Casa Box Detachable Container House is designed for large-scale modular projects where transportation efficiency, fast assembly and future reuse are important. The fully detachable galvanized steel structure is connected mainly by bolts and screws, allowing the building components to be packed compactly for international shipping, assembled on site and dismantled again when relocation is required.
Under the standard configuration, up to 8 sets can be loaded in one 20GP container and up to 18 sets in one 40HQ container. Combined with its external drainage design and modular layout flexibility, the system is especially suitable for worker accommodation, mining camps, construction camps, site offices and other high-volume project applications.

Don't let a 10% price difference lead to a 100% project failure. Here is the truth behind the build.


We use an automated high-temperature baking process. The coating is uniform, UV-resistant, and guaranteed not to peel or rust for 15+ years.
Simple air-dried spray paint. It is thin and brittle, usually flaking off and exposing raw steel to rapid oxidation within 6-12 months.


We use certified 2.0mm+ galvanized steel coils for our main frames. This ensures a 20-year lifespan and safe 3-story stacking.
They use 1.75mm steel but label it as 2.0mm. This results in a wobbly structure and dangerous sagging under roof loads.


Crucial joints are full-seam welded and polished, creating a 100% airtight and waterproof seal.
Fast spot welding leaves gaps. This leads to chronic water leakage and hidden mold growth inside your wall panels.
While 20ft is standard, we can customize lengths and heights to maximize your interior space.
Choose from Rockwool, PU, or EPS core panels with varying thicknesses (50mm to 100mm+) to achieve the required U-value for your region.
Custom color matching with our automotive-grade baking paint, glass curtain walls for offices, or decorative external cladding for a residential look.
