel frame delivers a long service life and strong resistance to wind and seismic loads.

1. Why Choose This Product – Key Benefits

The most important reasons for the customer, ranked by priority:

1. No crane required for installation – unlike a standard 3×5.95 m container house, this building fully disassembles into easy-to-handle sections; installation is simply a matter of reassembly.
2. Strong, durable frame – hot-dip galvanized steel with powder coating for extra rust protection; main frame thickness is 2–3 mm.
3. Larger-than-standard size – a standard flat-pack container house measures 2.25×5.8 m or 2.438×6.055 m, while this model is larger at 3×5.95×2.8 m.
4. Earthquake-resistant construction – engineered to withstand a magnitude-8 earthquake, with wind loading calculated at 0.3 kN/m² (based on a 15-year design life).
5. Flexible configuration – units can be joined together to form a larger space, or stacked 2–3 levels high.
6. Versatile use – suitable for accommodation, office space, bathroom/toilet facilities, and of course, garage or storage use.
7. Cost-efficient shipping – a single 20ft container holds 6 units, and a 40HC container holds 15 units, significantly lowering the per-unit transport cost.
8. Customizable – available in multiple lengths (from 3×3 m up to 3×11.82 m), with OEM/ODM ordering options.

9. Frequently Asked Questions (FAQ)

Do I need a crane to install the garage? No. The building ships disassembled into sections and is assembled on-site without heavy lifting equipment.

How big is the standard model? The standard model measures 3010×5940×2810 mm externally, but other lengths are available (from 3×3 m up to 3×11.82 m), as well as custom sizes.

Can the garage withstand earthquakes and strong wind? Yes, the structure is engineered to withstand a magnitude-8 earthquake and is designed for a wind load of 0.3 kN/m² (based on a 15-year service life).

Can units be joined together or stacked? Yes, units can be combined into a larger space or stacked 2–3 levels high.

Does the unit come with electrical wiring? The standard kit does not include electrics — wiring can be ordered as an add-on.

How long does delivery take? Standard orders typically ship 7–30 days after deposit is received; larger orders are confirmed on a case-by-case basis.

Do you offer on-site installation service? Yes, for larger projects an installation team can be arranged; the buyer covers the crew’s travel, visa, accommodation, and daily fee costs.

Can I order just the steel frame without wall panels? Yes, a standalone frame kit is available, which loads even more efficiently into a container (up to 60 units per 40HC container).
